Thank you for the quick reply, I have had this bike for a few years and really want to ride it only to get it back and learn that the carbs are bad. Rocky point cycle has an already upgraded kit that should just go on my bike that is a CV. From what I could find i could only find 2 bing carbs for 100 less that may or may not work and that is why i was thinking of the mikuni. Also the bing carbs are for a r90 and would have to be adjusted, and i am not very good with.
Hmmm, bad Bings, eh? Bad because your bike doesn't start or run well? Or bad because they have some terminal problem that would cost too much to fix?

But it's your bike and you get to do what you want to do with it. Here on this forum we don't have any originality police. It's what floats YOUR boat that counts.

So I gather that you have found a Mikuni kit that comes with everything you need--including instructions on how to install the kit and what the initial settings should be for your configuration, and tuning advice? That would certainly make things a LOT easier. Or perhaps you know somebody who has already done the mod that you're wanting to do. Perhaps Rocky Point Cycle? Are they promising to help you when questions arise doing the mod and when fine tuning the carbs?

@logangranson, we'd like to know why your carbs are bad???

the 75/6 and 90/6 both use 32mm Bing's. Jetting might be a little different.

75/6 carb is 64/32/13-14. main jet 145, needle jet 2.66, atomiser 591, needle pos 3, idle mixt @ 0.5 turns out.

90/6 carb is 64/32/11-12. main jet 150, needle jet 2.68, atomiser 591, needle pos 2, idle mixt @ 1 turn out.

Maybe check what you've got inside your carbs.
Cheers, Steve

And go to Bing Agency, USA, and get their $12 manual. No brainer.

^^^ yep, that's value for money and in the long run can save you money as it allows some learning, enough to bypass the occasional expensive mechanic.
