Mikuni Carburetors from China?

There are plenty of fake Mikuni carburetors online which are made in China. Mikuni does have a location in China. Do they manufacture carbs? My question is... If Mikuni makes carbs in China then are they the same as the ones made in Japan. Are the internal jets the same? Etc... I am looking to possibly replace a Mikuni VM24 on the boys old 2001 KX65. That is if a good internal jet cleaning don't fix the bogging problem.

Complete knock offs. But I have used them with success.

By the way, wire strands are your best friend. Use them to clean all the Jets.

Be sure to clean the pilot jets. The orifice is too small for a needle to fit through. I use a wire from a welders brush. Also spray carb cleaner through all passages. Good luck.

Pinesol works really well for cleaning carbs also and is pretty non harmful.
Won't hurt rubber etc.
Just gotta let it soak overnight.

Thank you guys for all the cleaning tips. I bought a cleaning kit off ebay for less than $10 and it has all the tiny brushes & needles. I also have a wire brush that I can remove strands from if needed.

So most likely the "ebay-China made" Mikuni carbs are knock offs even though they have a plant in China? I'm hoping a good cleaning will work. If not I'll purchase a rebuild kit.

Dont forget to replace the spark plug and gap it correctly, that can also ruin a two stroke running right real quick. The two cycle carbs are really simple and I bet with a thorough cleaning and plug it will fire second kick and run well.

Yes. I previously put in a new gapped plug, drained the old gas and then I mixed up a fresh batch of gas with Maxima premix 2 stroke oil at 32:1. Also put in a new air filter. And it still bogged after being ran at the track for over an hour. so now my last resort is tearing into the carburetor.

Yeah if it sat for any longer than a few weeks or a month that ethanol will break down and clog those little carbs quick! Its an easy job, let us know if you need any help or have questions!

Call Ron, the service manager at Kawasaki of Pasadena. Tell him your issues and if he can't steer you right, there is surely nobody on this forum that can.

No offense to anybody here, I just don't know anybody more knowledgeable about all things motorcycle maintenance than him.

One ebay seller said this when I asked if his was OEM... "This is OEM Mikuni however it was manufactured in Mikunis factory in China rather than Japan. Part number is VM24, and the carb is in stock settings with all the internal parts"

Some reviews of other sellers said you can't find replacement jets for the China made or fake Mikunis.

It's better to clean and rebuild the OEM carb rather than trying the cheap Chinese knock offs. Cleaning means soaking the body of the carb not just spraying it with carb clean. Be careful using the aftermarket carb kits as well. If your bike has aftermarket parts, such as a pipe, the jets in your current carb may be a different size than what comes in the kit.

Some reviews of other sellers said you can't find replacement jets for the China made or fake Mikunis.

For what itís worth, there are motorcycle shops in Houston that have parts department employees that are unable/unwilling or simply too uneducated to find the proper jets for carbs that they sell and service...even with a VIN and a factory microfiche. Most aftermarket carb reviews that Iíve read have been favorable, and I personally wouldnít hesitate to try an aftermarket carb on a play bike, especially given the potential savings.

I followed Bumblebee's advice and talked to Ron at Pasadena Kawasaki. He seemed very knowledgeable and took the time to check out the bike when I dropped it off. He thinks it's a jetting issue. I basically threw in the towel because the carb was clean when I took it apart. And I cleaned it again to be certain no build up was in the jets. I am anxious to see what he finds.

Thanks for all the advice fellas!
