I called up SUDCO this morning and ordered Mains #185 and #190 Pilots #30 #32.5 and #35 Should have them by end of week. I will put them in this weekend and make a few more test runs. I only bought the cheap amazon ones to kinda get a ballpark range before buying the Mikunis. Was like $10...

UPDATE 03/30/2024 So I decided to put in #190 mains and the #30 pilots. Bike started great and ran smooth at idle. Took for test run and it still has some slight hesitation from 0 to .25 throttle and some very slight bucking when letting it engine brake with no throttle. Figured I’d go up to...

Am I good with those or do I need to adjust??

Ok pulled 1 carb apart tonight and this is what I have Slide - 2.0 Screw Jet / Needle Jet - 159 P-6 Don’t know what it means 😂

I’ll get the info tomorrow and post.

Yes have filters on it. They seem to be the K&N filters that come in a kit. They do not block the air passages on the filter side of carbs. Where is the needle jet? I only see the pilot and main inside the bowl section? Slide? As in throttle slide? I didn’t know there were options variants on...

Yes they appear to be the barrel K&N ones that come in the usual kit. They are clean and they do not have a lip on them blocking any ports.

Are you referring to the round slide?? I don’t know. Is there a model number on it? I was assuming all VM-34s had the same slide in them. Have not checked needle jet. Don’t know answer to that question. Will look tomorrow.

UPDATE: Upped the main jet to 180 and upped the pilot jet to 27.5 today. Bike ran a bit smoother but back fired at times. Still has a dead spot between 1/4 & 1/2 throttle. Bucks a bit and then the power comes on 1/2 throttle and above. Stumbles when off throttle and letting engine brake bike...
