    I don't know the carb diameter off hand, the clutch hole and groove are for adjusting your clutch. There's a set screw at the center of that piece you took a picture of, and you stick a nail, small screwdriver, etc through that hole, use it to hold the crown in place and use an alen wrench to turn that set screw to adjust your clutch play.

    When you do set your clutch play, don't adjust it too tight. You lose play as the clutch wears, and if you set it with little-to-no play, you might burn through faster than you think.

    Thank you very much guys!!! Ok 2premo I figured it out, it pops of the cover with out screwing with the springs. I poped it in the case it has 1/4 in play up/down and sideways. It does fit tight in the case though, Is that enough to make it work. are there any other options vs splinting the case to replace half of it. I do have a machinist friend I could talk to. machine them both and add a needle pin bearing?? Its not good, hope it can be fixed, I'M not wanting to split this dam case.

    do you have the needle bearing between the idler gear and the shaft? if you have a shim between the bearing and case it may be ok. the needle bearing needs replaced occasionally..

    yes I did replace them. the shaft does not spin in there though right? It got this bad because there was nothing left of the bearings that were in there. I need a few opinions on it how it is now, and if it will work as is. . It does fit tight into the case side. I can machine down the case, put a hardened seat and machine the shaft to fit in the seat, this way it is all tight. It would be a lot of work and I would still have to split the case but its the only way I can think of to fix it and make it strong. Any other simpler ideas are welcome.

    The shaft does not spin in there. I would think that you could drill out the case to make the hole round, press in a sleeve and leave the shaft stock (or maybe replace your shaft with one that isn't chewed up, and leave that one stock). That approach is a common repair when the holes in the clutch cover go out of round on older model clutch covers. Later model clutch covers came from the factory with steel sleeves.

    Ok that sounds like something I was thinking about, It just has to much play. Enough to make me worry anyway. Little by little, I was hoping to have it going this coming up weekend. Hmm Hmm, o well, nice little project.

    I got the shaft cleaned up as good as I could without taking to much off. I had the gear hardened, I would rather go through pawls faster than have the gear wear out like it did. I cleaned up the inner case and machined a steel pilot bearing to fit as a retainer sleeve to fix the problem. Need to take another 4-5 mills more off though, its to tight still. I found a lot of small cracks in the case someone has epoxied up. Some under the water pump. So i will be hunting for a new case if anyone knows anyone who may have one? I will call halls on Tuesday, maybe they can get an updated aftermarket.

    Looking good. I do think I mis-spoke on the shaft though, it does spin when you are kicking, but stays stationary when the bike is running, so you will want to have a little clearance between your pilot bearing and the shaft.

    Also, the gear faces the other way :)

    When you refer to case, are you talking about the clutch cover or crankcase itself? I'm not 100% clear based on context. You can get clutch covers from HVA Factory. Crankcase you may have to watch ebay for.

    HVA Factory is the only source for current production replacement clutch covers. NOS is non existent unless one pops out of the woodwork.

    thanks guys. Yes Eric i fiddled around with it and figured out it would spin on kick, I clearance it to hover in there tight but spin as needed. I will start checking out the covers.

    The carb is a 38mm the 36mm has a thicker wall.

    Drill and ream the hole and epoxy or press in a oil lite bronze bushing. But I would use a harden steel washer as a thrust washer between and case and gear. Go by the teeth line up when you shim it.

    I'm fortunate enough to have a nos replacement that the factory sent my old man since the originals corroded. It's mint never been installed. Don't know which of my bikes it'll end up on yet
