here is the deal just bought this 99 sno pro. The guy that I bought it from said that there was something electrical wrong. When the sled is still cold it will rev out but after a little bit it will bog at full throttle and only run a about 3/4 throttle without bogging 6-7 thousand rpm. The seller had put a used stator and coil on and gave me the old parts. I put old stuff back in and still the same problem. I think the cdi could be bad about the only thing left. Is there anyway to check this or is it something you just replace. Anyway thought someone might be able to help me out maybe I have overlooked something.
