hurt motor????
Well I pulled the pan on the 14 and everything looks good under there no gold flakes at all, well anyways the knocking sound comes and goes, and the bike will start and run with no smoke at all but it won't idle by its self, ill have to keep it going. Also when I bring up the RPM it feels like its working and putting a load on the motor, and boost will build and hold if I just rev it up and hold it at about 5k RPM, what could this be guys?

Deformed pistons maybe from heat. Sounds like some tight wrist pins if it feels like it's in a bind. be careful reving it because it could break one off. Hard to really say without hearing it my self but for sure you hurt a rotating assy. With as many miles as you have on it just pull it down, check everything and see what the problem was.

There's probably a melted piston or 2 causing the tight motor. Could be the pins or bent rods too.
If it were bearings you would be hearing plenty of noise and you would have seen fools gold in the oil pan.
Check the spark plugs , you might or might not see a little aluminum from the pistons on them.
Try turning the motor over by hand and listen for where any noise comes from.
No matter what you do though it looks like the motor is gonna have to come apart.

Check cams for siezure, check valve springs for breakage, check for broken valve shims.
Not having the machine in front of me is only a guess.
If you have a turbo make sure the turbo bearing isnt siezing up, lack of oil to turbo will cause almost what you're speaking of...should be a screen for filtration to turbo bearing.
