    1100 compression?

    115PSI or so per cylinder sound right?

    I know these run a lot lower compression than the 2 cylinders do.

    thanks.

    I thought 1100 compression was supposed around 150?

    Maybe on the sig it is because the actual 1100 is actually 1051 CC at least that what it says in the manual I have.

    nope- 150psi is for a twin- triple with a good guage should be about 115-125psi

    I'm just a hair under a true 1100 with all of the boring. 2 cylinders at .50 over and one at .75 over. I think it works out to something like 1090 or so. Either way, it'll end up being an 1100'ish BLASTER in the long run. I'm probably only going to use the raider hull for the break in and tuning, then swap it all into a blaster hull over the rainy season.
