| 2002 TTR 90 smoking problems |
| jp said 2011-04-22 23:06 |
| My oldest son´s ttr 90 is smoking badly. It has great compression and runs great. I thought that it might be a ring but being a 4 stroke the compression is fine. It is blowing oil out of the exaust pretty badly. After about three hours of hard running time on the trails, you have to add almost 3/4 of a quart of oil (which is its capacity). My girls have a Suxuki JR50 2 stroke that smokes less than this 90. Does anyone think it could be a valve? I believe that I am going to have to pull the jug and break into the motor for further... but I do not have a manual o this scooter. Can anyony please advise. PS - This bike sat up for two years prior to me owning it. Thanks, JP |
