Default Knocking 2100-2400 RPM

Hey Folks

I have a 2000 Electra Glide that I just purchased used. It has a 96" kit installed along with the upgraded cam chain and oil pump kit.

I have a knocking noise that only comes under load between 2100- 2400 rpm. It is hard to tell if it is top or bottom end but I think it is lower on the clutch side.

Any info or person experience would be helpful..

Thanks

service manual is going to be your friend here if you've got one....i'd pull the primary cover and check the compensator nut to see if it's loose or if there is a problem with the compensator itself...good starting point...

Good advice. Very common problem in the early models. If that is the problem, you can insure against future problems with a shim under the nut or trimming the nut by about .030" per the photo below. H-D sold shims in three thicknesses a few years back; .030", .060" and .090" IIRC; may still be available.

Generally, when a torque to angle spec is given, that angle from a specific pre-set torque value is the one that has been shown to provide the proper clamp load for the assy in question. The method for obtaining that angle value is somewhat beyond the scope of this forum, but a google search for "torque to angle", "torque to yield", etc. should prove interesting for those so inclined to investigate further.

AFAIK, pre '03 (tapered roller main roller bearing) have a torque spec of 150-165 ft/lbs and the '03 and later motors use the torque to value then to the specified angle. IIRC, that would be 150ft/lb plus another 1/4 turn. As previously posted, trimming the compensator nut ~0.030 or using a shim under the nut are commonly done to solve any stackup issues. You may want to check out HD bulletin M-1170 ...and I strongly recommend the H-D service manual.

Is the bike injected or carburated? Is the cam plate the S/E hybrid or a complete conversion to roller chains? Injected bikes with the M/M system are noisey when the stock air box is replaced with an open breather system.

I have a 2000 injected bike and had the same rpm range noise that you have. Converted to roller chains and put the stock air box back on to surpress the sound coming out the throttle body.
