AKheathen Posted August 7, 2010 Report Share Posted August 7, 2010 hey guys another quick question whats the best way to break in a new top end is there a good method? use the exact premix and ratio you are gooing to be running. do 2 or 3 full heat cycles and retorque the head (a few will be loose) then, a few plug chop runs, including getting it warmmed up first to full operating temp. then, just ride it like you stole it and it will be broke in with the best ring seat you can get, and jetted right Quote Link to comment Share on other sites More sharing options...

AKheathen Posted August 7, 2010 Report Share Posted August 7, 2010 ok lol im cofused dude what do u mean by heat cycles/and retourque the head and plug chops?? heat cycles is where you start it up and let it run with the rad. cap off, and blipping the throttle once in a while untill it reaches operating temp. then, let it cool copletely untill everything is cold to the touch. i couldn't find the link to the plug chop info, but basically what you do- get it up to operating temp. if it's running decent and revs out clean, then find a strait stretch and change plugs out with brand new ones real quick. start it up and immediately pin it and keep it pinned through all the gears. then pull the clutch and kill the motor at the same time and coast to a stop that way. pull the plugs out and put the old ones back in and ride back to read them. cut the treads off and read the porcelin. there should be a 2mm solid chocolate ring all the way around near the bottom. more than 2mm=rich less than 2mm, or light in color= lean. also look at the plug for specs of aluminum, which would be from lean/deto.

vbanshee Posted August 7, 2010 Report Share Posted August 7, 2010 wow that seems a bit much to do just to break in an engineis that really the only way man ? thats a good way to break it in. but usually i do 3 heat cycles. MAKE SURE YOU RE TORQUE the bolts! then do three 15 minute riding sessions one at 1/4 throttle. second at 1/2 throttle then full throttle all in between riding sessions let the bike cool completley Quote Link to comment Share on other sites More sharing options...
