are these kk barrels or possibly a good hoe tuner ?

looking at the cut out fins for the mag and the narrowness of the valve seats.

Re: hi are these kk cylinders ??

I don't recall the KK or the KHK having a magneto. I recall them both being hotrod street bikes with circut breaker/coil/battery ignition setup.

KK cylinders would have highly polished ports. And no magneto relief from stock. All KK engines were points ignition.

Re: hi are these kk cylinders ??

Hi all,

AFAIK, KK and KHK only had bigger reliefs in the heads for extra cam lift clearance, no special polishing jobs on the cylinders.

In later years anyone could have mounted a Fairbanks Morse on a K or KH, there's no need then to trim the cylinders.

Which makes me thinks these are KRM cylinders since KRM and early KHRM were fitted with vertival Wico mags. These are so tall they indeed required the fins to be trimmed by the factory...

Re: hi are these kk cylinders ??

I believe both the 55 and 56 KHK had polished ports (and polished external surfaces of heads too).

Re: hi are these kk cylinders ??

Speaking of pictures, could someone show me a clear picture of the top of a k or kh barrel and combustion chamber of head please. I'm doing some surgery on a BSA M20 sidevalve and need some clues. Of course i could ask my mate to take a head off his Kh but i think that's asking too much!

Re: hi are these kk cylinders ??

Thanks Jib, A dremelling i go! I have about 5 spare heads and barrels to play with and these motors are a dime a dozen down here as they were also used for industrial purposes as well as bikes (gutless)!Any more clearer ones of the heads would be appreciated from anyone. Thanks!
