Just put a K&N into my 93 F2. now need to adjust air screws. I want to do it with the bike running so I can make sure everything is good.

Has anyone been able to make their own wrench, or know of a good place to get one $$$cheap$$$?

 

The pilot jet screws? You just take them all the way out, and then slot them with a dremel so as you can adjust them with a flat head screw driver. Screw them in all the way and count the turns out. 2.5 is stock I think, 1.5 is starting point for Dynojet kits.

 

they are slotted. Stock settings for my area (Calgary) is 2 turns out. she is rough idle, and when I am out on the highway holding steady at about 6000 rpm she likes to surge. I go to pass someone, she bogs down, then speeds up.

I cleaned the carbs, completely. The carbs are also perfectly synched, within 0.125 PSI of each other. the only thing i can think of is that I am running lean.

my only issues is trying to get at the mixture (pilot jet) screws while it is running. I found a tool, $140 and a week out. I would rather not spend that kind of coin, so if anyone has had success in making one please let me know.

I am currently messing around with a modified car carb. tool, still a little too tight to get it in under the carb bank.

 

Well... you don't have to adjust the pilot screws while it's running!

If they're already slotted, a flat head screw driver will do the trick.

this information is incorrect. your pilot screws need to be adjusted with the bike running. there is an entire procedure listed in the shop manual which involves observing rpm @ idle while adjusting the set screws. make sure that you have this procedure figured out before you start messing with the set screws.

 

I made one myself, but unfortunately the photo is on my digital camera memory card 250 miles away. I made a small tool on the lathe which is just a simple tube that fits around the screw, but still inside the carb's counterbore. Then I gently peened the tube with a hammer to form the flat spot.

You might bring the screw to the hardware/hobby store and buy some brass K&S tubing to fit, and then crimp it into the shape you need.
