hey all, im in this dilemma right now. Regulation change left us with air cooled engines completely obsolete, you can guess the stock of water cooled sudams wasn’t enough and now we’re in a situation where a water cooled sudam costs 3k-4k.
Im evaluating what are my options. Because the bottom end and crankshaft is the same for the air cooled engines, I can re-use them. and for the cylinder, I found someone who sells an X30 cylinder very cheap, and I have a few sleeves from the sudam, my idea was to use the casing and the sudam sleeve. The question is, will this hybrid work? The X30 sleeve has slightly different port timings than the one of the Sudam however.
my limited knowledge tells me it probably wont fit, but im unsure still. I would like to hear from someone who has had the chance to work with both engines, cause if this works then it would save me huge amounts of $$$
You could cross reference the base gasket part numbers from the X30 and the Sudam and see if they match. If they do the cylinder will fit the base, but no guarantee the ports will match up like Charles said.
I have seen some stuff from IAME cross between engines. For example, the KA100 ring gear will fit the MY09 crank with the newer style clutch shoe. Thank you Comet Kart Sales Guru!
