been pulling the cover and cleaning the PV after almost every ride (we use a little mineral spirits or WD-40 and a soft bristle brush and just scrub the whole thing very thoroughly). I'm not sure why this helps, but my theory is that the carbon deposits tend to gum up the PV bearing, thus slowing or retarding the action of the PV.
Also, how's your jetting? Our bike was four sizes too rich in the pilot, rich in the needle and lean in the main compared to the jetting we currently run
(#42 pilot, LTR #1 needle; clip in the middle position (very close to an NOZF) and a #180 main - but we're riding pretty much at sea level). After we got the jetting worked out, the bike pulled stronger everywhere.

That's interesting about PV cover. (since I don't know what exactly that PV does any way!) I'm on EC250 that has seemed to have lost just a bit of off idle response I am going to try cleaning the PV. Is there a gasket there & if so should I have a new one on hand before I take off the PV?
Thanks
