Snopczynski Posted March 21, 2009 Report Posted March 21, 2009 White smoke is bad, thats burning water. Black or gray smoke is 2 stroke oil. Quote
sheerider1026 Posted March 21, 2009 Report Posted March 21, 2009 check your jetting, look at those plugs. is it running hot?? also, i have seen different 2 stroke oils (such as motul) have less smoke than others, or hardly any at all.. personally i run amsoil dominator at 50:1.. which your premix ratio will change things also.. i like to seem some smoke from my exhaust (and i do).. some guys run there bikes waaay to lean to get power.. i go the opposite direction.. i run high compression and timing, but end up throwing a lot of fuel at the bike... but its not running rich.. however your motor is setup will determine how it will be jetted.. most of all. keep an eye on your plugs and engine temp.. it will let you know if its running too lean.. a lean condition will also cause detonation.. every bike will be different, JMO Quote
BANSH-alena-jol-EE Posted March 21, 2009 Author Report Posted March 21, 2009 sheerider hey man how can i tell if shes running hot, i mean when im reving her hard the pipes are scortching hot but i thought that was normal, she is running better than ever really, when i tried her today with the new plugs, on the base ring on the plug there was a silver patch nor colored at all, u can see it in the pic, maybe she lean on one side only? Quote
sheerider1026 Posted March 21, 2009 Report Posted March 21, 2009 when they get hot, the radiator will steam.. i have seen bikes that require a larger jet on one side than thr other.. i like my plugs to be chocolate brown.. hope that helps.. if they are burning totally clean, its lean, black=rich.. chocolate brown= good..

sheerider1026 Posted March 21, 2009 Report Posted March 21, 2009 did you just pull the plugs out after riding?? when checking jetting, you need to warm the motor up, then put a new set of plugs in it.. take it out fullthrottle pinned and go through the gears, then shut it off quickly and check the plugs.. if you let it idle for too long afterwards, you will not get a accurate plug reading for your main jetting.. does that make sense?

BANSH-alena-jol-EE Posted March 21, 2009 Author Report Posted March 21, 2009 i got what your saying, i didnt do it right, i just put the plugs in when she was cold and then warmed her up and went full throttle...but im looking for a brown color on the base ring or the bottom of the plug? is that what chocolait brown u mean, cause the white porcelain insulator peice stayed white, and there was a 2 small brown rings at the base of this porcelain, i sawed the spark plug to check, but the side elctrode looked scortched as well as some on the base ring on 1 spark plug remained shiny... ill try to do it more accurately today..

grizzly700 Posted March 21, 2009 Report Posted March 21, 2009 did you change jetting wen u put in the reeds? sounds lean to me. i would bump up ur main and pilot. Quote
BANSH-alena-jol-EE Posted March 22, 2009 Author Report Posted March 22, 2009 i have never jetted before, and i dont even know what size mains are in it!! i bought the bike 3 months ago and the dude dont remember whats in her. when i start the bike she has visible smoke, but once running nothing visible comming out!!!

AKheathen Posted March 22, 2009 Report Posted March 22, 2009 sounds like you are 1 size off to me. i would leave the pilot alone, and go up one sive from what you have. but varify with a proper plug chop Quote
peterlocal22 Posted March 22, 2009 Report Posted March 22, 2009 bike def seems to be running lean Quote
