An age old 'trick' to fit a @#$ side stand spring is with one end of the spring in a vise bend it sideways and fit several pennies or small washers between the alternate coils on either side. Now with the spring lengthened fit it on to the pivot pins and remove the pennies. It works.

Hi Kevin, you can change MJs on Concentrics by removing the drain plug, if the NJ holder stays in place.

i tried that at first, gavin, but the jetwas in tighter than the holder, and it would spin out first. i snugged it up a bit tighter, i think, so i'll see whether they stay in.

the 220s made the norton motorboat on full throttle after a second or two, so it looks like the 200s are going back in. i'll see whether i tightened up the needle jet holder enough tomorrow.

Yes, and easy does it on the jet. 1/4"-drive socket, thumb and two fingers only on the wrench, little light twist. They're brass, so they grab good - never had one loosen by itself.

I rode my 70 Bonneville and my 73 Norton in the last few days, and yesterday I finally got started on my 79 T140D project. This is a fairly neglected but intact low miles roller with the engine in a box. It apparently had rust in the cylinders, and the guy I got it from had purchased several big parts, like a new cylinder and pistons, and a set of JRC carbs, and a gasket set. I had hoped to have this going last June, but I had to wait quite a while to get the title, and then my life got busy, so now with winter on the way here in Alaska, I will have until spring to finish this.

Anyway, my first task was to wash it several times, it was quite dirty. Then I changed those silly cowhorn handlebars to a set of superbike bend bars, and started to look over the stock master cylinder/switch/throttle on the right side--it looks like toast, so I am going to put on an 11 mm Magura master cylinder, a spare from one of my race bikes, a stainless braided brake line, and a Motion Pro throttle, also a race bike spare. That leaves me wondering about what to use for the right side switch --dimmer and kill switch--any ideas? Certainly there is some old Japanese bike part that would fit. I would appreciate any input you folks might have. Not a big day in terms of headway, but at least I got started.

The engine needs valve guides and reassembly, from looking at it, but these things always get more complicated. Other future tasks are rebuilding the rear master cylinder and both calipers and changing the brake lines, changing the fork tubes, rebuilding the forks, and rewiring it back to stock--the guy who had it pulled all the wires out of the handlebar switches and added rocker switches on a big fairing it had.

Today I'm replacing the kick start return spring on my B25. Ice done this once before without the nightmare stories I have heard from others. The only problem I find is that the spring can bind, and I have no idea why. Although I have heard it's normal for it to bind, I still would like to know the reason! I'm installing a B50 (6 wind) spring and I can't see the extra wind being thick enough to bind the spring.

In the last few days, I have been dodging heavy rain, enjoying the fall colors, and realizing that summer riding is about over in Alaska. I have also been carrying in boxes of chassis parts, including r. master cylinder rebuild, caliper rebuild, f & r braided stainless brake lines, a kind of cool looking new front brake rotor --stock, except drilled and lightened, etc. On the fork tube front, no joy--the first set I ordered had a defect in the thread, so I returned them, and the second ones haven't gotten here yet. After getting the chassis squared away, I will attack the engine. Anyway, it will be running by April. I hope.

the 1966 A65 bitsa thunderclone was still on the lift while i messed with the stinking kickstart spring. i always thought the nadir of BSA dumb was having to bolt and unbolt the seat to get underneath. now i know that the really stupid thing is the coil kickstart spring.

there is this little peg in the inner case you hook the inner spring hook to, then the other spring hook attaches to a plate that slips over the kickstart shaft and locks to it with a flat like an ignition switch. i tried everything to get that bastard on. i could hook the back hook or i could hook the front hook, but then couldn't get the plate rotated around to line up the flat, even with the welding gloves that mark suggested. finally i had a simian aha revelation and just installed the plate with the outer spring hook in place. then i took an awl and stuck it under the rear hook and just levered the inner spring hook over the inner peg like i was doing automotive drum brakes. worked fine.

but then it wouldn't start, which was my original problem after i replaced the points and condensors. i stuck a timing stick down the plug hole and discovered that while the timing specs are 7.22mm BTDC at full advance, the little tool that screws in the front of the 1970 engine had been locking the crank at 10mm BTDC. so i ignored the tool and set the timing based on the stick, but it still wouldn't start-- no juice at the coils. earlier i'd thought i'd just messed up the points, but they were fine.

eventually i traced the wandering electrons to a 4-way bullet connector under the seat (did i mention the seat fastening is stupid?) hot going in, dead coming out. the white wire forward out of it going to the ignition coils was in place, but loose. so i stuck it back in, the coils came alive, and the old tart rumbled on the first kick and fired up on the second.

so that is done now, and i'm going to go ride it tomorrow, instead of working on it, for a change. it's a great bike to ride-- very slow and very loud. i'm also going to take two long bolts and weld a nut on them about an inch from the end so that they stick down below the rear seat rails. that will let me bolt and unbolt the seat from the side without having to go poking around up in there like some demented BSA gynecologist.

