Dear all,Have just obtained a new head gasket for one of my bikes. Nothing wrong with the old, just wanting to up the compression. The new gasket is 0.5mm as opposed to the standard 1mm. Will this make a massive change to the compression ratio

I would like some advice about increasing the compression ratio and boosting the sadly lacking horsies. What parts need replacing upgrading to acheive this. I have thought of a better carb, and possibly a different camshaft (do two strokes have one

Thank you for this article, as well as the one on compression ratios. Would you please write something about various cylinder configurations?

think. Depends on the compression ratio the engine's running.An engine running about 9:1 compression should be ~ 140psi, 11:1 closer to 200.Compression tests should always be done with the throttle wide open. What's the engine based on?

anyone know of any decent place in the scottish central belt (east if possible) where i can get a piston shaved to lower my compression ratio? and if possible a ceramic coater? i saw an ad on ebay, a guy coats pistons with a metalic ceramic compound

Hello,Can anyone tell me what the piston deck height should be on a CBR600F3? (The height from the edge of the piston crown to the top of the cylinder bore when the piston is at TDC)Thanking you (trying to do some compression ratio maths without

has any one used a high output ignition coil such as Dyna and if so what difference if any? Don't think a high output coil would make alot of difference in an SM. The coils now days are pretty good, so unless you have a 17:1 compression ratio

.Diesels are more efficient than petrols 'cause they have a much higher compression ratio. The best (and theoretically only) way to improve the performance of an IC engine is to increase C/R. Hence a diesel running at 20:1 is more efficient than a petrol at 10:1.I
