Spark plugs black

Take it to the track and beat on it.Don't be afraid to get the temp up to around 210*,it will seat the rings,then check to see what the plugs say.

Some guys tend to set idle mixture before the engine is up to temp. If you do it cold, it'll be way fat, as a cold engine wants a rich mixture in order to idle worth a flip.

Flog it. Then set the idle mixture while hot.

Good time to hit the chassis dyno, load the rings, and do some tuning....

I know I need to run this thing. Ive only been messing around with it. I cranked it today and let it run ripping on it and got the temp up to about 160. When I first cranked it it smoked out the passenger side but the plugs look the same on both sides. Anyway as it warmed up it started to stop smoking and when it was good and warm it cleared up completly.The smoke just don't look black to me. But for it to stop the smoking im figuring that's a good thing. What could actually be going on?
Thanks

Whats Wrong is you need to take it to the track and run the livin Piss out of it and quit worrying so much about every little thing someone says or you read about.... That's what the matter with it...

It is time for the rubber to meet the road, if you feel more comfortable load it up, take it to a TT and make some licensing passes until you are comfortable, because unless you built it to sell it...It is time to DRIVE IT LIKE YOU STOLE IT

Yea you guys are right.
Thanks

The rings only seat up with a load on the engine. Stop idling it and free reving it until your ready to beat on it. Until you do your just washing the cyl wall with fuel. The rings dont like that

Ok thanks men.

I rebuild atv engines, after each rebuild I have a process I go through.

I have a long hill just in front of my house I use to seal the rings on. I start at the base of the hill at 1/4 throttle and short shift the transmission so the engine will stay under load as I drive up. Then when I get to the top I turn around and coast back to the bottom. I do this a couple of times and each time I give it a little more throttle and more gear to keep it under load while watching the smoke coming from the exhaust. When the exhaust starts to clean up I am usually at full throttle pulling the hill short shifting to keep it under load. I do this until the exhaust is clean, (while keeping a feel on engine heat.)
