Just bought a WR400 - hesitates when throttle opened

1 post in this topic

Hi all - just bought my first real 4 stroke this afternoon after years of 2 strokes.

Goes well but hesitates when I open the throttle. The guy I bought it from gave me a thing with pipes coming out of it and told me that this was removed to make starting easier - suspect it is running too lean on the pilot circuit. Will be stripping the carb on the weekend and also checking if the other mods have been done -

been searching on this board for a few weeks and you guys have some good stuff on here.

have a yz426 motor with a 444 piston in it - will be fitting soon - and going to motard the bike

cheers for now
