Exhause valve solenoid leaking

Oil

Sounds like a bellows with a hole on it.

Having the hose weep black oily good is normal. It can make a heck of a mess on the garage floor or on the trailer.

Throttle response could be just a matter of clutching.

At 1200 miles it's probably time to replace the fuel filter but I don't know if that is going to affect your throttle response.

You should be seeing low rpm blowby out of the VES solenoid on the Indy, too. I'd suspect the hose is plugged if it's perfectly clean at the business end of the hose. Many of us reroute that hose with longer std fuel line to the chaincase drain area in the belly, among other options, depending on how you store the sled (where it won't end up in a perpetual ice ball all winter). Goal is to get the spewy away from the clutches. It's a dumb design on poos part, regardless.

Can't speak directly to the RMK's throttle response, could be anything from the fuel filter to a sacked clutch spring, etc. The RMK should actually be more responsive, with lower gearing and a deeper lug track. The stock indy 6, non-SP track is like a slipper on snow. 1.25 ripsaw II really wakes up the indy 6.

Eric, do yourself a favor if you can - put a new belt on it, unless you know the one you have has less than 200 miles and it has no cords pulled. Set belt deflection so the track will just turn on its own at idle, but never squeal. Have the sled warmed up, and the track not stone cold. Best way to set deflection. If the springs are sacked in the primary or secondary, or the bushings are worn, you can get stiction there, too. May be worth a going over. Good luck.
