biggun6ss Posted January 15, 2006 Report Posted January 15, 2006 I have a friend that had his cylinders honed and he is getting a new set of pistons as well. He used a dremel and some emry cloth to smooth up the exhaust side of the cylinder. He didn't notch at anything, just buffed it out making it really smooth where the pipes go into the cylinder. Will he see a hp gain that is noticable? Quote
smokincycles Posted January 19, 2006 Report Posted January 19, 2006 not sure but i opened the exhaust up on my cyliders about an 1/8 inch id, and polished them up with a rubber type dremmel stone,now i can tell the difference in longer harder pull down the road,,,and a crisper trottle response on the bottom end....other than that i have twin k&n filters with a 290 jet,,,i think im gonna bump up to a 300,and the 310 was just a little to much,,,it was boggish on bottom end,,,and i have fmf pipes in which i would rather have t-5 toomeys Quote
