internal engine modification
i have been told that 4 stroke power for top end speed is mostly dictated by the cylinder head (springs, retainers, bigger valves). lightening the buttom end only helps accelleration. it does not make it faster. what does everone else think?

they work just like car engines. Same idea, move more air = more power. using bigger cams, valves, and head work all move more air. Balanceing and lightening the bottom end will help in accelleration, and allowing the engine to rev smoother and safer being that its ballanced.

2 words for lightenning the bottom = reciprocating weight

so lightening will not make the engine go any faster(lightening rods, lightweight pistons,knife edge the crank) just rev quicker. sounds like a lot of people waste there money working on the buttom end.

It does make you rev more quickly but it also "unlocks" horsepower that is robbed by these heavy components

isn't there a point where too light might decrease top speed. pistons,rods and crank ? or is this different since the supercharger is involved.

Trust me.

I have been using regular gas with ethanol and 87 octain. Now a new gas...
Gasoline - any speed difference?