. . . and just to point out my impartiality, the dumb award for triumphs goes to the incredible pushrod tubes. who would ever have thought that was a good idea?

Well, you know that's not all so bad.

On the kickstart spring, there have been a lot of different ways published over the years for hooking that up. You just rediscovered one of them. Anything from that to brute force with a welding glove on your hand works just fine.

The "very slow" and "very loud" part, you're going to need to sort out and tune your bike up, now that's not a BSA thing. If it's running right, it's making 40 HP and not any louder than anything else around.

The four-way connector going bad after 50 years ... well, who would have thought? Fifty years, why can't they make something that will last? wink

The seat attachment - that's a fair cop. Any other bike (including the OIF BSAs) has a latch and a hinge, or a couple handwheels like a Norton, not two blind bolts that require JUST the right length extension and a socket (luckily a 1/2" fits). For my two BSAs, I cut the head off a bolt to make a stud, Dremeled a slot into the top, drove them in, glued a heavy rubber grommet into the frame hole, and I just hook up the front of the seat and then push the two studs into the holes. Friction holds them there very well - unless you're going stump-jumping with the bike while standing on the pegs, the seat never moves and you just pull it off ...

Glad you got it going ... !

Kevin, re kick start spring, hold the flat tab on its flats with a hose slip/ jubilee clip, take a loop of thin wire round the spring hook and pull it round, easiest least hassle way .

The weather has been wet here In Argyll, so I whiled away a few hours making a fork brace for my 71 A65, using hand tools I cut an 85mm wide x 2mm thick strip of Stainless steel, Bent into a U shape 4 and a 1/2 " across the legs of the U, removed the front mudguard , and left 3 mm of clearance to the tyre , cut the ends of the U so that an extension hung down about 10 mm below the fork boss, drilled four mount holes to pick up the leg bosses..
Took the bike into Ali the LBS welder and welded one for each side of the old mudguard rubber mount 1/2 sleeves to the tails of the U.
Bolted it all up, the mudguard now sits 1" lower and the forks are braced, looks a lot better , not tried the brake in anger yet to see if the fork twist is less, roads are soaking and wet leaves everywhere.
Fitted new hagons to the rear, for some reason I clicked on A70 ( thinking at the time they would be the same as A65 shocks), bolted on nae bother, but they are about a half inch shorter, good because the rear axle now just clears the tail pipes, must have a shorter stroke as well? no bottoming out. Kommando has the Konis at the mo for a rebuild, they will go on again for next season. Bad because I have decked the centre stand without really trying.
Changed fluids and filters, cleanest sump plug so far, and gearbox oil came out a bit milky but clean.
The bike is running V well, most pleased with all aspects, particularly the new 5 speeds and forks, surprisingly good fuel economy too.
next on the list of things to do is the extra clutch plate thing , using one more plain steel and a 1/16" sheet of cork for the drum rear face.
Still getting a wee touch of clutch slip when cold.

My vote for most irritating, user-unfriendly and ill-designed piece on any motorcycle goes to the rear master cylinder on my T140--I spent the better part of 2 evenings pulling the rear wheel to pull the master cylinder and brake pedal and linkage and the foot peg and a bracket it is all attached to, along with numerous bolts and nuts holding the entire assembly on there, then did the master cylinder rebuild which is a story in itself right down to the arcane art of blowing through it and listening to decide how far to screw the cylinder into the case aluminum body, and now I am ready to put it all back together, with a braided steel hose. Good grief.

Today: removed the motor from the TR5T then rolled the chassis into the basement. Basement access is "fair" I'd call it, and I can manage a rolling chassis by myself. Getting set for winter work, in spite of the mild autumn ("hotumn") weather we've been having, it will change soon enough.

Friday: went out on the BSA for a couple of hours, tooled around on country roads in Concord MA and vicinity, out from 10:30am to 12:30pm, missing the school buses and commuters that way. Temps in the low 70s, with that autumn haze in the air, nice colors in the woods and fields, brooks and rivers brimming after the deluge of some days back.. The bike starts and runs well, excellent I'd say, a very nice ride. And no leaks. When I got back I drew up a list of 10 or so things to do next, starting with brighter lights, louder horn(s), add turn signals, add handlebar kill switch, and so on and so forth!

I'd post some pictures, but haven't figured how to extract them from my new camera grin

Got the BSA ready for winter storage and work: drained and dried the carbs, oiled down the cylinders, S100 Protectant on any chrome, and drained the gas tank, have to stop it from contacting the frame.

