Mikuni and Keihin numbers represent volumetric flow rates for a given pressure difference across the jet. Mikunis are cc/minute with 50cm of (gasoline) head pressure. Not sure on Keihin's units. Dynojet numbers are a function of hole diameter and have nothing to do with flow rate.

Who needs Google Looking on the Mikuni thread (good idea btw) the r100s are running 190-200 mains and the slow jet is around 30. I'm not seeing those on the list. It was worth a shot at least.

Well, a Banshee is a 2 stroke and only 350cc (so 175cc per side) and since 2 strokes run so different than a 4 stroke, I am going to say this should be way fun! I am going to go out on a limb here and say slap em on and see if it'll run! What is your altitude? Close to sea level yes?

I'm already on that limb

I've got to get the throttle sorted first. I have a repop Triumph twin-pull right now. It routes the cables straight down from the bar leaving them exposed in the woods. I bought this for the Keihins to run the cables behind the headlight:



The eBay ad said this came from a Kawasaki but it didn't say which one. No idea what to do for cables.

When I ditch the choke cable I can toss the clutch perch with it. The light switch hasn't worked in a while. Any recommendations on a new one? Anything that fits the old cable would be fine. Don't really care what it looks like.

I'll bet Rocky Point can fix you up with cables. I mistakenly have a set of cables for an R60 that might work if that's any help (small barrels on both ends)...I got them before I realized the R75 had different ends.

+1 However, if you're worried about changing the main over and over, there is a plug on the bottom that allows for access to the main. Mine is a 17mm
You're right, these are the same way. There's a big plug on the bottom of the bowl and you can change both the main and the pilot jet through it. That's going to make this a lot easier.



Skip ahead to minute 5:10. The guy made a float level gauge that I NEED to make.

This is like waiting for Christmas. I've got class next week then Spring Break. Hopefully I'll have all the parts in along with an idea of what jets i need so I can get these sorted out while I have some time off.

Oooooh, that's what 'quad vent' means! And they had the good sense to make them pink.

I bought half of a K&N intake kit for a GSXR. I had to match the muffler ya know The flanges have the same OD, 2.5", as the carbs so some rubber tubing from the hardware store should set me up for cheap.



I've got Spring Break week after next. I'll probably do a tech day on one of those to get some of this sorted out. Lemme know if anybody's interested.

I'm having a harder time finding 2.5" radiator hose than I expected. I spent yesterday roughing in the exhaust since I can't do anything to the intake until parts come in. This is all 1.5" SS tubing. This project snowballed fast.

Geeze, man. Whats really a bummer is that between Fred and I, we have a nice selection of Mikuni TM/VM pilot and main jets.....about 150$ worth. You hopefully can find a "tune up" kit for the Kehin and get a deal on jets.
