i always used SAE 10w-30 oil on all my dirtbikes,

My motorbike takes while to start, and when it does it has no power


Starting problem and low power in Yamaha YZ 125 can be related to bad timing, please get the timing chain in engine adjusted for proper engine timing. Also get the electrical and CDI unit checked. If the spark plug is old then change that too even if its working. If you want to check the plug for its fitness then you can do it like the way its described here in this article: http://www.thenetguruz.com/auto/diy-fix-for-car-or-bike-engine-knocking/

I have a chance to pik up a 88 yz 125 for a hell of a price and the guy says it wont start. No spark. electrical problem. says its the stator. I dont know that. So im asking, what exactly I can do to find...


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.

Will main clutch casing fit yz 125 2001 from 1997?


Hey Ryan! Long time since hearing from you.

When you say "main clutch casing" do you mean the right side cover for the gearbox or do you mean the primary driven gear (AKA "clutch basket") that the clutch boss (AKA "clutch hub") and all the clutch plates fit into?

If you mean the right outer casing > they are slightly different, '97 pn 4JY-15431-10-00 and 2001 pn 4JY-15431-12-00. The entire clutch is the same from 1997 through 2001.
