hey guys, i bought this bike, its a 93. its suppose to be 30 bored over.
Guy told me the carbs where jetted.
It came with a 2 sets of carbs, i ripped one apart and it had

138,132,138,132 injectors. with a weird symbol like the alpinestar star.

and the other set i only checked to but it was.

XXX,XXX,180k,180k, and the two 180k ones said factory.

Was wondering what the stock jets are, how these jets are read. and i read it should be (using the first set)

138,132,132,138 or 132,138,138,132

I dont know much about carbs, so any help would be great

Thanks

Welcome!

Not sure about the stock jet sizes for a 93, but the correct reading should be: 132,138,138,132. Normally the two smaller jets go on the outside two carbs (#'s 1 & 4) and the larger one go in the middle two (#'s 3 & 4). The middle two get bigger jets because they typically get hotter than the outer two.

Someone will be along shortly to expound further on 93 jet sizes.
