Pilot: 42
Main: 108 (currently) also tried 115
Needle: 4th slot from the top. I also ran factory needle that has only one slot.
1000 ft elevation
Purchased bike brand new, only has about 1 hour on it which was with the full factory setup. Ever since I touched it things have been bad.
Unfortunately I can't reinstall the exhaust baffle or the air cleaner snorkel as I threw them away. I got tired of a garage full of old factory parts so tossed them before testing the bike (I know, dumb). I first started with the just changing the pilot and main jet not the needle. It never ran so I then purchased new needle, pilot, main, and adjustabe fuel screw. I read that removing the snorkel and exhaust baffle you must rejet and ajust the needle so I thought this woud fix it but no such luck. When you pass the 1/4 throttle mark the bike flat out chokes. If you are standing it will throw you over the bars. It doesn't die but spits and coughs. You can open the throttle wide open and it just keeps coughing and never cleans out. The bike does not like to run with full choke at all, 1/2 choke has the same behavior.
From what I understand the first 1/4 throttle is pilot screw, the 1/4-full is the main jet. I soaked the carb, sprayed with carb cleaner, blasted with 100 psi air.
Thanks for your help guys. If I can't figure it out I can always take it to a dealer just hoping I could save the time and some dollars.
