XR70 max rpm?

Recommended Posts

The xr70 seems to rev to a point and stop - does anyone know how high that is? Is it limited by valve float or rev box?

We have opened-up the air filter cover and the stock pipe tip and geared it down.

Is reving it until it doesn't rev any higher too much for the engine? It seems to need all the rpms it can get in 1st before shifting into 2nd...

Thanks.

The stock CDI does have a rev limiter, but I believe the engine flat out runs out of steam before it gets to it.

Yeah, the gear spacing on the 70 is stupid. Even with an inner rotor kit, the bike can't wind out far enough to not bog going 1st to 2nd, or 2nd to 3rd. Change sprockets to gear it down a bit, and drool at aftermarket transmissions, thats about all there is for it.
