Mikuni tm36 jetting

coldfish · Mar 12, 2023

Hi, I have an old mikuni tm36 which I’d like to try on my 750 commando. Does anyone have any base line jetting suggestions? It has no idle adjuster screw fitted, so I expect I’ll have to adjust the idle with the cable adjuster? It’s a non pumper carb. Thanks

Thanks, but that’s about mounting the pumper carbs. I’m looking for some idea of jetting. I have a number four slide and I’m guessing I need a 389 p-0 or p-2 needle jet? Maybe a 6DH3 needle? 240 main? And 35 pilot? These are mostly from tm34 settings and I’m wondering how much these would change for a tm36?

Thanks, but that’s a vm, I have a tm. Maybe it’s similar jetting? Anyway it doesn’t give jetting…

'Because I can' is never a good reason for doing anything. Only the best is ever good enough. Cheap always has added expenses.

I have a TM 40 on mine
You may have to notch the frame gusset to make it fit
My frame has had the gusset removed so no clearance problems there
I had to change the needle jet and main jet to get it to run right
It gives fantastic mid range and top end unlike a single VM mik

Yes.. that was the point for my first posted link (clearance issues for that instrument)

Hi, thanks, I‘m always a bit reluctant to ask if I haven’t bought the carb from them. Maybe I’ll drop them a line…
