I've got an 80' CB750K and really like the bike. Now, the 1st thing I'd do with that one would be to take that 4 into 1 off and just send it to me because it would obviously do MY bike MORE good than it would do yours!
Just kidding. Mine has the Jardine 4 into 2, but is a pretty good runner!
So, are you going for it? You WILL let us know, right?
Later on, Bill
