Long story short I blew up the clutch basket and it got the best of the bike... We replaced the whole clutch and basket but the crankshaft is chewed up from the basket getting in between the gear from the clutch and crank and it now sounds like a ducati. I know I'm going to have to replace to crank thats a given but is there anything else I should be looking for that might be messed up too. The bike runs fine just don't want to push it and mess it up more. Also what do y'all think this is gonna cost me parts wise? Is there a better way to fix the issue or am I basically looking at a full rebuild?

Well, if you intend to do the rebuild yourself, it's probably going to be the "cheapest" way to go. But a new crank will cost you just over $1,000 by itself. That's not including the bearings and gaskets and all the other stuff you're going to need for the rebuild. I would plan on at least about $1,500 in just parts. If you're having a shop do the work, tack on another $1500-$2000 in labor. :sad: And at that point you'd probably be better off getting a used motor and swapping it completely.

Is it just the flywheel gear that's messed up? Or did you bend the crank? You may want to try contacting Marine Crankshafts or APE to see if they could repair the damage for less than the cost of the new crank. But I don't know if they work on the gear itself or just do straightening/journal work.

I'd be leery of a used crank, but that's also an option if you can find a good used one. Again though, you're going to need a lot of little odds and end parts/gaskets, etc for the rebuild.

I can get a new crank for about $800 brand new but idk if that is completely needed. And I'm having a shop do it because I do not have the tools or time for it at the moment unfortunately. The part circled is what is chewed up and causing the noise the crank itself is not bent as far as we know. Thanks for the quick response btw!

Yeah, that gear is integral to the crankshaft. It's machined as part of the crank and not separate. Unless you can find someone that can repair that, a new crank is needed. Check with the guys I mentioned above to see if it's repairable. Is it missing a tooth? Or just burred up? If the motor was in the high RPMs and this locked it up, there's a possibility a journal is bent. But maybe not.

Good luck with getting it back on the road!

Well dang. I'll check with the guys you mentioned above! Also all the teeth are there they are just chewed up some but I guess I will just replace the whole crank. Thanks for the help I really appreciate it!
