any ideas

[yfzrider73]

I know that i need to start working on the inside of my YFZ 450 like engine parts but i was wondering if any one knows any other fourwheeler parts that i could get that would help my YFZ 450 performance not look other then engine parts. Check out my sig. to see what i already have done to my YFZ 450

Thanks

I don't really know of anything you can do to get more power, but you should take that rev box off. It really doesn't do anything for it because as soon as you hit the stock limiter the power just falls off the chart. A few buddies and I tested it over at KBR (local shop) on there dyno and it really just takes power from it.

stuff you could do to the motor would be Cams, port, stroke, high compression big bore, over sized valves, stiffer valve springs, lighten fly wheel, stiffer clutch springs

But some stock yz426/450 bike parts work in the yfz450

nova the rev box will give a lot more bottom end too and it may have less horsepower but it will still pull longer

that rev box did a lot to that bike
