crazzy #1 · Sep 17, 2006

if its the right sized jet now you wont get any performance but if it is slugish and hezitant on hard acellration then you could probly do wid it.

I think dhz has those bikes overcarbed. I have an as new standard 25mm mikuni for that engine if your interested I will do a swap.

why would i go down sizing? im not having a go at you, just saying...

dude that aint a genuine 26 mm mikuni. Its an oval bore 22-26 mm carb. They are ok for most china bikes but need proper set up to get the best out of them. As with most people who know absolutely nothing about carbs and jetting you have touched on a common mistake that Bigger jets mean a faster bike.WRONG. If the jetting is wrong then proper set up will make a difference. sometimes a smaller jet will work better than stock. Just thinking by putting a bigger jet in will make ya bike faster is silly if the bike cant handle it. The best carb to use on most china 110 or 125 is a keihin 24mm round slide.

mack, is the 25 genuine mikuni?

Mack · Sep 21, 2006

yep, I'll just send it for you to try if ya want. If its no good just send it back.

crazzy #1 · Sep 22, 2006

sounds good... id like to try it... but what if i was to keep it, send you mine, then end up boring etc to my bike, would i be able to get it back?

Mack · Sep 25, 2006

You will only want to go back to the bigger carby after boring, hc piston, big bore exhaust, and porting has been done. If thats your intention, then hang on to it.

Mack, a while ago a guy on another forum said that he had been in touch with mikuni and was told they only make a 26mm and 22mm for these. Is this true? If u could measure yours it would be good to know.
