Hello all, i have a 2003 CR250 and it bogs badly. The bike is new to me and is completely stock. When i give the bike gas, at low RPMS, it hesitates badly and then finally starts to pull away. I changed the plug and cleaned the carb. I am new to the dirt and 2 strokes. I have been riding motocross in about 90 degree weather. Any advice, suggestions, tips?

Thanks

Pilot is too rich. Have you tried turning out the air screw?

I have not done that yet, nor do I know how to. I am going to pick up a Clymer Manual, im sure that will explain how to. I also forgot to mention that I used 87 octane fuel, not sure if that played a factor.

I'm glad to hear you are getting a manual. Use the highest grade fuel available.

LOL, yeah, most people think DRN is a substitute for a service manual. It's just a suplement :laugh: .

Switch to 91 octane fuel asap, then look into jetting.
