Thanks! I'll try some Honda brand MC oil first before I tear into the clutch. Bob

If you've put standard auto oil in the bike that's why your clutch is slipping. You need one without the friction modifiers. An oil change is a much easier job than tearing apart the clutch. -Kyle On Wed, Apr 20, 2011 at 9:33 AM, Bob Bunnell <bobbunn...@charter.net> wrote: Here's the complete story. Noticed a clutch slip in third gear a few days ago after the bike had been run and then sat for an hour or so. Went for an inspection yesterday[passed] then to the PO. Came out from PO, started bike, and engaged 1st gear. Let out clutch lever and the bike clutch appeared to slipping so badly that the bike could barely move, [the engine revving up with clutch lever released and in any gear]. The Honda service manual trouble shooting guide suggests causes as: 1. Hydraulic system sticking 2. Discs worn, 3. springs weak. There does not appear to be any adjustment for the hydraulic clutch throw distance. Using a Walmart brand 10w40 non synthetic in engine/gearbox right now..[the manual says to use 10w-40 SE or SF]. Not sure what the specs were on the oil I have in there, but will be changing the oil anyway, so will make sure I am using the right spec oil. Will drain oil today and take the clutch discs apart for measurement/inspection.also will measure the springs for proper length. More to follow..

What symptoms are telling you the clutch went out, as it may be a simpler solution than tearing down the pack.

Anyone have experience with 83-84 Nighthawk clutches? I'm guessing I'll need springs and plates. Any problem using full synthetic after the clutch rebuild [I have some on hand, so thought I'd use it up]?

Used a mix of parts from both bikes to make one. Runs well. Clutch seems to slip under hard acceleration in 3rd gear. I also noticed that the clutch lever has to only be barely squeezed to get the clutch disengaged [i.e. No free play at all]. Anyone have any experience with these clutches? Any adjustments? Suggestions? Thanks! PS: I have a bunch of spare parts if anyone needs them.
