KX450f stalling when riding. Bigger sprocket or flywheel weight?

Recommended Posts

I stall a lot when riding my 450 because i do a lot of trail riding. I also need a new front sprocket. Just wondering if I should get a bigger front sprocket (currently have a 13 tooth) or if I should invest in a flywheel weight and keep a 13 tooth sprocket?

Cool thanks. I'd say im going with the weight rather than the bigger front sprocket. I do a lot of tight trail riding so this should help a lot.

I put a 13oz weight on my 07. It helped reduce stalling quite a bit. I'm running 13/51 sprockets.

Putting a bigger front sprocket on is like putting a smaller rear sprocket on, the opposite of what you're looking for. The cheapest route is to go up 1 or 2 teeth on your REAR sprocket, then see if you still stall alot. After that a flywheel weight is a good but more expensive route. Are you having clutch issues at all?

You could try turning the idle up. that helps. and helps starting too.

Nope no clutch issues at all. Im worried that if I put a 13oz weight on it will damage the clutch.

With any gearing, even with a Rekluse semi-auto clutch, if you throttle chop too much, the KX50F will often stall. Regardless if EFI or a perfectly setup carb. Solutions could be more clutch use to modulate rear power with more constant throttle or more flywheel weight - but extra FWW or crank mass hurts handling agility.

Thanks for the info guys. Not very heavy into racing or anything so Id rather smoother power and lose a bit of agility on the throttle. Most trails around where i live are rocky and the ability to go slow without worrying about stalling makes riding more enjoyable.
