Kickstart ratchet wear
Johnniespeed:
Hello everyone! My kickstart has been slipping a little this summer and now with colder weather it slips a lot. I finally tore it down expecting to see chips off the leading edge of the ratchet and gear teeth, but found none. I looked very closely and see that the ratchet teeth are not machine surfaces, but they are a cast surface. I believe the teeth should have a 90 degree engagement surface, but they are rough cast and are angled. Putting a new ratchet and gear in will probably provide a temporary fix, but I feel that if they were machined better from the factory this slipping would never happen. I am very tempted to improve the engagement surface with a dremel tool. I need to know if anyone has every tried this before ? and did it work well ?
I value the opinions of the people on this site and will appreciate advice and comments.
Thanks John

Apparently nobody has noticed the kickstart ratchet teeth are not a machined surface. Ok so I will be the dumb guy to try something unproven. I took the ratchet and spur gear and reshaped the ratchet teeth so that they are a 90degree surface from the shaft. Now both of the surfaces have a flat contact surface and should not slip again. I have started the bike about a dozen times and ridden it twice, it works perfect. This is one of those modifications that will not prove or disprove itself until much riding and time.
It still would be nice to hear from anyone that has tried this or understands what I am talking about.

I bought a Gnarly pipe with the camera money. And now I want that new ERV3 xring chain to replace the ERV2. I have not tried to put the bike on my flatbed scanner. LOL John
