Mikuni Carb Question - How do you know which one you need?

How do you size these things when purchasing? You see 28mm but they dont tell you the intake is 36mm!

Can someone shed some light on which Flat Slide Mikuni carb that will work on a 150cc engine? What intake do I need?

"THANK YOU"

With a 28mm carb the venturi is 28mm, the flange which goes into the mounting boot which in turn bolts on to the manifold is 36mm.
So you need a 28mm intake manifold with the correct rubber mounting boot for a TM28.

(if you are going for the 28mm version)

Also if your going with a flatslide you better know how to jet a carb with your eyes closed because they are not for someone without allot of patience.

So you would recommend a Round Slide Mikuni with 28mm intake? Is that what you ask for 28mm intake. Best to place to buy this GENUINE Mikuni?
What if I have a pro dial it in?

I thought you were going with the Yosh carb. How come you're changing your mind to the Mikuni?

The Yoshi carb is 499.00
I had some paypal laying around and was thinking about it but then I bought the 150cc motor so that money went away.

Well what do you guys run for carbs??
125cc and larger?

nielspbr · 02-26-2009, 11:31 AM

Bike one: Skyteam st90(ZB clone) with 138cc jialing, mikuni VM26-665 on a takegawa manifold and rubber and K&N filter.
Bike two: Skyteam le mans pro with lifan 150, for now the mikuni (copy?) vm24 which came with the engine. When the break in period is over, a keihin pwk28 is waiting on the shelf and will be used with a takegawa manifold and K&N filter(which i still have to buy)

Genuine Mikuni's are stamped on the intake side either on the intake spigot itself or on the housing depending on the carb.

Excellent! You Euro guys have all the good stuff!!! No fair...LOL

Those parts are also available in the states. (just ask Z or Brad

)
(or are you referring to the skyteam bikes, yes they are road legal overhere.

)

muxster · 02-26-2009, 01:38 PM

what I meant is that everytime I see pics of bikes in UK and Europe they all have Takegawa Motors etc.

WE ARE POOR IN THE STATES....MATES!

muxster · 03-02-2009, 02:02 PM

If you're buying a carb you're better off sticking with a genuine Keihin or Mikuni, as it will always run better than a clone carb!

Even if your engine were to expire on you, you've always got a decent carb for your next engine or project.

Another carb worth considering if you're looking at 28mm is the Keihin PE28, its a round slide similar to the Mikuni VM's, fairly easy to dail-in, I think one would would go very well on the Lifan 150!

Thanks. I am looking at a VM28 carb kit right now with Manifold and jets etc. Round slide will be better than Flat slide for a guy like me.
