Engine Needed

[iscqda]

Hello all

Bought a 1975 registered 750 K2 (UK model i think)      Engines was in bits but is not original to bike   - I think it is off a 1978 model    Does anyone know of an earlier engine for sale please -  looked on ebay and unsure about condition    thanks

Tell us your VIN so we have an idea of Engel number range requirements?

If registered as a UK 1975 it will be a K4 engine  The frame number can be as late as 21*****

Yes  thanks for replies folk   -  VIN Frame starts with  210......     I think looking at John Wyatt's restorers guide the engine should be K4 range 2300001 - 2372114 -
