RE: YS 160 Surging at idle

Be sure that your regulator is nice and clean. I know you said you cleaned it. The plunger should be a nice and shiny piece of brass...not dingy with fuel scum.

RE: YS63 FZ plunger

No its got the bubble impression of the opening...but that happens really quick in my experience. In fact in this one, it happend in 2 months and only about 20 tanks or so of fuel.

RE: YS63 FZ plunger

RE: 63 FZ top end rpm

The thickness or how big the snip is.
A new ring is $19.50, a bearings set is probably $20 ish, the other parts are probably much cheaper. Those are going to be the "high wear" parts.
