Mikuni VM26 Carb from Amazon

BBOWL10 · 11-30-2018, 12:51 PM

Hello,
I just received the VM26 carb that I bought from Amazon a few days ago. I checked out the main and the pilot jets to see what was in there. The main was a 100 and the pilot was a 40 or at least that was the number stamped on the jet. I thought the stock pilot was a 20 for these carbs. Can anyone who has purchased one of these let me know what stock jets were in their carb? I am going to change out the jets but I thought a 40 was really too big for a stock carb. Let me know!

Mine came stock with a 20 pilot and a 100 main. A 40 on the pilot is huge, you could order a jet kit for it or send it back for another one.

Someone must have grabbed the wrong pilot jet when putting it together. I am going to replace the jets anyway but I doubt I will have any use for a 40 in the future

I have looked at probably 2 dozen carbs on Amazon this past week, don’t really know which one to get etc but I had noticed in the bottom page details some come with huge jets. Some of the pit bikes take a 40 or 50 it seems.

If the carb fits your bike correctly then just order the jet kit that covers your spectrum.

These are fake VM26 carbs it's not surprising they mix up jet configurations. The good thing is that unlike the stock PZ30 it's easy to source pilot jets cause it's VM26 jet compatible where the PZ30 is just needle-jet compatible with the VM26 and still has a unidentified pilot jet.

This is an image of the real 30mm VM26.. Notice the branding on the throttle stem and they all had the plunger style choke.

I thought the lever choke looked a little odd.

I just received a Mikuni clone for the hawkster and it also came with a 40 pilot and it has a rebuild kit with it that has no markings on any of the jets supplied. I thought it may have been a wrong stamp so I tried it out.... Rich as can be on idle. So it’s definitely a #40. Oh, and this is my first post. Great stuff on this site keep it up gents.

I also ordered the Mikuni and it’s 40 pilot and 100 main. Will also need to buy some jets

Jet numbers for your pleasure.

Pilot Jet = VM28/486
Link - https://jetsrus.com/a_jets_by_carbur...-486_pilot.htm

Main Jet= N100.604
Link - https://jetsrus.com/a_jets_by_carbur...arge_round.htm

I highly recommend OEM jets, but if you want to keep it on the cheaper side of things then spring for the OEM equivalent. Don't waste your money on cheap jet kits from Amazon.

Size wise a 25, 27.5, or 30 for the pilot jet depending on mods and elevation. The 30 only seems to work well for guys at sea level though. At 1100ft I found the 25 to work well on a stock bike, and the 27.5 to work well with mods though it was a tad rich on hotter days. Ideally I should have drilled out a 25 pilot to a size between the two.

Main jet - 105/107.5 on a stock bike. 110 for just intake or exhaust, 115 for intake and exhaust are good starting points. Adjust as needed for temp and/or altitude.

Needle clip 1 down from center (4th from top) worked well for me, but depending on factors you may find 2 down works the best (bottom notch).

You stated vm28...but we were talking about the vm26 - 30mm carb. Is this the correct info for the knock off vm26? TY

Answering a question with a sales pitch. And you wonder why people tend to treat you the way that they do?

The pilot jet used by the knock off Mikuni VM26 is a VM28/486 style jet. Don't let it confuse you too much. It's just the same style pilot jet the VM28 happens to use, but since these are knock off carbs, they just happened to decide to use that jet style.

Actually, that is kinda cool. I do like how you included the sprocket and plug too.

DJ, I run the "Mikuni VM26 30mm" in the link....though they come with an additional kit now too! Never had a problem with them.

I'm curious.. Why are people worried about the better EFI kit being half the order-cost of the bike itself when you eat 2/3 the cost the second you order the bike in the first place? A mint or even heavily modded&mint Hawk or Magician gets nothing but sub $500.00 offers on CraigsList and Facebook-Marketplace..

It actually makes more sense to keep one and properly set it up than to sale or part it out. Best case scenario parts appreciate a year or two from now when plastics and electronics disappear from Shenzhen markets, or a neighbor just buys it off of you on a whim..

Also as a reminder: If it's got a 48mm stud intake and switch-choke it's not a real Mikuni. Even if it says Mikuni on the stem and Japan by the bowl(this actually exists on Amazon under a China seller even though it's a trademark violation).
