break in

I'll probably get some flack for this but I believe if it doesn't work when it is new, it isn't going to work after some miles or time has been but on it. I start the bike let it get hot then let it cool and then let-a-rip. I have built several motors, atv, harley, and car and have never had a problem yet. Just my thoughts..........

easy at 1st, to let the ring and cylinder walls mate.

I rebuild motor on my spair time and i've discussedit at my dealership and they recommend running the motor at less than 1/2 throttle for 10 hours but never at a constant speed.

I guess everybody has their own opinions but I let it get hot, then let it cool down (idleing), Then run it no more than half throttle for a couple hrs and let it cool down, then run it no more than 3/4 throttle for a couple hrs and let it cool down. Then ride it like you stole it.

get it hot let it cool off then break it in the way your going to ride it no steady throttlefor fist few times
