      The fitting you are talking about is the pulse line for the fuel pump. I run a Dellorto and go straight off the Mikuni round pump to the inlet. Other carbs may vary.

      Water wetter is fine.

      For the intake boot and clutch part here’s the secret. Search ebay for ATK 250 as this engine was used on ATK dirtbikes here in the states. I know there is a boot and clutch cover there right now. As they have been listed for some time you might want to deal with the them for a better price. It worked for me on the couple items I needed for a spare motor.

      These are strong little motors and last well when kept a little rich. Shift gently and take care of the gearbox as gears are expensive and at times hard to find.

      It’d be easier on the gearbox if I can find a way to reinstall the clutch! :) Thanks for the tips…. keep ’em coming. ~Ted

      Dennis does have quite a supply of Rotax stuff and is a pretty good guy to deal with too!

      Thanks, Dennis…. I’m going to look through my spares to see if the clutch cover assembly is in there…. It’s going to be tough for me to tell what the spares for the 2 “free” 125’s I got are and what’s for the 257. I will try to post pics here.
