That Mikuni looks like the first one I got when I asked for a Deni or Kehin 125 main jet. This was before I even opened the carb. My main is definitely one piece. Whe I look at it under magnification I can see a radiused shoulder where yours twist apart. Can I get both parts? Seems more flexible (and probably cheaper in the long run) that way. James??

When this lousy weather breaks I wanna ride!

We have had a few calls here from people who have pulled out the whole brass piece insted of the center jet, so, I am posting some pics that I hope will be helpful to some.

I checked the Yerf manual and you have the same type jets. I'm pretty sure you probably just unscrewed the whole piece. They can be pretty tight.

good luck,

I figured I had nothing to lose so I reefed on that little bugger & it popped loose. I have the same jet afterall. I still don't know what size it is--it's not marked--but a #57 drill will pass but #56 won't. That puts it about .044". Checking my handy convert-anything program a .043" = .110cm. I wonder if that's the numbering trick (centimeters)?
Guess I'll have to go back to the cycle shop yet again. If that doesn't work I'll be giving James a call.

Thanks again for all the help. The pictures are worth their weight in gold.

Great pics STU... thank you for that.


Some reason the "keihin with jet in" photo doesn't show up in thumbnail form... I tried editing , but to no avail. Must be some sort of bug.

I tried too but if you click on it it shows up, I think the pictures came out pretty good though.

stu

Yeah, I know it's clickable... just thought I would mention that because some people may not realize it's there. It is a great shot, you photo guru, you. You sure you're not one of the photographers on your buddy's web site there???

Mark,

hit it carefully with the #56, make sure not to leave any shavings at all, this will give you a 127 or so jet... will do you good until you get some jets in, we have some karts that we run this way and never added a new ket, no problems!!!
