Would this help me more than hurt me? I have nothing done to the motor and I wanted to get a few "reliable horsepower" from something I was thinking a 13:1. Also if I got this piston, could I run hi octane race gas with it ? Can anyone tell me about how many HP I would get from this ? thanks..

Is this for your yfz?

Whats stock compression 12:1? If it is a 13:1 might get you about 2-3 hp

how close are you to alexandria

You need to come ride with me and my boys. we have a pretty good ramp built and we are working on a bigger on. Another thing is sometime next month we are getting our powdercoating equipment in so if you live close and you need some pc'ing well hook u up. nothing to big though. anyway get in touch with us because it is hard to find anyone to ride with, in this state that, that doesn't have a 4x4

You won't see much top end performance. Low end power however... :eek: a nice amount should be given. Well worth it, IMO.
