Apex Engine Mods?

[Machzspanker]

Are there any options out there as far as pistons or cams to increase horsepower in the Apex that anybody has tried or has any info on.

Supercharger.

Port the cylinder head. Just a guess, a basic "street" port job would probably see a nice 8 - 12hp.

TURBO

I am sure the turbo and blower would definitely give me more power than I need for my own good. Do you guys have problems keeping your tracks together? I have heard that is a big issue from the top end speeds, which I do alot of living next to a lake. Besides, I want to try and keep it sounding and appearing stock. Ya know "all I did was clutching!" type of thing. High compression pistons, cam, springs. That type of thing and still be reliable. The head work sounds good. Thanks for all the imput guys!

A properly built "all motor" engine can be quite satisfying and look entirely stock. I would suggest you pick up a book titled How to Build Horsepower, volume 1 by David Vizard. It will, at the least, give you a great education on the subject in an easy read. I have several good hi-po engines under my belt thanks to this book... and a few others.

You are lucky with the four cylinder engine in that many parts may already exist for increased power in the upper end. They of course come from the R1 crotch rocket... Cams, manifolds, and even pistons. The current bike engine produces 183hp... this from a production engine. If you decide to go this route, use caution and don't to "BIG" or you'll end up with a peaky engine that will only be good for Mach Z racing on the lake.

There will be very little power to be made porting the head on this motor. The ports are VERY well cast and straight.
