Hi there my son has an 4 stroke vipor & the back swing arm gas snapped & my partner has took the rear ended of the quad apart & he is having problems removing the long bolt that connects the rear swing arm to the frame . Does anyone have any suggestion or know how this comes off .? Thanks

 

Welcome to the forums.
They can get stuck on hard. They usually get froze on the bearings.
A air chisle can be used.
FYI: you're going to ruin that bolt.
I recently rebuilt my 250R. We had to use a sawzall and cut the bolt between the frame and swingarm.
