Hey guys new to the forum here. I recently bought a 2004 drz cylinder works 440 with stroker kit and hot cams. This bike is completely new to me and I love it so far. My question to you is, how can I find out if these mods are accurate without taking it apart? Is their some sort of measurement I can take to the cylinder? Maybe a 0-60 time? The guy had no receipts but I can defiantly tell it's not stock. I question the stroker kit to be honest.
