Its one carb for left and one for the right side......it took about 15-20 secs for the top cyls to fire once it started. It took about 3 runs to get a similar mixture running from both the top and bottom pair of cyls..... I think the difference between the pairs will diminish once the engine starts to run at higher speeds and gravity stops playing its parts. Ill post up some pics of the engine shortly...

Cheers
Mick

Nice. Can't wait for the operational verdict.

BTW, I am still in the market for a visually and dimensionally accurate 1985 YZR500 OW81 frame (or perhaps a 1984 OW76 frame) ... do you still take on custom frame commissions?

Thnx Jeff......RC45, I'm still doing one off frames, although the the last few yrs have been mainly complete bike jobs. The 85 YZR is different with its extra square tubing hanging of the spar... Could be an interesting project
Cheers
Mick
