[QUOTE="Scotty99983, post: 1376023, member: 116057"] Hey as said in my introduction i bought an RM250 rebuilt it with my dad and got it running. i got out on it twice the first time on it was just running it in then the second time i got out on it i was giving it a bit more id say bout half throttle gettin into the power band and then suddenly it died. my dad being the awesome mechanic he is ( he has had bikes all his life and has bout 36 years experience with them and done all his own work to them) he said it sounded like feul problems when it died on me and it wouldnt start it would only backfire a few times. so we checked the plug dried it off and there was still plenty of fuel gettin thru at the time and as we had just rebuilt it we took the top end off just to make sure everything was ok and it was fine. so we decided just to check everything else whilst we were at it and realised the timing had slipped so we sorted that aswell as there was still feul getting to the plug but it would backfire once or twice. so after that we tried to start it again as we rebuilt the top end and it will only back fire at us now and there is very little feul getting to the plug. we are going to strip the carb down and check to see if it has maybe picked up some dirt and clogged the jet which i think it probably has. but anyway the main thing im writing to ask about it the fact that when it wants to fire there is smoke coming out of the power valve vent tube. is this normal or is there a problem?? help is much appreciated as this is my first ever two stroke motocross bike same for my dad he has never had to work on a two stroke motocross bike (he prefers 4 strokes) [/QUOTE]
