MC,
You're right on the money. The bike wants to jump forward when I drop to first (from neutral or second).
Only way I can get to neutral now is to shut it off, go to neutral and restart. I will look into learning how to change the clutch. I don't know why it is, but with my very limited mechanical skills, I have a higher rate of successfully completing tasks than Paid mechanics (who end up on TV shows) ;-|

Thanks bro!
Wow that's sticky! But it does happen. It can happen just from sitting.  try this til you want to tackle the clutch. Put about 4 oz of SeaFoam in your oil. available at all auto stores. Ride it about 50 miles using the clutch a lot.  Then change out the oil to your favorite brand. That may free it up.

When the time comes you'll be disassembling the clutch. Remove the stack of plates. There are 8 fibre, 8 metal or something like that. Scrub them all with a stiff nylon brush in lots of solvent. Solvent tank if your local shop will let you. Its not hard. You'll need a gasket, a clutch nut tool and about 3 hours.

While you've got it out you could do HondaMans trick of drilling about 12 more holes in the clutch hub, there's many there already, that allows oil to get in between the plates.

Or you could replace them. But if its not slipping, that's not necessary.

i have always been told that the older versions of the 750 had "sloppy" clutch paks, hence the addition of the goldwing center riveted plate to quiet them down.  i put that plate in mine and have no issues now finding nuetral when running

Whoa!!! Before you tear the clutch apart, check the adjustment! Wasn't there a mention of the mirror interfering with the clutch lever? Also check the clutch lever pivot hole and bolt for wear.
Don't fix it if it ain't broke!

yes there were some things done like that. I've lost track, some worked better than others. I may be way off, but I think that plate, or some time of ring affair was introduced to help separate the plates when disengaged. Thus overcoming the stickiness.

Just checked, the K5 750 clutch plates actually carry GL1000 part numbers. 7 of one style, an 8th of a separate style.

A good clean stock clutch with the additional oil holes should work OK.

I think with the clutch adjusted to specs. ( easy to do )....you do have a shop manual OP , right ? , the N issue will go away, especially when you put a few miles on the bike... like do 100 miles in one session and when you get home you'll be feeling a lot better about your bike  ;)....

I jumped to the assumption that there was no interference with pulling the lever all the way, and that it was adjusted properly. Certainly these issues would contribute to your symptom and should be resloved first.. The lever must be free to pull all the way to the grip, and proper adjustment at the engine side adjuster, then the cable.

There are no interference in the clutch lever and I don't feel it slipping.

I'm familiar with seafoam as I freed up valves in a Shelby Cobra which was sitting for years. Just wasn't sure how much to use in a motorcycle. So 4Oz is good right? And I guess it'll be smoking some as well.

many thanks for your detail instructions. I will follow as you suggested.

Yeah the stuff works, eh? The can says 1.5 oz per quart. So 4+oz ought to do it. It also says that there is no need to change it out. But so many here cant stand the idea of leaving it in, I just say that so I won't get boo'ed off the board.  ;)

I have an old John Deere rider mower. Smokes every spring. Put some SF in it. Run it for 5 minutes, smoke goes away for the summer. I suspect a sticky scraper ring.

Whether it makes your bike smoke or not, I don't know. I wouldn't think so.

If it really did work on your clutch, it would be rinsing out caked/burned on oil residue and aluminum gray gook from the plates, so changing it may be a good idea, afterall.

Hi Nice Bike
But it does not sound good, it may be the cam tensioner has given up. In my opinion the noise is top end, any vibration coming from tensioner.
Suggest taking the sump plate off and check the oil pump screen for any rubber ,plastic material, this is a good indicator that something is not right.
Has the bike been tuned using synchro gauges, this has some bearing on engine noise.
