Hey guys. Been a while since I've been here. Just got my 05 back together after being bit by the rzr bug for 2.5 years. Anyway, I took it for a quick spin last night with some 87 octane cause that's all I had around and i was chomping at the bit. It pulls HARD up to around 8K where for a SPLIT second, it miss-fires and then continues to pull HARD right up to the limiter. I have every intention of putting good fuel in it tonight but just wanted to see if you guys have ever had a similar symptom from too low octane. Only other things that are different from last time it ran is I adjusted to the compressor (too tight I believe) and a stock comp. piston vs the 11.5:1 I had in it. Dis assembled entire carb and cleaned before rebuild.
