My newly acquired MC21 seems to use an awful lot of 2 stroke oil (full tank in around 400km's or so). It also smokes quite a bit. I checked the pump when I first got it and aligned the marks with a fully open throttle - it was actually set a little 'rich' so I thought that adjusting it would cut the smoke a bit but it hasn't seemed to do so particularly noticeably.

Is that kind of consumption normal? It seems to use a lot more and smoke a lot more than my TZR 3XV's. The tank could be smaller of course and the 3XV oil feed is fairly sophisticated - adjusting the oil feed according to revs and engine load so it's pretty frugal on oil.

Do any of you fella's run the pump backed off a bit? And if so can you offer any pointers? Ie: How much? I'm tempted to back it down a bit, but, obviously, don't want to damage my motor.

Any guidance gratefully received.

Cheers
