Title: cr250 83 seems to be flooding at mid RPM. wont rev up
Post by: oldyzman on February 26, 2011, 11:43:05 pm

So i got through the issue of the wrong piston being fitted to this bike, have now rebored using  a new wossner piston. thing is it will not rev up to the high range. seems to be flooding i have tried MJ down to 280, doesnt seem to make a difference. I have changed th jet needle everywhere i see the correct jetneedle for a VM36 is a 159 ... this size seems too short for this VM. and it had a 247 ... in it. Could this be the issue. i thought that timing was the prob, but i have noticed that there is no adj for this as one mount hole is slotted and the other is round on the mount plate. These CR's are funny cattle..
