After a couple attempts with carbs on the new bike I talked to Chris Hodgson at SJBMW. He recommended a pair of 45mm Mikuni HSR carbs. I found a couple and went to the never ending job of fabricating parts for this bike. I had to make new intake manifolds. throttle cables and mounting brackets and air cleaner adapters. After remaking the fuel lines, I am ready for tests. The initial runs say I am finally getting all the power out of this engine now!
WoW!!
here are some pics:

No problem with the 45's so far. I installed the smallest accellerator pump jets before I even bolted them on and they work fine. The pilot jets seem to be the right size and I will put it on the road tomorrow to test the mains. They came with 175 main jets and that might be a little too rich but, there were no flat spots up to the redline just riding around the block. I wasn't able to hold it at speed for long so tomorrow should tell. I will run about 20 miles and come back and check the plugs.
Chris recommended the 45's because he has one with them on it. Says it runs great even at high altitude.
I guess I will bolt some wings on mine and find out
The motor started out as an 1100 and has been upgraded to 1150 with higher compression. It starts easier than FI with the enricher buttons pulled out. Once it warms up, even easier and finally a nice even idle. I had to shorten the idle adjuster and choke actuator. Both came as a long flexible cable attached to the carb.

I've gotta chime in here, this is a phenomenal machine. You've gotta be really proud of it. So many custom builds look pieced together, but you've done yours so well it looks like something the man upstairs intended all along. Beautiful.

Cheers!

I know this is a really old thread (just came across it for the first time while looking at stuff that was on this site before I joined in '08), but does anyone know what happened to this bike and if there is still a video somewhere where I can hear what it sounds like? It looks incredible!

Bryan,
I think rchop hangs out at the Motorcyclist Cafe web site these days. I haven't been there in a long time, but you might find more info there about the bike he built. A few guys from this board formed the Cafe forum a few years ago.

...does anyone know what happened to this bike...?
Perhaps contact Randy directly:

If I had the necessary resources, then I would definitely commission Randy to build my dream project bike!
