I just bought predator 90 this week. At idle it seems ok but when my son goes for a ride it seems to smoke alot. is that normal or is something wrong. again at stand still and when i rev the motor it seems fine only when he goes for a short ride it seems to smoke alot. it has been along time sense i had a two stroke so not sure.
Any help
Thanks

 

IF it doesn't smoke I'd worry about it! Normal for it to smoke a little more after warming up,because its heating up the exhaust pipe and muffler which over the years gets a little carbon/oil build up and tends to add to the smoking. If gets too bad you can remove it and have it boiled out. Machine shops can do it for you. Also check that you have a good air flow out of the muffler,I've had em almost stop up from carbon on older machines. Good luck
