Exhaust flares????

Who's GOOD at welding cast block's together?

The answer to that question would be "Allen Millyard".

The man lives in England and makes multi-cylinder conversions of various bikes. Click on this link to see an example of how he does his work. He will turn 3-cylinder Kaw 500s into 5-cylinder 833s. He has also turned 3-cylinder 750s into 4-cylinder 1000s and 5-cylinder 1250s.


His latest creation, though, has to be his crowning acheivement. It took a LOT of work, but he converted a Kaw 1300 into a V-12 2300. (He had to de-stroke it a bit to get clearance for the new graft.) He stretched the frame and gas tank 4.5 inches to get enough room, and had to rotate the original cylinder bank forward several degrees before grafting the rear cylinder bank into place. The rear cylinder bank is rotated so that the intakes of both banks are in the V (like most V-Twins and V-Fours) and it has four separate 3-into-1 exhaust systems. Since I had one of the original KZ1300s, I was really impressed by how stock the new bike looks.





He also has done a Kaw Z-1 (900cc) into a 1600cc V-8. I saw that one at the Barber Motor Sports museum, but don't have that picture available to post.

Fortunately, it's fuel injected. Still, ratios had to be ironed out, but at least they should stay that way.
