Well today I decided to start to check out/tear down my Arco mini bike. I was wondering how to get the front and rear tire off. I think I might have to use a pry bar, but I'm afraid of bending the forks. Any suggestions on how to do it? Also, I was planning to drop a Predator 212cc on this bike after I get the body work done, but not sure if it will interfere with that jackshaft. Should I remove it, or do I have to keep it on? Any answers help, thanks.
