I sent my cylinder to kustom kraft to have it sleeved (just my personal preference) and they called me back and told me that there is no sleeve that will match my cylinder mostly because their are two EXTRA exhaust ports that dont exist on any other kx500 cylinder hes ever seen (and he has seen hundreds)and then he tells me that its a very very rare factory race team cylinder which is very likely the case because when i took the cylinder off it had no cut marks ANYWHERE it was totally untouched with no tool marks it looks just like a crude factory cast cylinder but with extra exhaust ports its pretty cool to have such a rare cylinder but now i cant have it sleeved because it will cost big bucks to have a custom sleeve made so i guess its back to plating. If anyone knows anything about it or where it came from please let me know i will also post pics of it when i get it back from plating.

cant see how it is possible to fit 2 extra exhaust ports on a kx ,89on already have 5 ex ports, even if was possibly there would not be enough piston skirt closing at TDC

I have been stairing at a K5 jug thinking the same thing also...
we have found how to cram 2 more intake ports.. But exaust... has got me...
RoostiusMaximus:
I solved the intake port :wink:
hopefully i'll find a chassis to get this motor into.
cobbs:
I'm just telling you what kustom kraft told me maybe he ment to say intake but he definently told me exhaust I don't know enough about the kx cylinder to to have known but he told me he tried every sleeve they make for it and none of them would work and I know he's worked on countless kx500s I just hope he didn't mess something up and is now trying to cover his tracks I know my cousin is a two stroke genius and he's owned a couple kx500s and he didn't notice anything out of the ordinary with my cylinder so I guess its going to be a mystery until I get it back and if it is a normal cylinder I'm going to be pissed off that he didn't sleeve it very pissed
kwakman:
why does it need a sleeve? Plating would be better IMO.
