I used to have a really nice Snap On set, but it has wandered off over the years. I could even soldier the opening shut and try again if I really screw up. The results speak for themselves - with over 40 million customers and thousands of people switching to Harbor Freight Tools every day. I drilled out the pilot, main and secondary. Not saying it couldn't be done but certainly it isn't all that easy to get right without the correct set up. I have to say this made a huge improvement in the bike.
I just wanted to tell you guys that I did this and that it made a large difference. Keihin jets are numbered different than Mikuni, etc. Unless someone on here has done the same as you it'll be trial and error or throttle chops or dyno runs. The flow rate is only partly affected by the Diametter of the hole but also by the length of that diametter. This drill bit kit has many applications.

Jet drills allow more sizing options in between jet sizes. You will need to purchase the right sized reemer,and undersized drill. I don't know why this rumor persists, of the orifice diameter being other than hundredths of millimeters, but I can't find any that are different from hundredths of millimeters.
You can buy any jet you want from Sudco, they have everything in stock. I just wanted to tell you guys that I did this and that it made a large difference. I replaced my stock exhaust for supertrapp exhaust. I didn't have the absolute exact size I needed for the pilot jet. When you embark on the modifications you plan to make; take every precaution not to damage the Stock Parts you remove in the process. I need to know wat 0. I had no problem with burs and the amount you are enlarging the holes is very small.
The one I use is. You need to know what sizes those homemade bits are! In some cases there were no other size jets available, especially when a new jet series first comes out. That is the only mod I have done. The most important part of the kit was not the jets, but the needles. Now the question is: should I go for 123 instead of 122?

I need a 92 and a 70 jet size and I am not sure I can drill out a pilot jet but if I can I need to know what size drill a 36 jet is. These are the smaller size drill bits used for gas clone engine main jets and pilot jets of Walbro carburetors. Or I could use the jets that I have ordered when they finally come special orders take time. It only took me one days worth of adjusting to get the bike running like I wanted it to. Always follow all of the instructions and warnings included with our products. Are they millimeters or just some arbitrary numbers? Be sure to mark the jets with a number stamp or engraving tool.
You will probably have to do some re-jetting and possibly move the needles. Now that it's breathing out better, you'll want it to be able to breathe in better too. This kit provides Jet Reamer sizes from 0. I had no problem with burs and the amount you are enlarging the holes is very small. Any who i digress i now have a problem with at half throttle it chokes itself out and chugs and pops, so know i reckon i need to bump up the pilot which is a 40 to like a 42 or something? As long as you are comparing similar type jets with similar orifice placement, they should flow about the same. The calculations calls to upgrade the main jet from 120 to 122.
