James-26 Posted March 24, 2010 Report Posted March 24, 2010 Hello guys, When fine tuneing the carbs with the A/F screw on the side of the stock carbs, when turning the screw witch way is fatter and witch way is leaner? At idle I have smoke coming from the left exhaust but not the right. My bike is a 95 shee with mods as followed 66.5 wiseco pistons stock head K&N filter, outter ware, no lid Boyesen reeds FMF good series exhaust ported and polished I'm not sure what pilots are in it but I seen the mains are 290's. Bike runs like a bat out of hell except for only side (left) blowing smoke and not the other. Well it will some but no where near as much. Should both A/F screws be adjusted the exact same or will they be different? How do I know if I'm tuned correctly? Also is getting a boost bottle worth the time or not? I have read before they help and some say they don't do shit. And last what tranny oil do I run along with witch 2 stroke oil is best. Thanks guys! Quote
lykins89shee Posted March 24, 2010 Report Posted March 24, 2010 Clockwise is richer on the air fuel. Sounds like your carbs are out of synch. My bike was doing the same thing (smoking out of one pipe) when i got it, the best way to synch your carbs is with a snail tool. I got mine from F.A.S.T. Racing , they are like 50 bucks but you can get your carbs perfect. If you don't have a boost bottle, i would not buy one they don't really do anything. Last I run Klotz tranny oil and 2cycle mix but its more of a personal preference. Quote

That is fixed now and shee is still smoking more on the left exhaust. Should the A/F screws be set the exact same cause they are right now but I was thinking about messing with the right carb A/F screw and see if that helps. I checked my plugs and they are a dull black/brown color, very clean, no carbon. Quote
lykins89shee Posted March 24, 2010 Report Posted March 24, 2010 My bike has always smoked more out of the clutch side when it is cold , and kind of clears up as you run it. I would not worry about it if the carbs are synched, unless it is white like a head gasket, or smells funny like tranny fluid is being sucked in (bad crank seal). As far as the air screws I have always kept them the same . Quote
James-26 Posted March 24, 2010 Author Report Posted March 24, 2010 Okay thanks for the info. One more question what tranny oil do I run? Can I just use normal Yamaha engine oil? What weight do I get. Quote
themuffinman Posted March 26, 2010 Report Posted March 26, 2010 Okay thanks for the info. One more question what tranny oil do I run? Can I just use normal Yamaha engine oil? What weight do I get. buy some gear saver 75w Quote
midlifecrisis Posted March 26, 2010 Report Posted March 26, 2010 I know a lot of the guys on here run ATF fluid in their gerarbox, some run 10W30, some run a mixture of both. I personally have never heard of mixing 10w30 and ATF but they say it runs beautifully and have always run it, so.............. As far as the boost bottle, buy some beer instead, at least that'll do something for ya! All boost bottles do is crack your intakes, lean out your bike, wreck cylinders and wreck riding weather!

I went to the dealer the other day and talked to a tech abt what oil to run in the tranny case. He told me to just run normal 20w 50 yamaha wet clutch engine oil is this right? I keep reading about guys running ATF in there case are we talking about ATF car transmission fluid? Then mix that with 10w 30 motor oil? Witch two stroke oil should I mix in my gas and what ratio? I bought some synthetic Gold Spectro two stroke oil. Any one try this stuff before? Quote
