If you can't find any secondhand ones.
Try Allens Performance (01949-836733) they stock all the Mikuni main jets & pilot jets - got all of mine from there

Are Dynojet mains compatable with standard Mikuni mains ie are the stamped sizes the same measurement .
I have a few sizes of Dynojet main jets but they are slightly smaller physically than slotted Mikunis .

Z1parr,
There is no direct compatibly with Dynojet to mikuni THAT I KNOW OF.
I have been told that Mikuni use a flow rate & Dynojet use a metric size....
If this is not correct, I am sure someone will jump in & add.
All I know is that I have dynojets in my 1974 VM28
I found this web site - might be helpful

Thanks Stu , what a world of arseing that is eh
The table of flow to diameter doesn't run linear just to upset things

I've had excellent service from this lot, genuine Mikuni jets are around £2.50 each.
