Buat sdri ke pomen buat ni? Angin buka berapa? Takuk jarum pin?
Plug hitam smua kn? Kalau pakai carb Uma Racing standard plug mmg susah nak dpt perang, msti kaler gelap.. Carb set utk speed je jln taman or town xley layan slow msti semput2.. Adat tradisi carb uma, bertuah siapa dapat plug kaler perang...hehehehe

**Minta tulis detail sket, simple sgt ssah juga nk bagi cadangan...Huhuhu
pomen sendiri je.. huhu
ok skang da besarkan sikit mj ..kaler koko kehitaman sikit..
mj 110 pj 32
jarum takuk tgh
angin buka 2 stgh
jalan biasa ada bobok2 sikit :mad::)
