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.

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.

I have owned my 84 Honda 200m for years now and I am wanting to see what i could do to upgrade horsepower , speed , performance , power etc and do it safely and not cause future harm to the engine.
I was thinking on getting a 200x piston, will this work and give a good power increase ? I have heard people have done this in the past and it works great. and i was also thinking on a 200x cam , will the 200x cam fit in this engine and make a difference also does it require the upgrading of any other parts and will i have to run 91 octane instead of 87 ? has anybody run this setup before and got good results ?
I was also gonna go with a 200x carb but not sure if i have to buy an intake to hook it up or will it just bolt onto the 200m intake and fit fine ?
If anyone has any suggestions and advice on what i could do it would be greatly appreciated ! thanks in advance.
