I just have to point this out because I find it funny, this is the Hyper GP4 that is soon to be out. Look at the fuel tubing, this was at RCX this year.

Maybe the better power delivery eats less fuel because it is more effecient?

Thanks for the info everyone.
You are kind of right. Reducing head clearance will increase horsepower but there are actually some negatives attached. You can actually increase head clearance and increase performance sometimes because in simple terms adding head shims will allow your motor to pull higher RPM with less loading on it. This will also reduce engine temps. It does cost you some low end performance and torque. I have dropped 30 farenheit with a .1mm head shim addition before. You will need to regear and retune. On a larger track I generally run 0.4mm shims even with 16% fuel.

Yes, it came with a manual . . . . . guess I'm not very good with pictures.
Hell, I was 18 before I figured out girls didn't have a staple in their navel.

Agreed.
That ninja star piece of the brake disk is pretty roughly stamped out IMHO. After a decent flatting exercise on the emery cloth, I had no binding but I also knocked the high spots off the teflon pads as mentioned, too.

AMGRacer - I am going to try and go both directions to learn what it all does for me. I think I am going to try and make more power with less nitro content instead of the other way around.

Sounds like a plan to me. Your motors should be fast on 16% IFMAR legal fuel.
