matt73ander Posted June 24, 2009 Share #1 Posted June 24, 2009 Okay since I'm laid-off now i finally have time to work on the bike. Got busy today and so far have the motor pulled out of the bike and waiting for help to put it on the work bench. bad part about being laidoff is all your help is working for money when you try and get them to help. Anyhow sofar no signs of cracks in the case but the drive shaft appears bent and the output shaft of the motor has broken off. Not sur what thi means for what i might find inside the motor but has me hopeing i can repair and not have to part out Link to comment Share on other sites More sharing options...
painterman67 Posted June 24, 2009 Share #2 Posted June 24, 2009 I really do hope yopui can fix it but if you decide to part it out let me know, I would like a chance to purchase the cdi/tci box. Again hope it is a fixable thing. These are grat bikes and I would hate to have to see another one taken apart. Good luck, David Link to comment Share on other sites More sharing options...

Venturous Randy Posted June 25, 2009 Share #6 Posted June 25, 2009 Matt, what is the status on your 2nd gear, since it is as I understand, an 83? Did you pull the output shaft and look inside yet? RandyA Link to comment Share on other sites More sharing options...
Dano Posted June 25, 2009 Share #7 Posted June 25, 2009 Before you split the case, look at the damper cam (right behind the case half of the middle gear) and see if it's split. That is the case with Big Dudes bike, we're working on a fix now. It also could be that all is fine inside the case and you won't have to tear it down.

matt73ander Posted June 25, 2009 Author Share #8 Posted June 25, 2009 No second gear issue here. I have a 90 now just forgot to update my bike on here, looks like my only problem is the shaft off the pinon gear broke and i have muffinman sending me one he has on monday. i didn't have to split the case but i will have to find new gaskets for all the side covers and a new u-joint. otherwise its looking like i just might get to ride this summer after all.

My 85 broke the output shaft last summer and I thought I was going ot have to part out the bike, but Rocket rebuilt it for me. Rocket is a great help and I am sure if you have any questions and concerns you could PM him or call him and he could walk you thru the gotchas that always crop up.

matt73ander Posted July 2, 2009 Author Share #11 Posted July 2, 2009 Well I finnally got the grease and grime of the last 20yrs off the motor and was looking at the bike to get ready to put it back in and found my fork seals that have been seeping slightly finnally gave out to. my question now is if I'm better off doing fork seals before i put the motor in or after. Not sure how much force is required to seperate them but I'm thinking having the motor in shouldn't be in the way and i can brace the bike better. any opions Link to comment Share on other sites More sharing options...
Yammer Dan Posted July 2, 2009 Share #12 Posted July 2, 2009 Not necessary but 400 lbs lighter would be easier to handle!! Link to comment Share on other sites More sharing options...
