I don't think I ever posted this, but this one rotates and by taking the lower bracket of you can split the case.

Really appreciate this! However after being nominated last year and making it to the calendar, I don't know whether to accept, I guess other bikes deserve a change first? And secondly I didn't really change all that much this year....

Haha this was a day trip! This was with all that I bring. Been fine tuning this for a while, although for another bike. But I got it down to just a roll and a tank bag.

Did a 2400km camping trip to France, Germany and Luxemburg. Was a real nice week, met lots of nice people. Bike did great, only some small things 😂 ....broke the exhaust twice, lost some bolts, rattled the TomTom holder to pieces. The highway wasn't pleasant, I hope to improve the vibrations...

Just reading the general mikuni VM manual. Maybe its not super weird i dont need to use the choke (enricher) at the current temperature?

Before I changed the cam chain (to what I believe is the right tooth), I tried the VMs. I do remember they started only with choke. I to have two separate choke levers. And jerry from heiden tuning recommended using the chokes for starting. He prepared these carbs. I don't know what floats I...

Did some testing yesterday, it running great! The idle is really stable ones warmed up, which is nice. No more traffic lights anxiety haha. Did some minor tweaking of the mix screws and throttle slide screws. Only the cold starting is still hard. It doesn't accept any choke while starting...

Amazing, I love this forum. Yes, although if never been able to find it, I think this is it! I got the ones for the OEM CV carbs printed and this looks similar but for the VM. Thanks

Had some time in between the new shed project. So I decided to swap the cam chain. Since I had no shed it had to be done in the living room haha. The new chain went in smooth. Since I only had to take the valve cover off. We switched it one tooth. Since the guess was, that was issue. It annoyed...

But the new carbs are not the sollution to my issues.... Unfortunately. Installed them, and synched them at idle in order to proceed synching them off-idle. But I'm getting basically the same weird symptoms at idle as with the other keihin carbs.... Sometimes hard to start, might idle nicely...

The plastic injection moulded parts fractured. I got a new replacement. Also a realisation that this failure would be hard to repair on the road.

So I decided to go to heiden tuning for some support on the carb tuning. He was real busy and had no to little experience with the keihins CVK34. He recommended a pair of new mikuni VM34. Pre jetted for the XS. Since I got very limited time I decided to go this route. Hoping it needs minimal...

I'll try the lube First , much easier haha. About those butterflies. Is that when they are not centered properly? I never loosened those screws before.

There should be 2 springs. Just like Gary s picture. I can see I got two springs in there! So weird. Pushing on it closes the butterfly. Maybe when the idle is high, the play in the sync mechanism allows me to push and "choke" the RHS cylinder, resulting in the idle dropping faster. This should...
