How do i know when im over revving the engine? I own a CRF150F and drive it mostly in the higher revvs but i wonder how do i know when im revving it too high?
DannyMoto07 said:There's a point where revving it any higher is pointless. It all depends on the bike's powerband. You should feel the power band kick in once you start going... it feels a little different in every gear depending on your speed and motor RPM's.
Once you start getting to the top end of your power band (between 3/4th and WOT) it's kinda pointless to keep revving higher. The meat of your power is going to be in the mid to high-side of your powerband.
Cruising around between 1/2 and 3/4th throttle is perfect... but if you're racing, in a field, or on a wide open track... go ahead and revv it up a bit.
2 things... Clutch your shifts (you'll shred your transmission), and don't ever hold it at high RPM's when cold or in neutral... especially if it's a 2-stroke.

Also, what data suggests that you have to clutch every shift or you will "shred your transmission"?

IndyYZ85 said:I only use the clutch when starting & stopping and to regulate the power to the wheel..
I don't use it to shift. I have learned how to shift my bike without the need for the clutch.. For me, it's a bit faster and one less thing I have to worry about when riding.
But.. this has been gone over very thoroughly in these forums many times.. Do a search and I am sure you will turn up plenty of info and opinions about the proper way to shift a bike.
That will do almost nothing to the clutch plates. Taking off from a stop in 5th gear will hurt the clutch plates much more. Shifting under power without the clutch (if the transmission will even let you shift like that) would be harder on the gears than anything else.DannyMoto07 said:In reference to the "shredding the transmission" I meant shifting with the power on... not backing off or clutching will kill the clutches.
