Box stock rpm?

[Nickell]

Whats a safe RPM for the box stock class clone? I just got into kart racing and got a ducar clone and am planning to run the box stock class. Need to know how high you can rev them safely.

6,300

WITH BILLET FLYWHEEL not stock flywheel

Even with the stock flywheel they will turn 6500 just fine, its not going to explode unless you have been beating on it with a hammer or something, there are plenty tracks around here where people have ran the stock wheels for years turning up to 6500 or more, never heard of any exploding or any issues there. But as far as the RPM in box stock, it really depends on what your track considers box stock, if its aftermarket filter, big pipe, and everything else that the clone class allows, then 6300-6500 would be the max you would want to turn, anything over that is just making noise, not power. If its small pipe and stock airbox, 6000-6300 would be the max, just what iv found to be best. Really depends on your mods, like the cam, timing, how good your springs are, and few other things.

And how do you know this? You need to think before you start giving out advise like this! You must not have heard of the magnets coming out of the stock wheels from over revving.
