Bike sputtering & change of exhaust may nedd re-jetting??

I've purchased a 2005 crf 230 f and found the bike was fine for a few days but then started sputtering a little in high 2nd/3rd gears...i was going towards cleaning the carb...then i remembered there is a FMF aftermarket exhaust installed. I'm thinking that with the lean condition i have with the white plug that the previous owner may not of re-jetted the carb...would this be necessary??? as I believe it would be...I tried getting hold of the guy but he is out of town for a few days. can the engine be running hotter now in this condition and can any damage occur... I know this is long winded and any insight would be greatly appreciated...thanks

Generally when installing after market performance exhaust, jetting the carb is necessary. until you get ahold of the previous owner and find out if the carb has been jetted, you can try and adjust the fuel air mixture screw and see if that helps. and like any engine especially bikes, it is possible to sieze the piston. it can be riden, but be careful of over heating. hope this helps...

Chances are there is a water build up in the carb float bowls. The water comes from condensation in the gas tank. Try draining the carbs. Another possibility is carburetor main jets partially plugged up. You must clean the carbs if plugged jets are found to be the problem. Please rate my answer. Thanks. tombones49_152.gif

The BAFFLE fell off of Honda CRF 230 - replaceable? New exhaust?


I would say no. Is it just a slip on? Or was it clamped,? welded? How did it fall off? Even if the guts came flying out the end, they can be put back in. My exhaust system is just pressed together, I can pull it apart and rewrap the fiberglass and won't hurt a thing. Some exhausts are held together by a spring. Check it out. Hope this helps.

I have a crf 230f, and if i take the baffles out of the muffler, will it hurt my bike?


it can make the engine run very lean, this can cause piston damage, suggest you modify the fuel system to deliver more fuel.

Possible Problems?


I'd start with a valve adjustment, if it hasn't been done yet, it is overdue!

Bike is sputtering in high 2nd/3rd gear, best kind in idle


Sounds like a lean condition. Spark plug should be a tan brown.
I would say the carb probably wasn't drained prior to storage and your main jet is gummed up. Gas deteriorates very quickly especially in vented containers like the float bowl of a carb.
clean your carb for sure.

Honda 2003 crf 230 bike idles fine with choke on,dies with choke off


You sound like you have a blocked idle jet in the carb. Honda trail bikes love new oil, clean air cleaners and clean fuel. After a while a build up of tannins and crusty residue will invade the carby bowl and usually migrate through the carb via the jets and the emulsion tube where the jet needle runs. The easiest way to fix your problem is to remove the carb and go through it. Clean all jets and check float height and generally get it back to scratch. You will have to re- adjust your idle and mixture settings after you have fited it back to the bike. If you are not Mechanicaly savi then I would suggest you take the bike in to your local honda dealer and get them to go through the carb for you.. It's not a big problem and is easlily fixed.

Hope this helps...

Cheers...

I have a 2005 CRF230F and I am able to get up to 70+mph without all the aftermarket stuff on it. I hear the 03-08 are pretty much the same and all very indestructable and bad-***. Love my bike, its a great all-around bike (trails, sand, street, track) would never sell it!!!
