hauser2169 Posted December 1, 2009 Author Report Posted December 1, 2009 maybe your float is set to high or the needle and seat is plugged,do you have gas pouring out the overflow tubes on the carb? Jeff nope. no gas coming from the overflow. i mean the carb was fine before the rebuild.. i dunno. i guess il try breakin it in more see if that helps. if it doesnt il just start messin with the carbs. also if i cant see any visible collant leaking where does the collant usally leak inside.? head? just tryin to get all the info i can when i go to work on it cause i dont got the internet out where im goin.

No Limit Powersports Posted December 1, 2009 Report Posted December 1, 2009 When it quits smoking you need to start worrying, remember this is a 2 stroke. It is burning oil, you put it right in the fuel remember, at least i hope you did. Typically if you have a coolant leaking you will get real white smoke and usually only from one side. Just check your coolant level and see if your loosing coolant. If its smoking more out one side then the other there are things it could be. Just give us some more info. Quote
TwistedSheeRida Posted December 1, 2009 Report Posted December 1, 2009 sounds to me like your motor is just running real tight after the rebuild. i wouldnt worry about it after my last rebuild it took a couple hours of riding to get it to even try and hold an idle. Quote
hauser2169 Posted December 1, 2009 Author Report Posted December 1, 2009 so should i even try switchin the slides?> or just run it Quote
volcrano Posted December 1, 2009 Report Posted December 1, 2009 so should i even try switchin the slides?> or just run it i didnt say switch the slides-make sure they are in RIGHT!!!if the cutout is not towards the back it will run like shit.seriously-take the 2 minutes to see if its right before you go ape shit.pull the seat and filter and look at the slides.if the bottom of the slides go straight across-thats ur problem-if the cutaway is staring you in the face,they are right and move on.

Your carbs are out of sync. I have had the same probablem with it idleing and running one one cylinder at idle. Also if one side is smoking more then the other the carbs are outta sync. Quote

Also if one side is smoking more then the other the carbs are outta sync. k so hopefully if i sync my carbs it will work.. i dont got a sync tool but i did find this http://www.youtube.com/watch?v=hpqeSpbq0PQ... will this work?? is there an easyer way. and will i fuck up the motor if i ride it around a little to break it in if i HAVE to have the tool to sync>> Quote
hauser2169 Posted December 3, 2009 Author Report Posted December 3, 2009 also i took my filter off and looked through to the carbs... i will open the throttle and they both move the exact same time. i think the one on the right has a little more open then the other Quote
