If I jet and then put a header and silencer on my bike will it help with the power?

Question

I have a crf250r and was wondering how to get more power.

Answer 1

yes. the jet kit in the carb increases the amount of fuel and air in the engine. which means quicker throttle response and more power. The pipe will help also give more power and horse power out of the motor, look at whatever pipe you get. Each pipe has different effects. Some increase the bottom end and mid, where others effect top end. Its whatever you want for the bike. but yes the jet and new exhaust will help your CRF250

Answer 2

You dont need anymore power.

I'm pretty sure you are not riding that bike to its limit.

If you were, we would of heard of you by now.

Answer 3

Dear Eric.

There is not really much to do with the engine or tranny. They are almost all tuned to the max at the factory already.

You could tune it like a dragger but that just is for dragging and they scrap and rebuild after every third run if not the first or second run.

Answer 4

There is heaps of different opinions in regard to aftermarket  pipes and by how many people do have them on their bikes you would think that it must make a huge difference.  My sons bike has been set up recently by a specialist who is top in his field and has a dyno set up in his workshop.  he is stating that the difference it makes is really not there.  You may get some benefit if other work has been done to the bike, but otherwise it is still open to debate as to how much difference it really makes.  Anyway that is the advice that I have been given by a guy who really knows his bikes.

Having the right jetting is very important and that will make a big difference
