predator redline?

[uchi]

Wondering what my 04 500 predator will rev out to?

I think 03-04 would rev to 9000 with a stock cdi 05+ is 9100 and the crank will rev til about 10k before it pops on you. You have an aftermarket crank so it should be able to rev for awhile without damage but still limited to the cdi

Cool thanks man. What's the stock valvetrain good to?

[katch26]

hmm I dont know. The stock valvetrain is pretty strong but if youre living at the readline it would be better to replace them.

Right on. I'm sure I won't ever over rev it as it makes good power where it is now. But on the chance I regear it would be nice to squeeze a few more rpm out
