Ok I am changing my manual camchain tensioner with an up dated 03 stock tensioner. My question is, I want to change the cam chain too, can I do that with the engine in the bike? Also I talked to a local suzuki mecanic he said that suzuki came out with a new roller chain and it cost about $100 buck's, any of you heard of this? And, if I go with a new stock chain should I buy new sprocket's too? Thank's for any advice guy's. (All this negative talk about manual cam chain tensioner's has got me paranoid)
