So I recently got rid of my stock bs38s on my kz750 twin and ordered the prejetted vm34s from niche cycle. My question is. The stock kz intake boots are too large to fit the 34mm carb inlet. Has anyone ever done this? I've seen people run the xs650 aluminum manifold and re drill the bolts holes a little more narrow to fit the kz but the manifolds don't have a barb to vacuum sync them. Is this an issue? Any help would be greatly appreciated.

Hey chopbobkz750, I run mikuni vm34s on my kz750 twin...

Yeah you cant use the stock boots... you have to find something aftermarket. I bought these really expensive anti reversion manifolds... i milled out the holes that they will fit the k bolt pattern... And synching isnt really a problem... once you do it a couple times you get the hang of how the engine runs best...

Check it... After spending a bunch of money on manifolds I decided to make my own... let me know if you want a set... The manis in the photo are just finished welded and need final finishing... thats why they look a little rough...

Cheapest, easiest way is order the intake manifolds from mikes XS
the ones for VM Carbs
Drill out the holes a bit to mate up to the twin and boom you're done
Literally just did this
You can order the 2-1 throttle cable while you're there, its a good price.

Also its cheaper next time to order generic VM carbs from ebay and jet accordingly
to get the jetting specs just search mikuni and your model of bike and one of the sellers will list what is inside the carb jet wise
go to the local bike shop, order the jets and save yourself $$$
