big papa what is the ideal jettings for the uma carb 28mm (open carb)?? TIA..big poppa said:Pm'd you bro.
papa big tnx for that info.. currrently im using a 102/38 jettings on my 28mm open carb & it works for my setting..big poppa said:Bro my basis is Keihin PWK Which is my carb.. But, I guess since they say that UMA is design 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?
