2017 RGS.

Just installed air cleaner
new 14" KST bars
engine black out kit

started the bike up after all that and the idle shot up to 3k on start then slowed down to a steady 2 for a bit. Shit it down and back up again idled at 1500-1800 and the header got red hot. Upon shut down the bike made a weird noise like the rings sliding down the jug with no oil kinda noise. Opened the hose to the oil cooler on both side of the head and a little oil came out.

I wanted to get a video but was scared of running it again as it was very hot. This was all at idle and for only about 2 minutes of run time.

Question is.... why would it be running so hot? Why would the idle be so high and surge from 1500-1800? How much oil should be in the oil lines when the bike is off? The noise upon shut down was the scariest thing.

I will try to get a video tomorrow!
any suggestions as to where i should start?

Are you sure nothing was lose in the A/C and could have been suck into the throttle body? I would start with pulling the A/C cover and filter off and start inventorying everything.

you could be right. i remember putting the SE AC on and it wouldn’t seat right and i had to really crank the bolts to seat it. i may have cracked something in the throttle body.

would that cause the engine to run hot?

I'd start with dismantling the air cleaner and give your throttle body a VERY good once over. If that air cleaner wasn't seated properly, or, god forbid, you've cracked that PLASTIC throttle body, that lets in more air and the motor is reacting to it and the ecm is trying to get it under control. Especially in the throttle body, as in ALL things on a bike motor, if you're getting resistance then something isn't right. Back the screws/bolts out, make sure everything is kosher, and try again.

Check it for trouble codes first. Be ready to write them down as there might be a few. If there are codes, sort them out first. Changing bars often causes issues.

Then I would have a look at the air breather. The breather itself is not going to cause this, but a bad install job could. There is a harness that could be pinched. And there is the issue of the steel support bracket, some breathers keep it, some discard it. Getting that wrong could cause a high idle condition. And a couple of minutes at 2500 sitting still on a cold start could turn the pipes red. You really should get in the habit of having a fan ready to blow air on it. If you got the support bracket part messed up, its real easy to break those plastic manifolds.

I have no idea about the noises, but it's not dry rings. Might have been the stepper motor returning the throttle blade to the original park position. Or not.......

And I have no idea as to what a blackout kit is. In my day it was covers for the lamps.
No not really, but what did you black out? Just shields? Or cam covers and rocker boxes and such?

What he said ^^^ get a cheap box fan to blow on the bike when idling in the garage.

I'm going to take a stab at this and say that this is why you always read the instructions even if you wrench for a living. The metal bracket on the throttle body required removal and the intake was installed without it being removed. Quite possibly cracked the intake and the throttle body.

Bingo. I took it apart and saw the damn bracket still there. Few beers too many?

Inspect everything and if all is good, remove the bracket and reassemble. Let us know the outcome.
