YOSHIMURA MJN: THE GAME CHANGING CARBURETOR ???????

Fascinating stuff,thanks!
The vintage custom superbike market is huge in Japan, and may gain some more ground here.I just looked through the latest Sudco dealer catalog, and they have the most vintage bike parts they have had since the late 90s.
Hopefully, since my CHIKN is close to 20 years old, they will develop needles and carb parts for it as well.
Be great to get more power and better fuel economy out of it with this concept. Factory Pro at one time had dispersion needles in development for them, but I think they have fell on low times.
Fingers crossed!

This is precisely what led me down the road to the Factory Pro HDJ needle jet. I stumbled across the MJN and, after doing numerous Google searches, realised it would be impossible to find an MJN needle for our carbs. However, the HDJ, which does essentially the same thing (ie. create a highly atomised fuel mist) could be a potential option. Sadly, I am still waiting to get my HDJ-equipped carbs back from FP to put the theory to the test...

Not available for Superhawk. Boo. Check out the double velocity stacks though - now that looks like a project we could handle
