I have an RM that has been restored (more cosmetic than "race prep")
It's had a brand new Mikuni VM32 slapped on it. The jetting is obviously generic, and not that close to that listed in the owners manual. I haven't run it in anger yet due other issues requiring attention. See "more cosmetic than "race prep".
I was planning on trying to get the original setup (found the original needle at Suzuki Parts), 2.0 slide available locally......
I figure this would be a good starting point?
Another option (recommended by the Aus Mukuni guy) would be a 35TMX Flatslide.
Although not 1981 kosher, the Flatslide would be legal for pre '85, the class I'd be in?
(New to VMX, plan to race it a few times at least before I hang it on the wall to remind me of when I was faster - ie 1981
)
I have a "works rep single sided airbox" on the way, so some fine tuning will be in order whichever route I go.
Comments and suggestions sought.
