I thought some of you may find this useful.

As some of you may know, when purchasing a geniune VM26, Kitaco and Takegawa/Trailbikes provide the carbs in different configurations with different Jetting.

However, it's the same carb base but with different jets and needle jet, jet needles.

Here's how they come out of the box:

Takegawa and Trailbikes
Main Jet 190
Pilot Jet 22.5
Needle Position 3rd from Top
Jet Needle 5E75
Needle Jet 332 # O-0

Kitaco
Main Jet 150
Pilot Jet 15
Needle Position 2nd from Top
Jet Needle 4J13
Needle Jet 249 # Q-0

Takegawa and Traibikes provide the same 606 Carb.

I hope this information provides itself useful, as I haven't seen this posted before.

hey z do u know the specs for the ogm v2?

I don't know Jack about anything Chinese or carbs that could be copies of the real article. Lots of the chinese bikes come with Copy Mikunis.

I know that Trailbikes, Kitaco and Takegawa sell geniune VM26's from Mikuni of Japan.

ahh ok lol

I recently found out there are available real and chinese copy VM26's. And I don't mean that so called 26mm oval bore Mikuni.

But the info is geat, strange that Takegawa and Kitaco have so big difference in main jet size.
Looks like people have a lot difficulties trying to get their VM26's dialed in, there are so much questions about it.

The kitaco is a VM26-665 then?

(I have a non-kitaco 665 with the 4J13 needle, mainjet came as #145, slowjet don't know. It was preadjusted for circa 120cc)

It's a 606...

You can get the VM26 Mikuni from Sudco also. They are a legit company. I believe you may be able to order them custom set up for an additional charge. You want the link to the round slide carbs.

Standard setting as they sell them are here:



Note the VM26-8074 is a spigot mount carb, which would need an adapter to use.

Picture and parts diagram for the VM26-606:



You can order jets and other parts directly from them also. I use them as a source for my old Yamaha enduro work.

I'm pretty sure it's cheaper to purchase the Mikuni 606 VM26 from trailbikes that's the same as the unit sudco sells.

The takegawa and kitaco units will be more expensive as there is some extra hands in the cookie jar.

I didn't compare prices, but I know that Sudco is a good vendor overall. Plus they can get you most any individual part you need. I have had good luck with them. Plus it is a good source for the jetting if you need to change out for your application.

It is good to know the shipped specs you posted, as that info is not always readily available.

The 8074 is signifcantly different than the 606. When comparing the two side by side, the main jet ends up off by no less than 5 sizes and the top speeds were different as well. The 8074 has a lever choke and uses a different pilot.

The chinese knockoff mikunis take the VM606 pilot and then use a Keihin main....and they underperform compared to a true mikuni.

Hey Z,

Can we open up a techincal forum for threads like this and sticky them up there????

i really think it would help people solving their problems.....i see so many questions repeated.......the really informative threads that are ALWAYS being asked we can sticky in there to keep em up top.

whadda ya say?

Z

Matt,

I have this in my Z50 Tech information sticky at the top of the Z50 page.

I dropped you a PM to discuss.

Everyone else, let's keep this thread on topic and a technical forum will be discussed internally.

I think I understand what I read, but I still have to confirm.

The china copy vm26:
TBolt USA, LLC » Pitbike Engine Parts » CARB KITS » China Mikuni VM26 copy

And the real japanese one VM26:
TBolt USA, LLC » Pitbike Engine Parts » CARB KITS » Mikuni 26mm Carb

The two carbs looking alike use different mainjets, and even the sizes of the jets cant be compared to each other??

Z

Correct, but if you look at the carbs above side to side, they are different. Lots of vendors selling Chinese Copy Carbs as geniune VM26 carbs. Tbolt points this out (good) while others don't (bad).

then you know who has to hear it

we sell japan mikuni vm26 from tb just like z spec reads


we also sell the mikuni copy carbs ,these are good units too and have there place in the market

Good point Vince. I have two brand new carbs...one came with a Lifan 150 and one came with a GPX160. Both are stamped Mikuni. Both of them are actually chinese knockoffs, that look just like a Mikuni, but are not. They are also not actually 26mm but measure 24mm at the throat.

At least the Molkt carb is stamped Molkt or blank stamped, but it irks me to no end to see a chinese carb with a raised cast-in letters reading Mikuni and vendors knowingly selling it as a Mikuni.

A true mikuni does actually run much better than the Molkt or the Copy Mikuni's for everyone's information.
