I bought a new carburetor for my 02 trx250ex and it the carburetor cap is has a wider diameter than the original. I can't figure out for the life of me how to remove the old carburetor cap from the throttle cable.

Before you go any further with your carb replacement I have to ask, is the new replacement OEM or Chinese? If it's Chinese you will be wasting your time fitting it.

Welcome to the forums! I agree with Sam. Seen 100s of accounts of chinese carbs not working at all. I have personally seen 2 and both ended up in the scrap metal pile. Save yourself the headache and get oem. Or clean and rebuild the original one. My .02

Thanks to both of you for your quick responses. There's no "made in ... " stamp at all on the new one. But it does have a KEIKHINKT stamp on it. The original has KEI*HIN JAPAN stamped on it. Is keikhinkt a knockoff made in china product replacement for keihin?

Where did you buy it from? How was it listed? Is the cost comparable to an oem one from Honda or was it a $50 special? If these don't check out, probably knock off. Especially true if you are seeing differences compared to your original one.

Quick google search says yes. That is a china knock-off keihin carb.

Thanks for letting me know... I guess I'll just do some serious cleaning on it. Do you think some of the components from the knockoff (ie, rings, gaskets, springs,bolts, screws, floats, etc.) can be used to replace original parts?

Nope! Get a gallon of Gunk carb cleaner. Take your carb apart completely following the FSM instructions for disassembly and reassembly. Once you sure that all rubber parts are removed, put all of the hard parts into the carb cleaner and let them soak at least 24 hours. Then blow every hole, passage, jet etc. out using compressed air and reassemble to specs per the FSM.

Be careful taking it apart... there are tiny o-rings etc., that can fall out and ruin your day.

I've never used a Chinese carb but from what I gather you can use the rubber parts (if they fit) but your better off buying new OEM jets/screws etc

Just to add... Dental floss is great for cleaning inside those jets and tiny holes too ;-)

You can swap gaskets and o-rings if they fit but the float valve rarely works.... may leak uncontrollably... best to buy OEM or reuse the original if its still in decent condition.
