Does any one have any idea where i can get this done or buy the bits to do it? I need jets 1 size larger (need 118 & 38 for CBR 150), but CNX is a no go, tried around 6 different shops. I can get them in BKK but don't want to make a trip for a 100-200 baht part.

So the only other option is to drill the jets out.

thanx !

Drilling is a no no.

Get them sent by post from BKK.

Have you tried the shop at Chang Moi, pass the "helmet shop and over the small bridge, then on the left side at the corner there is a shop that sells, make all kinds of modified engine stuff.

hi Semper, yes i've been to those shops, they have jets for the NSR carbs but not for the stock CBR 150.

either drilling them or if i can find a set of jet reamers.

Can't a Honda dealer order them for you? BTW. I'd go 2 size larger, 1 would be same same.

Nope, i tried at Niyom and Sangchai already. People usually go up to the NSR carb for mods, but i want to see how far i can take the stock carb.

Might try Nat motors on Huay Kaew, i here there's a mechanic there that likes messing with the CBR 150.
