Why I am fitting an Electric Start to my Triumph Bonneville T140v 1977
Some Exerts from My original diary’s in 2018
Its no good kidding myself have severe arthritis in my knees hips back and shoulders and using the kick start is becoming not only more difficult to do but also more painful for me to do.
I can still use the kick start but logically I can rapidly see a point coming in the next few years when I won’t be able to fire her up any more.
I have no intention of giving up on riding my Triumph Bonneville so I need to find a solution.
I am originally a qualified Scientific Instrument Maker by Trade and also worked on the shop floor as a maintenance engineer for too many years to remember before moving into management.
So instead of giving up, I wondered I can use my old expertise and skills as an engineer to help me continue to maintain and ride my motorcycle.
The Bonneville was fitted with an electric start in the early 80s with the ES the TX and the TSX versions.
That original Meriden/Harris electric start was sadly unreliable, and was mostly removed by the owners, and the bikes put back to standard. There are still a few exceptions out there but generally this was the case, so I cannot just fit one of those but maybe I can reengineer and find a solution with something like it.
So I need to investigate where practical all of the reported failure reasons of the Meriden and Harris Electric starters to see if I could find a reliable solution.
Eventually I decided on buying a Kit from LP Williams as I liked there idea about having the sprag resolving around the Intermediate shaft rather than the shaft and sprag being one part and the whole thing revolving in the crankcase housing-
Watch the video of me installing the basic kit it along with some other modifications to the electrics to see what I discover and work out a way to make it all reliable.
Many thanks to Andy at Pazon for re-programming my Pazon Altaire E Ignition with coil energise delay.
Hope you enjoy my four part video on the project - Auta a dopravní prostředky
You can buy most of the components from Harris and LP Williams. The sprag that rotates around the intermediate shaft is only available from LP Williams or make your own like I did lol. The special Pazon Altair with the coil delay program is also available to you now that want that. Just include in the order that you want the coil delay Altair E and mention my name so they know to make one for you.
Choc block?
Great job and great to see it all come together.. ES makes such a huge difference I'm saddened those in charge at the time never saw the future even when it was staring them in the face..
Agree its not that hard really. I have designed a new stronger sprag as well that's in part 4 and will put that up on here soon.

I am interested in the modification to the Pazon ignition, I am about to fit an electric start to one of my Commando's, my question is does the modification mean the kickstart can not be used if the coil doesn't spark for the first 3 compression strokes. I would want to retain the kickstart just in case.
When you order the Pazon you need to ask for the special E version Altair, if necessary mention my name to Andy. Kick start works fine as it ignores the first or second pulse which is enough to avoid kick back obviously. I always put mine to TDC now before kicking and its fine electric or kick start. On the Tridents and TSX ES Bonnies and one 850 Commando I once worked on years ago, I just used to put a simple coil delay timer on for 1 about second that had a switch to turn it on and off so you could select electric or kick. That worked fine but sadly vibration used to destroy the relays so needed to change them every six months. It worked fine but for that. No more wrecked starter motors or bendixes on those lol. Hope this or these ideas are of use. Ride safe.
