I know this probably in the wrong forum but.. I can still try :D so heres my problem I just bought a Yoshimura pipe for my 110 KLX and I need to jet the bad boy now because when I kick start it, it will start up but shortly after it will just stall out from idling or it lags up when I try to give it throttle and then dies, the only way around this so far is if I shift into first quick and then give it some it goes. So what would you recomend for me to do with jetting etc. I'm running stock carb and air filter btw.
I just took it out trail riding to with me the other day with me and my friend if that helps at all

 

whats the plug look like?blackened is rich white is lean.
you shouldnt see such a dramatic change with just a pipe swap, something else is going on.
you may want to play with the mixture screw by turning it out a quarter of a turn at a time ,once you get to 3 turns out its time to go up a size on the pilot jet
get back with us on the plug we can go from there

 

Alright thanks I'll look into this weekend with my dad also since he use to do 50s and **** back in his day . But yeah my brothers total stock 110 I know his idle is wicked low since he dies in 1st gear if given to much throttle, but yeah alright ill double check this ****, kinda glad I use to play with RC nitro cars
