Im so pissed off i have only had mine a week and nothing but problems. This machine sat for a year or so so i pulle doff the carbs and cleaned the shit out of them you can eat off these things but as far a the cylinders they are the same. I know its something stupid i have owned so many atvs, snowmobiles and bikes and this one has got me stumped. Please let me know what they say im going to keep on searching.

what needle clip are you at?

[pr0blumz]

You most likely have an air leak. Do you have a boost bottle and did you put new plugs in?

[botlfed306]

3rd position and yes new plugs b8es @.28

[botlfed306]

No boost bottle

[pr0blumz]

No boost bottle

 

Have you checked the intake boots for cracks?

[botlfed306]

Yes they look like they are in great shape. I just started it and it was a bitch to fire but i ran like shit for about 10 sec the left pipe was hotter than the right pipe dont know if that matters sice it only ran for such a short time.

[2-stroke_couch]

yea i did, br8es and a white bros... im pretty sure its an air leak too. i just took it in this morning. i did my carbs all over too but the needle i forgot. and the same with me i cant find for sure whats doing it. i sparayed everywhere with carb cleaner to find the leak and i checked the boost bottle and it was all sealed. they should call soon or tomarow. ill post when i find out. and mine only start by covering a carb until it starts.

[pr0blumz]

Turn your airscrews all in the way in. That should make it easier to crank and should let you find an airleak by sprayin starting fluid around the intake boots, around the head, and cylinders base gasket.

[banshee#44]

i had the same problem just go through your carbs and clean out your needle jets with carb cleaner if that doesnt work just clean out all your jets and if that doesnt work. well i dont know lol

[pr0blumz]

Yeah a good carb cleaning would help and a compression test too.

[2-stroke_couch]

dont mean to steel the thread but i have done that and i have good compression in both cylinders but the left side is running better than the right. its weird man. i got tired of it so i just took it in.
