The overview of the carb.
This is the air mixture screw. Turn counter clockwise to make the mixture lean
Inside view of the carb, the half moon type
the set of pilot jet ( they dont sell per pcs one =.=)Well, continue with my Bike modification, this post will be talking about carburetor.
A lot of people don't know how to tune their carburetor. Is kind of hard actually but there few thing you need to know basically.
One, air mixture screw. Next pilot jet/main jet and last the slow jet (depending on your type of Carburetor.)
I convert my original jaguh carburetor to a UMA racing carb.
There are two different when change the carb, first more pick up. Secondly,more power. Well as you can see Modenas Jaguh is actually Bajaj Eliminator 175 but the carb jaguh using is Kawasaki Eliminator 125. So the size different is 2mm.....(that a lot, use area to calculate how much you loss) LOL. Bajaj Eliminator use 175 use 30mm carb. Kawasaki Eliminator 125 use 28mm (which is currently ours one)
So I decide to use 32mm carb.......It do take me a lot time, unplug, pluging and testing to tune the carb. But I'm currently happy with it.....
One last thing, start with rich mixture.....if lean you may blow up your engine. A simple rule, see your exshaut head for color scheme / spark plug for fast comparison.
Enjoy the pictures.

hi, i'm using a jaguh too, if your carb already using 29mm i think it's quite powerful already, for the top speed maybe u can try experiment with the spocket setting, i'm now using 15 at front and 38 at the back, top speed around 125-130kmh, maybe your front spocket is 14, try to use 15 at front...
Hi guys,
After few years using bigger/racing carb, how's your engine's condition now? any cracking, etc..?
I have 28 carb and 17 front, 42 rear. Top speed 105. Can I go faster using different reae sprocket?
Hi guys....when u change the carb how bike perform...
One more thing, fuel consumption is there any different when u change the carb?
Yes there will be different in fuel consumption. The more fuel mixture into the engine, the more ratio compression it would get. Then the pick up will increase and the fuel consumption will increase... :-D
Hi,may I know wat air filter u using?
