Help with YZ125
Hi guys, need help
When i start to ride my yz 125 hard, it just bogs and dies, and then wont start again. I think it is fouling the plug. Its also really smoky. I know its to do with the mixture screw, but im not really sure what altering it does, does turning the screw in make it run richer? or leaner?
Thanks

Re: Help with YZ125
Pull the choke fully up, untill it clicks.. give the bike a kick if its not starting in 5 kicks then somethings wrong.
either not enough petrol is getting there or to much is.
my mixture screw is 3 1/2 turns out, only mod is a FMF fatty can

Re: Help with YZ125
What colour is the plug after you've ridden it hard.
When was the last time you had the crank seals done?