Well not today, but last weekend, I took what was probably my last outing for the season, riding with my son Peter in southern Dutchess County, NY. In this video, he's following me on his 2002 Bonneville. Wide angle makes me look farther away than I really was, but there's a brief glimpse of the Beesa at the end:

Today, pulled the wheels and suspension off the TR5T frame, next: more cleaning, then sanding and painting.

No hammered hardware, no frozen or crossed threads, no dents, dings, or scrapes -- well used, but not abused.

Hmm, no updates since Nov. 16... Well it's cold and gloomy here today (Saturday), snowed on and off pretty much all day. Good evening for a chat?

We heat primarily with firewood, so it stays pretty cold in the basement/garage. That is, if I want to get any work done in the garage, I have to get the kerosene heater going for a while.

I'm still playing with that Speedhut electronic tachometer. It's been back to Speedhut three times for repair - no complaints about their warranty policy or procedures. Apparently I keep blowing the gauge with voltage spikes. At first we thought it was on the power wires, so I ran dedicated power wires to the battery. Then it was determined that I had the coil pickup wire attached to the wrong side of the coil, the "upstream" side, if you will (polarity doesn't matter here), or the side that the (BB) ignition module is connected to. The tech at Speedhut said it should be connected to the "downstream", or "ground" side.
But when I hook it up that way (the gauge is operational now), the reading on the gauge fluctuates. When it was working before (hooked up "wrong"), the reading was accurate and steady (until the gauge failed, that is).

I have a theory that the problem now may be that the coil and the ignition module are sharing a wire to ground. That is, I have the ground wire from the ignition module connected to the coil terminal, and then a wire from that terminal to ground. It was hooked up that way out of convenience, since I have those double male blade terminals on the coil. But perhaps this is causing a problem for the gauge, so I'll try running a separate ground wire for the ignition module. Costs nothing to try.

A bit of rewiring is in order, so off comes the seat, carburetors, and fuel tank. The saddlebag strap across the fender obstructs access to the seat bolts, so I had to cut a hole in the strap on either side. Still, to get the seat off, I have to get up through that hole with a socket on a 10-inch extension and find the bolt blind. The saddlebag mounting is hokey anyway; I have muffler clamps around the shocks, where the bags mount to the ends of the clamps. I decided today, the bags will not go back on there like that. I will either devise a better mounting system, or ride with no bags.

Now I'm looking at the wiring, and thinking there may be a couple of other areas that could use some "tidying". Coming to the conclusion that the bike may be laid up for a while, I decided to drain the fuel tank, coat the inside with some oil, and put it on the shelf. Winter is official.

It would be better to use a Transil but a zener will do. Radio shack or similar will have one.

Yes, sorry but I didn't tell the whole story, it's such a long one. On the last repair, they said they added a "voltage chip".

Let me jump to the last test I ran, and see if this makes any sense: Gauge has three wires, red and black (pos and neg) power wires, and single coil pickup wire. I had the power wires hooked up to a standalone 12V 9AH battery, and the coil pickup wire attached to the coil POS (opposite the ignition module side). I'm running a single dual-lead coil. As I wrote, with the engine running, the gauge reading was erratic. I also had a volt meter hooked up across the standalone battery, and I saw fluctuations in the voltage, but in a downward direction, down in the 11s and then back up above 12. At one point the gauge reset itself, as if it had momentarily lost power. (When powered up, the gauge sweeps to 6K and back to zero.) Also, at one point, my voltmeter momentarily displayed "PloC". To know what that means, I will have to find the owner's manual for the meter.

I'm anything but an electronics expert, but based on this test, it would seem that the problem must be related to the coil pickup wire. They say that polarity is irrelevant on the coil pickup wire, but the current coming into the gauge on that wire must go SOMEwhere (after doing some work), but where, to the black wire? Also, Hillbilly Bike said he had one of these working ok on a positive-ground bike. So I more or less have to take their word for it that polarity on the coil pickup wire is irrelevant. But dammit, something on that wire is affecting the current draw of the gauge, in order to lower the battery voltage like that.

The voltage spike problem would not be on the pickup wire but coupled/induced onto the power supply which is then fed into the tacho.


Yes, in my limited understanding of the device, I figured it was something like that.

I do remember your suggestion, and no. Not that it's not a good suggestion, but I'm a fanatic about simplicity and neatness. The wiring is already more complex than I'd like, and it's difficult to hide anything on this bike. I feel I should not have to jump through any more hoops to make this gauge work. If rerouting the ground wire from the ignition module doesn't do it, I'm going to cut my losses and order a GPS speedometer.

I made 4 stainless steel adaptors.
They screw into the B31 crankcases and the holding down studs screw into them. I am fitting a Goldstar barrel and head, I have converted the head to through stud fixing
