Just aquired this bike in a trade, bike cranks fairly easy even if cold.when cranked it will stay around idle rev for as long as needed but when given any good amount of gas it shuts off, will crank right back up. Took the carb off didn't really get to deep into it but took the bowl off any blew through jets everything was surprisingly clean. Out everything back together still the same.We pulled the plug it was black and kind of wet with what looks to be oil but overall didn't look to terribly bad in my opinion and don't even know if the plug was fouled if it would crank and run that good. Any help would be greatly appreciated and is is my first post.

Check the radiator fluid level. If the head gasket is blown it could cause this "lean" condition. Check the reeds also. Check the crank seals.

I think it is rich not lean and I put a hotter plug in and now it ranks first kick even when cold and idles perfect so I'm guessing to rich for sure. Now when I crank it rides fine actually good but after a little while fouls the plug also. Has all the power just can't keep the plug good.
