Dave were at squires this weekend,[ fizzy run ].. that r/h crank seal "  my H2  had a fooked r/h.  it smoked like hell on the  top pipe, . even when hot, [ other 2 clean],  anyway  I fouled the plug on that pot,  . running slow behind other bikes on run, ,it never  blew into oil, it just sucked into crankcase, ,  Up the pilot dave, andclose the airscrew a bit, ,  it should smooth it out,

 

Right, I don't really want to do another strip, it's summer and we all have things to do ! I'll buy larger pilot and see what happens, thanks for badgering me.
