Hi everyone, im wondering if anyone has any information on the differences between the techno and evo. I've reverted to using a evo manual to rebuild my 98 techno engine due to the case and internal similarities. Are the cranks the same for the evo 250 ? As I'm struggling to source a techno crank rebuild kit, and hoped maybe the evo kit will fit,?

The keyway on the Techno crank is in a different spot.    the con rod kit  part number you are looking for is   11.03720.800       I think this is what you are looking for

I just wondered if the evo conrod kit is the same butt.. techno kits are rare and pricey

 Pricey means you should buy before they are obsolete or part out the bike.

Are the wrist pin, big bearing and conrod the same for the techno, and evo due to the engine being identical?

The engine is not the same. There are minor differences.
