Can I use any carb model replacement engine? - SV650.org

Hi all,

Searched and couldn't find an answer so a quick question. I've found a replacement SV650S engine which I'm considering for my K2 engine which I managed to let run dry...

Can I use any of the carb engines as a direct replacement, ie. an engine from an X, Y, K1 or K2 bike? Having asked before I already know that K3> won't work because of the fuel injection.

yes you can, and with parts from your old one and a mod to negate the oil cooler you can also use the later injected one with your carbs fitted.

Cheers Mark.

Thanks! The K3> onwards option adds a bit of buying scope too!

saw a curvy at the weekend with a pointy engine fitted while i was picking up an engine, guy said that he actually found the curvy engine pulled better than the pointy with carbs fitted-weird?

The injected motor works very well in the carbed bike, alot of minitwin guys run injected motors in their carby bikes, the motor loves the carbs. I have a very good injected motor for sale, it may be out of your budget though but has had over £1000 worth of full refresh work done on it as it was a spare for our race bikes but never got used.

I assume that when you put injected cams into a carby engine you are doing the same thing (accept for gear select changes K5 onwards)?

Do you use the inj airbox or do the carbs / tank not fit?

Are there any other changes to the engine in inj trim with carbs?

Thanks for the info. I did look at your ad and it sounds great, but my budget is a lot smaller I'm afraid.
