I may possibly keep the diaphragms from getting holes worn through them. It can't hurt.It seals very well and appears to make the diaphragm soft and supple .....
I'm keeping this in mind. I ran the bike about 20 minutes, with probable 10 being at 60-65mph and it felt okay at the higher rpms. When warming up and when coming off idle, it feels unresponsive and like its wanting to die on me. I am going to go back to the shim that I was running before yesterday because it was all aroundWhen it comes to carbs, you best bet is gonna be sticking with factory parts.... Mikuni in this case. That Mikes kit uses Chinese repops, not Mikuni. Look for Niche Cycle for OEM Mikuni parts.
Is the plug over the mix screw removed? You'll need to be able to adjust them to fine tune it. Give us some pics of the top front of the carbs if you're not sure.
My 34's had the same flat spot off idle. Going up a size or two on the pilots helps.... what fixed mine was a small (3mm?) washer under the needle clip to raise the needle slightly. I you can't find info on that, let me know and I'll see what I can find on mine.
I had fine movement with 2 washers. Ill probably pick up 137.5s and some 140's as well. Gonna go back to the previous washer setup here in a minute once I go to lab.Maybe 137.5 main jets at some point. If the jet needle has up/down movement with 2 washers it's ok. If it's bound (not moving) only 1 washer is possible. Or, you can go with a 336-Y-0 needle jet and a 51X11 needle set (richer) and then start over on main and pilot sizes

I see. Ive been messing around putting washers in all the places for the past couple days and I definitely "fucked around and found out" for myself with the two washers under the clip. Im running it currently with no washers under the clip and that seems to be working. Just to make sure I am understanding this correctly, placing washers underneath the clip will richen the midrange, and placing one above would in theory lean the mix, but it actually does not do anything.Yeah I shoulda said that; A possible issue is stacked washers can/could make the needles bind, stop a slide from dropping, as long as the installed needle can be "wiggled a bit" it's fine.
"your washers might be thinner than mine.............."
Yeah I’m jetted up one size in both pilots and mains. Right now needle at stock height. Uni pods and 2 in 1 exhaust. I don’t have a flat spot off idle, but in the midrange I get a bit of hesitation. I just can’t tell if it’s lean or rich. Im guessing lean? Anyone have thoughts?This washer mod (first used by the KZ1300 guys) is intended as a quick and dirty fix for the early EPA carb lean stumble in a completely stock bike. It's just a little nudge, if changes have been made to intake, exhaust, engine, true jetting work is going to be needed. Why tuners have selections of the various jets in many sizes.
This was perfect and exactly what I was looking for. It’s definitely too lean in the midrange. Once I get to about 2500-4000 it wants to stutter quickly. My needle is stock, no washer. I’m going to pull my carbs and try to go one lolThe needle setting tends to show up as the slide starts to rise ie about 25-3500RPM
It's a bit hard to describe but a lean condition tends to act like a light switch, with quick on off stumbles. ut, ut ,ut. A rich condition tends to feel more blubbery. More throttle tends to make lean worse, rich better.
A lean stumble is literally a cylinder not combusting/firing for one revolution. ie; a misfire. Rich is so much fuel (a smoky fire) the cylinder mix burns slowly not giving the piston of good hard push.

Still too lean. Going to go up to 137.5 in my mainsG

So I did some digging and chatting with some locals at the shop. I’m running the Mac 2-1 megaphone exhaust. It’s got a baffle, it’s just still loud as hell.Lets see a pic or three, there was no factory "single exhaust model".
