If you have the same carb as my Xciting, then you'll likely have a 98 main jet. Without changing the exhaust, I upjetted to a 105 and it runs much better at WOT, and tops out at 130 kmh.
There's a bit of a bog early mid range, I think it's due to the 35 pilot jet, so I'll try a 38 and hopefully quit messing with it.
Pretty simple surgery, actually, just drain the fuel bowl, loosen the intake and manifold clamps, pull the carb free and turn it over and expose the bowl, open it up, switch the jet and slip it back in.
No need to take off the throttle cable or enricher wires, just watch out for the temp sensor wire so it doesn't get unplugged while wou're wrestling the carb around.
