If you need to back out the pilot mixture screw (the awful screw under the carb, near the intake tube) more than two turns to make it idle, you need a larger slow jet.

Try to find an assortment of jets on eBay, so you can easily change them to whatever you wish. I follow the tip of another rider on this forum, and write the jet sizes on the bowl with a Sharpie.

OK will do and thank you. Do you happen to know what jets the mikuni comes with? I will p!ay with it this weekend maybe. I work morning to late afternoon all week and unless I do it early its just to freaking hot here. When it's bearable, its too dark. No garage. But thanks as always.

100 main and 20 slow. Probably about right for 150cc at sea level.

Weldangrind · 10-12-2015, 06:43 PM

BTW, the main jets are officially called N100.604, and the slow jets are VM28/486. That may help in your eBay searches.

Just unbolt the carb and take it inside the house.

Thanks. Very useful info... as opposed to my method of getting the micrometer out and measuring the dang things... always the hard way...

So after waiting a week, the black plastics for my hawk finally arrive. But when I open the box I find that the plastics RPS shipped were for a completely different motorcycle. I will contact them shortly. I really hope they can resolve this for me.

Well, that's no good.

I didn't ship them so I don't know what happened. We have all the parts though, just call back.

I'm glad you're here, Adam. I suspect your presence will help several riders.

A note to the jet drillers: if you go to far with the size of the drilled jet, just solder it shut and start over and don't use the last drill that made it too big!

I had over 5000 miles on a soldered jet when a dog got under the front wheel and wrecked to scooter and at that time it was running perfect.

Use the proper stuff http://en.wikipedia.org/wiki/Solder as possible. Higher tin (Sn) = Higher tensile and shear strengths. Pls leave those good old 60/40 | 63/37 to electronic components ONLY. Lead-free is good for electric wire joints & "this" jet repair.

Weldangrind · 10-18-2015, 12:01 PM

So, lead-free and high tin solder for brass carb jets? If so, I suspect that plumbing solder would also be the correct compound, except that it is too large to work with.

jct842 · 10-18-2015, 06:54 PM

I do not remember what I used, either 60/40 or 50/50 is what I normally have in shop but it did hold up well and seeing that solder is a temp solution to find what you need to buy for jets. I just kept drilling bigger, got impatient and skipped a size! Never did buy the correct one but I was thinking about it! john
