Had a problem with my px200disc, (2001 model std 24 mil carb, simonini exhaust)
was running rich, on both 116 & 118 main jet changed cleaned filter, plugs(NGK 6 to [H] and adjusted the mixture screw. Got running fine by plug colour, however when in top gear at 3/4 moving up to full throttle, feels as if sticking / not firing right, more so when uphill or into wind. When I adjust the mixture to more rich this goes away but then is running too rich and fouling plugs on the 116 jet???
Any ideas on what to try next, or what this could be
Thanks in advance, Malcolm
