I’ve just fitted a Malossi and SIP pipe on a 200 with std carb upjetted to 130.
All went well - started first time(!) and runs as expected, but when I reach 25/30mph it just stalls. No over revving, no strange noises, just acts like it’s run out of fuel…
The carb has been cleaned, no leaks anywhere…fuel in the tank, new fuel pipe…
Which jet(s) being used at this speed (at low revs as it’s running in)?
Also fitted a 23 cosa clutch - it’s absolutely amazing! With a teflon cable it’s like a knife through butter…wish I’d bought one years ago.
