So I thought this might be a decent spot to ask.

I'm wanting to do the swap on my R75/5 and I'm curious about what throttle/cables I'd need.

It's got the "US" bars on it now but I'd like to make the switch to Euro's. For that, what cable lengths would I need and will they work with the stock throttle?

As well, which bore is best for just commuting/touring a little? I'm thinking 32 would make sense, but I don't get why folks are using 38's and such.

I think 32's will work with the stock throttle cam.

Ooh, glad I found this thread. I am very soon to be putting some mikuni's on my 71 75/5! Except that my /5 has r90s heads/cylinders/carbs....I'm thinking of getting the vm34's, but my concern is cabling? Where are you getting your cables from, or are you using custom kits?

Just saw I'm repeating a question somewhat. I actually have some old Honda bars on mine now, but I'm thinking of getting the euro bar as well.

I bought my cables from Bill at rocky point cycle and they are a thing of beauty!!! Very easy pull and easy to sync with the inline adjusters. I highly recommend that route vs bodging route, which I did initially.

Already have the Mikuni 32 kit installed on my 72 R/75, love'em. Now I'm thinking of a set of 36's for my newly acquired 78 100RS 40mm exhaust, I did not see that size available at Rocky Point. I might just call them to see if they can make me up a kit, I agree their cables are great, you can really fine tune them.

I was under the impression that Bill, or was that Stan, had sold Rocky Point... I may have to check them out after all! Really looking forward to getting these del'lorto's off my machine!!!

Oh, and quick question, I assume there is no left side / right side orientation on the carbs, so are adjustments hard to make on one side vs. the other?

My Rocky Point kit is left and right. The hard one to get to is the left side air mix screw which is necessarily in the same location in the carb body and doesn't transpose.

I'm still struggling a tiny bit with the choke cables but the throttle set is spot on.

My Tm's are not left, right oriented. But I don't believe Bill sells the TMs, just the VM's. And yes, Stan sold the operation to Bill who is just as big a carburetor nerd as Stan. Loves to help you tune them over the phone, and hear results!!!

140's and 02's now with 6f4 "even" needle.

i will try a leaner jet needle and see.

runs very smooth and less burbling at the bottom.

Please try to include your slide angle. When starting from scratch. It makes ALL the difference. Same with needle jets.

I committed. I'll be running vm32s on the r90/6 as soon as they arrive.

I'd like to keep the stock air filter and box setup so that will require some creative engineering. I'll post what size components are in the carbs as well as how it goes when all is assembled. I'm sure I won't get it right at first.
