SOURCE: 1985 CR125R powerband seems to lag before it hits

The only way to alter the band is to alter the expansion chamber to change the sonic pulse timing forming the port wall. The best way to do that is to try various chambers to see which design works best on your bike.

A good workaround solution would be to go up 2 teeth on the rear sprocket. This would allow the engine an easier and quicker run-up to the power band and more constancy within the power band. Yes, the top end speed will be less but you are quicker out of the hole and out of turns.

Engine oil level gets low within one month


Hi, Anonymous for this situation I would call my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry. If necessary, transport your bike to the dealer or shop and have a professional technician take it for a test drive, if it is in running condition, and give you a written estimate of repairs and answer any specific questions you may have about your issue.

Ive just done a top end rebuild on my CRF250R how long do i have to ride to run it in or is ok to go hard out now as it is only the top end ?


The biggest thing with a rebuild is getting the piston rings seated. Check your oil before every ride to make sure it's where it's supposed to be. Ride easy for a bit to get it warmed up, then feel free to ride it normally. Ride it up and down some hills. Putting a load on the motor and the up and down revving is actually good for seating the rings.

My 2003 KTM SX 200 lacking bottom end, top just rebuilt


isn't that a two-stroke? pull the jug off and check the piston/bore...if you can do that you're okay...Otherwise, call "Lazarus" at GT Thunder in Millersburg, FL and ask NICELY what to do.
P.S. he's a BUSY man be NICE to him!
