What is the sound of one piston slapping?

I know nothing about them!

I want to get the CB-1 up and running again. At one point a couple years ago I had it where it would start, but idle was sporadic and it would fall on it’s face above like 1/4 throttle/5k rpms. I’m thinking it was bad gas and maybe the carbs need to be cleaned out?


I was also browsing craigslist and by chance stumbled on someone nearby selling a Kerker exhaust system for the bike! It’s a rare bike so this is unusual, but I think I’m going to get it. These bikes run slightly on the lean side stock, and a pipe isn’t going to help that, so since I need to fiddle with the carbs I’m going to order a jet kit for it.

Any advice? Suggestions? Has anyone dealt with carbjetkits.com? They sell motorcycle jet kits and you can even put in information about your bike and they will suggest kits. Their recommendation for me was #38 pilot, #110 main, 2 shims on the needles. That seems to check with what I’ve read in some forums and such.
