  1. I'm surprised it says 86 octane with a compression ratio of 12.0:1. High tech aluminum engines with high compression can run lower octane than what would traditionally be guessed at. There was an old magazine article that showed dyno tests on some high octane/compression bikes that actually produced more horsepower/torque on gasoline that was less than the factory recommended octane. Nobody knew why the engine would do that.

    yeah it sounds weird man. my 600 is pushin 12.5:1 and the manual says to run 87. not sure with such high compression why it runs lower octane. the 750 runs 12.8:1 and calls for 91. does .3 really make that big a difference?

  2. ^ Yep, I'm registered there too.

    Its 520 chain with 15/50(-1+2),bmc, gytr shorty from the newer r6, there is a sound clip link below my pic. And a pc on the way which will need tuned, where do I go for that?

    damn dude i thought your rear sprocket looked HUGE. is it 50 in the rear b/c you have the S model?
