I need help i have a 1990 yz 125 i have fire from the scatter plate to the cdi box i also have fire from cdi box what i need to know is how to hook it up to the kill switch and the coil

hello, usually you have 3 things for firing problems, stator and stator pickup coil, or ign coil, or cdi, i have a 2000 warrior 350, i just went through all that, you can buy after market cdi from procom engineering inc. i purchased one for my warrior 76.00 , it advances timing, hotter spark etc.most of the time it is the stator, pick up coil, both are hooked up together in the stator case, left side of motor,warrior cdi usually goes bad, havent heard of cdi on 88 model, may need to check with dealer.

buddy is that the cdi unit the stator plate and the magneto ???

did you torque the spring up when you put them in and did you put the push rod in the middle |???

It's one of the few that has a diagram.
Not sure what you mean by anti-rattle? The springs are for the pressure plate, and allow the clutch to grab, so you can go.

G'day i am a . YZ 125 j ...lets see now! You could perform these tests yourself.Check your plug CAP,if in doubt replace it with a new one. Take the below ohm figures and see if they match up. Pulse coil: white/blue and white/red= 310 ohms. low speed coil: Green/white and Black/red= 900 ohms. high speed coil: Green/blue and black= 55 ohms. hope this has helped in some way to helping you solve your problem.If it has please leave feed back.Ride hard , see ya,Tabbycat

the only way to tell is to match them up with out knowing exactly what year they both are its hard to tell but the change every couple of years

I would use maxima mt 75w gear oil in all 2-stroke trans.

it should mount under the seat
