I've had a search around and there is very little to no information on electric start conversions for A65s. This must mean there are non, or am I looking in the wrong place?

Never seen one but have for a B50 which the maker says it was too much effort to consider doing it commercially.

The A65 will be similar, new clutch and two piece primary cover.

Hi Peter

I'm working on a electric start system for the A65. Bit early to show any photos as its still in chunky bit of alloy which will be machined back later. Works off the clutch basket and reduction gear to a bendix starter, this all sits neatly under and behind the carbs.

Shall post some photos once its in a more refined state.

regards

John

with 7.5:1 pistons (or lower) you should even be able to start it by hand....

HI Allan

Quite correct. However you might want to consider older people with dicky knees/hips etc who still like their A65.

Your actually very right John and I do support your reasons for doing it. I’m hoping it’s something I won’t need for some time however two up and touring, a leccy start will prove useful for anyone.

Ive seen photos of one converted to electric start so it is doable .....no idea about the engineering of it or where i saw the pics. I have an idea it used some sort of italian starter unit

Seems like you'd need a battery with some serious CCAs and a place to put it... and then a charging system to keep up with it.

I have one. I think it is a 65 motor. Built it some years ago. Used a 1000cc gold wing starter (reversed rotation), starter clutch from a honda 450. It drives the crank on the primary side. I cannot post pictures on this site, The stater motor fits nicely in front of the cylinders.

The Norton Commando starter I use has a GL1100 starter driving a GL1100 clutch on the crank, must be very similar to your setup. The Commando being non unit gives you a lot more room, so be very interested in how you got yours to fit inside a much smaller space.

Hi Mark,

When Meriden put an electric starter on the 750, they fitted a 14.5 Ah, 125 ccA conventional lead-acid battery.

The Motobatt that's about the same physical size as an original A65 battery - the MB9U - is 11 Ah but 140 ccA.

Meriden fitted the high-output version of the Lucas RM24 3-phase.

Hth.

I use an Antigravity 4 cell Lithium Ion battery in my T140ES. It never balks. That said, I no longer use the electric starter for fear of damage from the hokey design.

Hi John

Thanks for posting Rocket man's photos of his ES system. While it works for him, I'm looking to have mine a little tidier with the starter sitting below and behind the carbs. The outer primary cover will be standard with no cut-outs, with the idler gear coming through the top of the primary case to drive the starter ring gear which replaces the inner of the three chain sprockets. The starter bendix will then drive the idler gear.
Sorry its not far enough on to show any photos at the moment, shall see about posting some once there is a little more shape to it.

regards

John

I would love to see that. I could not find the room to put the starter under the carbs. Also very limited space around the clutch basket.

After doing similar as John suggested on a Commando ie motor in magneto position, chain drive down to shaft and the inside the primary a second chain to the sprag on the end of the crank and it was a really tight fit, it would be impossible on a Unit motor.

Just got this in my inbox today, I know its not electric and not even for a BSA yet but maybe adapted in future as this is on a triumph. Anyway it caught my interest and thought maybe some of you guys might like to have a look. Another approach to same problem and maybe a seed for one of you designing and fabricating fellows.This was done by engineering students. Hope its alright to post link, if not pease delete.

Agreed Andy its not very elegant but rather an engineering exercise and posted more as an idea that may have merit with some refinement. Seemed simpler to retro fit on bike than all mounting an electric starter and all the pieces and fabrication involved with getting it to work. Daryl

hello peeps.
John e mailed this stuff to me , asked me to post some pics.

Here goes.
BSA A65 Electric starter system

Below is a description of my electric starter system for the A65.

Outline:
The starter motor is located over the gearbox casing, sitting under the carburetors. The starter drive to the engine is by way of a bendix type motor driving an intermediate gear onto a starter ring gear, which replaces the inner row of teeth on the clutch drum. This necessitates replacing the triplex primary chain with a duplex primary chain.

Fitment & components:
The chain guard casting behind the primary casing is cut out to allow the starter motor to be positioned as low as possible. A base plate is then made to sit on the primary casing, which will then be welded to the primary casing. This will also carry the intermediate gear and via a cut out mesh with the starter ring gear on the clutch drum. Attached to the back of the base plate is the starter motor carrier plate, the starter motor bendix drive gear when energized will mesh with the intermediate gear.

Explanation of the attached photos:
Photo 1: This shows the starter motor sitting roughly in position on the engine, although 20mm high due to the chain guard casting being in place.

Photo 2: Again showing the starter motor sitting on the engine roughly in position, but again will move towards the primary side by 25mm.

Photo 3: Shows the base plate and starter motor carrier plate mounted on the primary casing with the starter motor and intermediate gear. The clutch drum also has an alloy plate simulating the starter ring gear.

Photo 4: Shows the front/side view of the unit in position, further trimming/tidying of the covers and round of the corners shall be done later.

Photo 5: Shows the view from the side/rear of the unit in position.

Photo 6: shows the starter motor and carrier plate, final orientation of the starter motor shall be finalised when installed into frame.

While I’m having the starter ring gear and intermediate gears made progress will be on hold.

Regards

John Hill 31st October 2018.
