Has anyone on here run one of the "Yoshi" carbs yet and what's your experience? In comparison to the Mikuni's, what's different and which do you prefer? Thanks

Hands Down the best damn carbs ive ever worked with.

Im running a Yosh MJN-TM24 on my 95cc motor and a MJN-TM26 on my 115 ape.

I posted a thread a while back with my experiences with them. I think TMAS has one of these carbs now as well.

The MJN design places small holes along the sides of the hollow needle to atomize fuel at the center of the carburator throat which is the point of highest intake velocity. This provides improved throttle response and horsepower at low and mid-range rpm. Peak power is also higher because the main jet is allowed to flow more fuel with less restriction. The pilot circuit is stopped when the throttle is closed in order to prevent run-on which keeps the combustion chambers cleaner.

the carb is also thermal transdusive coated inside and out to reduce heat.

absolutly THE best performing carbs hands down. Easy to tune and make great power. I run a 24mm a 26mm and have a 24mm bored out to a 28mm and they all work perfect. Well worth the money.

Grafixxs · 01-15-2009, 01:58 PM

So now the question is, where to get one of these carbs? I assume the 24mm will work great on a 88cc as well?

HymieP · 01-15-2009, 02:00 PM

Thanks, I think I'm going to go with the G-Craft intake with the swivel also. Pics would be great if you have them. Thanks

HymieP · 01-15-2009, 02:02 PM

They say they work great on anything over 88cc. I'm still learning everything I can about these, but so far, they sound like "the" carb to run. Easily tuned which is what I am after.

HACKMUNCH · 01-16-2009, 07:07 AM

i have 2 of those carbs, they are just tm28-1. the accel pump works killer, throttle response is snappy to say the least. IMO they are the best carbs i have used.

They are different. Yosh buys the bodies from Mikuni and the internal parts are redesigned by Yoshimura. Different animal.

its no just the different needle. Its just the whole package works better all around over a standard Mikuni

HACKMUNCH · 01-16-2009, 07:41 AM

what can they change to make it better if the body is the same, i see they change the needle but what else?

p3racer · 01-16-2009, 07:45 AM

I know it has less vent hoses hanging from it and uses a different style jets than the standard tm

Spend some time reading up on these and you'll see the differences.
