Coming from a Z400 to a yfz450r THE YFZ450R idling sounds like its gonna blow and the piston and conrod gonna shoot up through gas tank. BUT IT RIDES NICE WHEN YOU GET ON THE THROTTLE PULLS AND PULLS..
I was curious, what makes a high compression piston better than a OEM piston? I mean they all serve the same purpose but some how everybody says you can get more out of a hcp. Thank you in advance to anybody that explains this to me.
