Can I get away with a hone and pistons? Go up to a 340? Edited May 30, 2007 by blacknred03 Quote Link to comment Share on other sites More sharing options...
FASTOYS Posted May 30, 2007 Report Share Posted May 30, 2007 Looks too lean for your altitude or bad gas. Send me some pics of the cyls and will see if they can be honed. Quote Link to comment Share on other sites More sharing options...
letsgetthisdone Posted May 30, 2007 Report Share Posted May 30, 2007 (edited) Looks just like mine did, except it went all the way through the piston....lol. Prolly bad gas man, cuz my jetting was good, and your piston looks like mine, except like i said, that main spot in the middle actually went through...lol Edited May 30, 2007 by letsgetthisdone Quote Link to comment Share on other sites More sharing options...
BansheeKid15 Posted May 30, 2007 Report Share Posted May 30, 2007 Not to hyjack your thread, but i took a look at my pistons yesterday, they have the standard carbon, but where the spark plug goes (the size of the inside hole) there is a circle on the top of the piston, should i be worried? Mods are in my sig, 270 mains... Im going to pismo on thursday so some quick advice/info would be greatly appreciated! Quote Link to comment Share on other sites More sharing options...
halfrack Posted June 2, 2007 Report Share Posted June 2, 2007 That looks almost identical to what my piston in my Fl250 looked like. The problem was a lean condition caused by an air leak. Quote Link to comment Share on other sites More sharing options...
