trickedcarbine Posted December 11, 2014 Report Share Posted December 11, 2014 Did you make any other changes or modifications? Quote Link to comment Share on other sites More sharing options...
kryder Posted December 11, 2014 Author Report Share Posted December 11, 2014 It wont do it if i rev it at idle. Only when im moving. Its an 87 with .20 hot rods crank. Cool head. Boost blottle. Power wings. 35mm pwks. I may have fixed the issue. I put new needles in last week and it still pisses so il have to adjusy floats. When i reassembled carbs and everything i noticed that the left carbs bowl rubs on tge clutch hinge on the case. I got it so it just barely touches and doesnt move the carb when you pull the lever. Il see if that fixes the issue. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted December 11, 2014 Report Share Posted December 11, 2014 Any idea what jets are in the carbs? Typically a pop is lean. Quote Link to comment Share on other sites More sharing options...
kryder Posted December 11, 2014 Author Report Share Posted December 11, 2014 Im not sure. But i took it.out today and it ran like hell. Seems like im getting alittle oil splashing through the exhaust port? The needles are tight and i thought i had the float height correct but i guess not. Is there a standard measurement to use?

trickedcarbine Posted December 11, 2014 Report Share Posted December 11, 2014 Yeah, can't get taptalk to post the image I have but if you look on sudco's site they have detailed images for your carbs. Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted December 11, 2014 Report Share Posted December 11, 2014 A lot of junk out of the exhaust may be from electrical. Not getting a good burn of the mixture. And it'll pop and sputter a lot. Quote Link to comment Share on other sites More sharing options...

kawa110 Posted December 12, 2014 Report Share Posted December 12, 2014 Double check jetting and mixing ratio after Quote Link to comment Share on other sites More sharing options...
kryder Posted December 14, 2014 Author Report Share Posted December 14, 2014 What type of jetting should i start out with? I plan on taking it back apart this week. Iv listed the mods up alittle higher if anyone could help thatd be great. The carbs were from a 95 yz250 if that helps? Quote Link to comment Share on other sites More sharing options...
