I have Matts E-start kits on my 71 ( Matt did the install ) and am nearing the end of restomoding my Dads 72, ( Pop passed at 89 last year )using nothing but Matts upgrades,including the E-start,doing this bike the way my Dad would've enjoyed it,though he would never get off the dough it takes to do one of these bikes proper.....everyone's "Proper" is different.My proper was to incorporate all the best that the Norton R&D guys have to offer,all Matts stuff,Comstock head,JS mortorsports lightweight rotating assembly.....I had and continue to have no "price point".I then contracted with a super guy Jack @ deer park cycle in Dover De
Jack is a OG triumph- norton guy from back in the day when we had the triumph east coast distributor in Towson Md......this might be too much for this thread.....sorry....point is Matts E-start kit is simple,elegant,super dependable.....like every single part I've ever bought from Matt.If you are thinking about a E start retro kit......Matts is the crown jewle.
This is a tribute bike for my Father,buddy and riding companion for 30+ years,I miss him and will honor him with this bike......Lots of photos once I figure out how to. Post a build thread I'll get them up

I gave up trying to use the photobucket mess. Got a premium membership. So much easier and I am not pulling my hair out, not that I have any!

I have a bunch of pictures of the install that I did a little over a year ago, here are some.

Again, thanks a bunch for that. One question regarding belt tension - the instructions say the lower belt run should deflect up to the bottom of the alternator wire grommet. I'm not at that point yet, but from the pics it looks like about an inch of deflection? Seems like a lot to me.

Your photo mentions having it loose enough to not hit the boss at the top of the inner case. Doesn't the crankshaft pulley make the upper run taught when running?

I am planning on installing a CNW starter shortly. Thanks for the pictures and I will be watching this thread with interest.

You would have to ask Matt about that. I just didn't want the belt to rub the boss where the gear is. I have opened my primary up recently and the belt looks OK, just a bit of dust from wear I think. John in Texas

Not exactly. The engine doesn't run that smoothly. The crankshaft is speeding up and slowing down every cycle, so the tension in the belt is also varying. That excites it into various vibrating string harmonic modes, so it does move up and down. The less tension on the belt, the further it moves.

Good point.
