Hi All especially RF,

Just to say that at 1400hrs today, my rebuild project finally fired up on 3rd kickover.
So the wiring diagram modifications (thanks to RF)worked perfectly with a charge as well.

Things to do :
1. Put a new gasket on timing cover to rectify bad oil leak.
2. Adjust throttle cable and reposition needle because of sooty mixture on plugs.
3. Adjust timing.
4. Check all fasteners.

Here are a couple of pics of the bike for interest






Regards to all

What a beauty. Fantastic.
I like the rubber on it. What brand are those tires?

Hi Kev,

Thanks for your encouragement.
Only problem now is to strobe the ignition. I have a strobe gun, know how to set it up using a separate battery etc, but am a bit confused at the actual strobbing.
For example, I have TDC & BTDC set up using the special tool inserted in the crank hole to locate the appropriate two slots (seems I have a later crank/flywheel fitted).
Have marked up a white dot on the Boyer rotor and the bike fired up.
What I want to know is, do I losen the Boyer stator screws and when point the strobe light, actually adjust this plate whilst the engine is running ? or will I get a shock that will throw me over next door's wall.

Colin,
Thsanks for your kind response. The tyres or tires (USA) are German Metzler Classic tyres
The front one is a ME11 and the rear is a ME77.

I had these on my previous rebuild (1964 T100SS), and proved to be excellent road holders.

The strobe should be used on the drive side with the rotor cover off. First use your timing tool to see if the rotor timing line is lined up with the little metal pointer attached to the chaincase cover, at the bottom of the opening. That is where you aim the strobe. I would not loosen the Boyer except to make adjustments when the engine is not running. It is easy to see if it is spot on then shut down and make a small adjustment on the Boyer. Restart to check.


Without frequent roadside repairs there is no fun in riding!

Lovely slippers you have there. What brand are they? Do you find they grip okay in the rain when you're running out to the shed? wink By the way, very nice bike. It's a credit to you. Give yourself a pat on the back from all of us in cyberspace.

Lovely bike, worth all the hours you've spent.
Where did you get your rear number plate?
I've got a new rear plate holder for my 69 T100S and have been searching without sucess for a suitable 3 line plate. I can only find square/oblong ones which just don't look right, but your shaped one looks spot on.

Cheers Paul

Hi Mr Bean & Paul,

Glad you like the slippers Mr Bean. They are comfortable to ride in, have good treads and go with my image of beainf a pensioner and all that.

Paul, I obtained the number plate at an autojumble this year. I have seen plenty around. There is one on e-bay going for 5 at present with one day to go (or buy it now for 25).The site is

http://cgi.ebay.co.uk/Triumph-Rear-Numbe...1QQcmdZViewItem

The actual legal sized number plate itself is then cut to fit the tapered shape of the number plate holder.I see you come from S'ton. My late friend's 1959 Tangerine Bonny is on display at Bikers of North Baddesley. We bought our Bonnies new in 1959 and his was owned by him until he died last year. It's NOT FOR SALE.

Gordon gave you the right answer on the strobe. The white dot deal as explained in the Boyer paperwork is only an approximate static setting to get the bike cranked, then you MUST use the line and pointer inside the 3" window on the primary case.

Nothing criminal mind you, but here's several other items to look at....

Nice example of the SPG, but your battery will charge more reliably if you'll take the RED fuse lead back to the SPG also.

You may wish to add a "grounding" wire from the SPG back to the tail lamp. This will help your tail lamp work reliably in all weather. This is non-stock, but highly suggested.

If you bolt the oil tank hard to the frame, as it appears to be, then the mounting tangs will soon fall off the tank. The oil tank must be free to move around. Place the rubber between the frame and the tank tangs.

Although it keeps your coils neat and secure, the U-bolts may end up killing your ignition coils from too little surface area. In order to work, the igntion coils do not have to be hard-mounted at all. You may have better luck with a rubber lined Adel clamp ( http://www.hi-line.com/wiremanagement-adyyellownitrilebutadieneadelclamps/186 ), or a rubber hose with U-bolts over that. Look how they mount coils on an OIF 650/750 model. Nothing touches the coil body except rubber.

On your list of "things to do"... swap items 2 & 3. Set timing, THEN start loooking at the plugs.


Boy, you've sure got a "looker" on your hands there. You might have to carry a club to keep the women off when you slow for traffic stops. I'm very partial to the orange & white. In fact, my own tank and fenders leave this Wednesday for nearly an identical treatment.

A+. Your "gold star" is on its way! bigt

Thanks for the reply.
I already have a new plate holder.
I spoke to Tippers in Rochford Essex today. If I supply them a template they will make me a pressed ally shaped plate to fit, for a supplement.
I hope it looks as good as yours.

Richard,

Many thanks for your input. I will certainly take all you mentioned on board and let you know of my progress.
Have to run the gauntlet of rain here in my slippers. Wet old England and cold as well. Reminds me of my time in the Brit military in Korea (the 1950's). Swing that lamp. Told you I was old. laughing
All the best for now

Jim

Richard,

Just a quickie on timing and having got the engine running etc, what am I actually looking for on the subject of strobing and adjusting the Boyer back plate ?

I have the rotor cover off and because there were no timing marks on the rotor, I marked up TDC & BTDC using the tool that fits in the two flywheel slot.

Jim

Is it usual for the coils to be under the seat? Mine are under the tank.

Fantastic paint job BTW. I've been giving some thought to having my 1969/1970 T100S repainted in a similiar scheme.

Hi Matthew,

The only reason the coils are located under the seat is that my fuel tank is from a 5TA unit speed twin and never had the cutaway in the fuel tank to take the coils, as did the T100's etc.
