I’m brand new to 4 wheelers and just bought a 1987 Yamaha Moto 4 350. It has good compression and fuel, but no spark. I’ve looked high and low trying to find how to test all the components of the ignition system, but can’t find anything. This has a new CDI box on it, but I suspect it might be the stator. How do I test the stator on this? Any help would be greatly appreciated!

i just picked this up. was told ran fine but overheating issues led to replacing head gasket and head. has not ran since. he is not a mechanic but helped someone else who he could not get back to finish job, got aggravated and put up for sale. i was thinking timing issues. i have 110-120psi on all 3 cylinders so i think valves are correct. dont know about distributor yet. however i have no spark. i have no power going to ignition coil. tried to follow white wire but gets lost in wire harness. does anyone have a wiring diagram? can anyone tell me what conditions have to be met before starting. motor turns over so i would think all safeties are met but you never know.

First post here need some help/advice. I bought a 2001 king quad 300, vin number JSAAK43A212111871. I have been trying to do some basic maintenance as it runs but doesn't idle all that well . I want to take out and clean/repair the carb but when looking for parts it ask for model X Y K1 K2. How do I know which model I have? I have tried some vin decoders but they haven't told me. If anyone could recommend a carb rebuild kit for my quad Id appreciate it. Also any tips on tracking down an owners manual?

I have just recently gotten a yamaha big bear 350 atv and I think the carburetor is a little off on its setting,bc it cuts out at full throttle and it makes a weird pluff kinda sound 3-4 seconds after I hit the kill switch to shut the atv off. I don't know why it's doing that so any help will be greatly appreciated.

Recently picked up a 1991 Lt230e for repair. Compression is a little low Id say, around 80psi, I also have spark but the spark is odd . When cranking the spark is a constant arc. I’ve got it to sputter but never fully turn on. I believe the spark is my issue, being constant and not detonating at the right time. I’m not sure whether this issue is an electrical fault like some missing ground, a faulty cdi, or a timing issue. Any ideas where I should start?
