Still awaiting jets... but decided to try drilling my existing ones a little fatter.
Gotta say, dropping the bowl on the ATV is a lot easier than on the moto.
Took my #40 pilot and opened it up to ~#45 (.45mm).
Took my ~#110 main and opened it up to ~#120 (1.2mm).
These changes made a pretty nice improvement. No more stalls if you touch the throttle while warming up... and it ran very well. No breaking up in the higher RPMs. Plug shows better... but still not quite tan enough color I'd like to see... but much better than before. Think I'll put in true 45/120 jets when I get my kit...and lift the needle one slot higher. That should get it very close to the sweet spot.
Strapped/bungied a lid to the rear to hold my battery so I could put the seat on this time. Rode it all over the yard... with a big smile on my face!
Next up... finalize jets/tune. Inspect and adjust brakes. Then bodywork time.
Cheers!
