Re: Shouldn\'t we get
It sounds like a good idea to me. Trouble is, there seems to be a few different approaches as to how to resolve 2nd-gear problems. I've talked to Billy Rohm, and he makes a good case for his "cryo-treated" gearset... I know that APE makes a "heavy duty" gearset with re-designed engagement dogs, and then I also spoke to Patrick over at Fast by Gast and he told me that their undercutting service will ("9 times out of 10" in his words) repair the damaged area of the gears - FbG also said that for $20 extra or so they can weld up the dogs prior to cutting them in those cases of extreme damage... Patrick also said that they would be happy to inspect my shift drum and shift forks if I want to send them along with the transmission. APE offers undercutting services too, and Billy Rohm said that his cryo'd gearset is undercut as well. If you're made-of-money, APE offers replacement "severe duty" input and output shafts too. Then, of course, there's always the "replace it with OEM stuff" option. ...and THAT list doesn't begin to touch on the "put a 6-speed from a 750 in it" option.
No matter how ya fix the tranny itself, there's a whole collection of dowel-pins, gaskets, and o-rings for splitting the cases... and that can be done without opening the top-end, *or* you can take the opportunity to go ahead and do that big-bore kit/valve-job, etc. (and spend another $100 or so on additional gaskets/o-rings/seals) while you've got the engine out of the frame.
It would be *very* nice if there was a "how-to" sticky... but there's a lot of different approaches to "how-to". What works for a street motor that's stock is NOT gonna work for the turbo'd/blown/sprayed 1300cc+ monsters that some of you guys have built... and I don't need a million-dollar transmission in my streetbike.
One thing that *is* nice about all the dwarf-car guys "stealing" our motors is that at least that means that there are a *lot* of different options (and suppliers/shops) for fixing these problems... I've got a friend with a `80's 650 Seca that's got a blown tranny and I'm not sure that there are any replacement parts available for that.
