MCO Stated Motorcycle, but when you submit the request on their website, in the notes on the form I also put in "Please make sure MCO states "Motorcycle" as the vehicle type." Just to be safe.

I will definitely look into the jet sizes you mentioned and buy 2-3 extras just because. I REALLY like this little bike. Uni filter coming, and I have a feeling a full exhaust will be in place shortly even tho I like the soundlevel of the stock exhaust as mine will be used for hunting too.

I adjusted mine before the first start too. The real difference was, mine never really changed noise level. I gather from your previous reply that your first run was with the oil that came in the bike, then you changed it over to Rotella. That is the reason why your valves likely got quieter. The oil that comes in these things is total garbage, and I don't entirely think it's motor oil lol.
The exhaust makes a huge difference, so it is worth doing, but I can understand your wanting to keep it quieter. The standard ebay exhaust is a bit louder obviously, but there is always the option to run a slightly more expensive FMF or Pro Circuit exhaust system, or swap out the muffler that comes with the Ebay system for something that has a removable silencer. The other option would be to at least gut the cat from the stock exhaust, and at least clean up the weld on the inlet side of the header pipe.
