RS 50 smoking a bit

Post by Bikerz on Sat Sep 12, 2009 1:50 am

I have a very very low millage RS50 (ok Charlie does).

It smokes far too much, how do I adjust the oil mix? Ive read manual and only adjustment seems to be make sure the cable pulls at teh correct amount and line up the marks on the poil pump, is there an adjustment screw?

Cheers

iirc the oil pump takes shims, so you can adjust the stroke on the pump- how much it pumps.

But if she is only doing it for short journeys, it will happen normaly (carbon building up in the exhaust)

If you lean out the oil mix you MUST increase fuel mix.. or it will run too lean and seize.. lesson learnt for me Razz

And check gearbx oil, could be seals gone..

Colour!
Is it white smoke? - Water getting into the barrel.
Black? - Running too rich.
Blue? - Running too much 2t oil.

No smoke at all and getting hot riding? - Too lean.

I see the 2 farks one when thrttle fully open and one when fully closed, its slightly off, how do I adjust it? Do you alter length of cable or alter where it fits on spindle?

I recon it might just need a good speedy run and a new Spark plug really. Thats if she only rides the speed limits and doesnt get the revs high.
