so i lost spark the other day and finally got around to testing the stator and after searching i found that i should have 365 ohm of resistance between br/yl and ground and i have 340 ohm ? is that close enough and while cranking it should have between 30 40 vac and i get 25 vac? is the stator still good or bad ??
tested stator, is it good ?

I think that's a good reading, apparently you have a 61X stator (90-95) The Yam shopmanual for a 95 Superjet gives a very wide spec of 328.5 to 401.5 ohm at 20 deg. C/68 F. I just measured a nice low mileage stator and got 351.5 ohm with a Fluke meter about 78 deg ambient,
Your ac cranking voltage is not to shabby. Is the engine cranking fast enough and did you use an analog (got a moving needle) meter? Regrettably there is one more variable: when the engine and stator gets warm, resistance might drop a lot because layers of windings punch through.
Also, an ailing stator might work with stock cdi but not with a more demanding MSD enhancer.
Don't know where you are located, maybe some one could lend you a stator to try out (rare)

so if stator is reading good would it be the cdi? any testing for that in the shop manual, or how about testing for the coil in the shop manual ??

I'm in the same boat, everything is new except my stator and it runs as if it's hitting a rev limiter.
