I have a 89 Warrior that runs great. I got alot of slack in my chain and wanted to tighten her up. Well I get back there and the 11/16 bolt will not turn at all. Is this common? What do I do? I am going for a 3 day ride this weekend and I need to get this chain tightend up before then. Any help will be more than appreciated. Thanks

 

Seems like mine was a metric socket. With a stuck bolt that big I just get out the 25" breaker bar. Nothing has withstood that so far. You could also try an impact and/or apply some penetrating oil ahead of time to reduce the small chance the head will twist off.

 

I will try some oil. I already tried a impact with 120psi and got nothing. I will oil it up real good and see what I can get it to do. Thanks

 

Used alot of WD-40 and a 3ft breaker bar and got it off. Wow what a task beleive they were greased good. Thanks all
