Put a UNI filter and A DG pipe on it last night. The carb wasnt jetted stock, it had stock pilot and needle position, but a 110 main. It was cutting out a little if you opened throttle quickly once warm, so I'm nearly certain it is rich up top and a little lean down low but the choke was never needed even to start if 30 degrees outside. I upped to a 40 pilot, shimmed needle, and dropped main to 105, hows that sound?? anyone familiar with that setup on a 200e?

Tore into her again yesterday for some fine tuning, She now runs well, and there is a noticeable difference in power. The DG Exhaust sounds nice and is lower pitched than I expected considering the small bore. It's also not loud enough to piss off the neighbors (as long as they are inside) and it pulls better now so on my drift track I can now stay in 3rd gear instead of dropping to second to climb the uphill on the back straight.

Current setup:
DG Pipe
Uni Filter
Stock Airbox configuration
Pilot : 40
Needle : Middle notch + 1 shim
Main : 105
A/F Screw 2.5 turns out

I'd say some may be ok with a 100 main
