Sorry wanted to share but didnt understand hehehe. Just in case you were looking for the Jettings for UMA, You could try out similar or imitation carb's jettings. Here in the philippines they have Imitation OKO Carbs, and the jettings for these carbs are equivalent to the UMA's and the Keihin PWKs Much cheaper compared to the UMA branded ones.

hehe,tnx 4 da tips bro,i speak my native tongue cos it is a country specific forum..Anyway,from what i undrstand,do u mean that keihin pwk's main jet kits are also compatible wth uma carbs?Cos i can see that they have da similarities in their looks..If so,how mch if i order frm u?

Bro my basis is Keihin PWK Which is my carb.. But, I guess since they say that UMA is designed or copied from PWK (Not sure) they may be similarities between the two.

Im using 115/35 Llucky MArtian (UMA) is 110 i think. Haen of indonesia I think also Uses 112 or 115 as main and 35 as slow/pilot (keihin PWK). How about you Bro The One?

huhu,today ive changed back my uma carb to stock carb..Cos i think due to improper tuning n the absent of the main jet kit,i just cant feel the desired performance that i wanted..Though,i satisfied wth the accleration,but when it reaches 100+ the engine just bogs down!I just dnt undrstand wths goin on.!So thats my story..Well,at least now wth the bike being installed wth the stock mikuni vm22,i can enjoy riding wth a peace n safe thoughts..Hmmm..No mo problem..I hope..
