34L / 2KF engines - what's the difference?
 

I am starting a repair on a '84 XT600 tenere with a 34L engine.
The gearbox has an issue with selection of 3rd gear.

I have 2 bare (no cylinder/clutch) donor engines, 1 x 34L and 1 x 2KF.

What I need to know is - are there any differences that could cause me problems???

Thanks Tom
