Kind of a shame: this tire is barely used.

Wow!  Those splines look like they're brand new! 

Those rear wheel bolts... Here I thought I had OCD.

On the exhaust, I polished mine by wet sanding with 2500 paper and soapy water.  The header pipes are all that needs to be done.  Anything you do to the muffler will just make it hazy.  I did mine in about 2 hours.

That's going to be a sweet ride.

I had what I think was dried bitumen and rubber over my muffler with little bits of gravel imbedded in it. Whatever it was for some reason the headers had escaped. Hence the need for extreme cleaning and buffing. I had to carefully use a brass brush to get the thick stuff off ( none of the chemicals I tried did much) then wet and dry. The haziness was taking out with buffing wheels on a 6" bench grinder and stainless buffing compound. For the hard to get to bits used an air grinder with cotton mops and compound.

Yeah, the splines showed no trace of wear, even though they were absolutely dry and slightly rusty.  The seal leakage concerns me a little, though.

My only current plan for the exhaust is to freshen up the heat shield: it’s pretty dull.

Thanks— pretty good for $625, right?

Nice find!  I know it was a work trade, but still nice....Looking forward to see pics of the tank ;) 

I am in the same place with the mirrors, I am going with the LED signals and bar mounted mirrors.  I do have two OEM mirrors one is missing the actual mirror.  I just don't like how they mount and how they get "bumped" off.  Lots of posts of how people tether them to the bike in case the fall off while riding.

Best of luck and keep the pics and posts coming.

You mean the tank interior, right?  I'll get some when I pump it out & replace the fuel pump.


Interesting...that tendency of the mirrors to fall off must be the reason they're so flippin' scarce & pricey.


Thank you-- I'll post as many pix as I have the presence of mind to snap.

Re: Reply #21, the pic of the final drive splines... OMG, those things look awesome for the mileage. Heck, they look awesome - Period. As far as the "rust" goes on those splines, the OE lubricant was Staburags NBU 30 PTM. Goes on white, pasty and sweet smelling (don't smell it btw), but in time it turns brown. It's my guess that is what you were seeing. Bike looks really good man. What's the tank look like? I hope for your case, the conditions of the splines serve as a good representation of the rest of the bike's innards.

The tank was the second biggest pleasant surprise on the bike: despite the fact it is half full of 16 year-old liquid varnish, it is almost completely clean.  I'll post some pix when I get to work on the fuel pump/filter.

16 year old fuel is probably moonshine-free, saving you from the destructive effects of corn likker.

I hadn't thought of that.


Whatever the cause, I was astonished when I looked in that fuel filler.  I expected hardened gnarl like I've found in old trucks I've worked on.

That muffler should polish out.  This is a forty buck unit I'm working on now for my '85RS.  Splines tell much.  Prolly the 64K miles is correct.  281 gears are good too.  gently takes you down the road.  Mostly early Ks are pretty used up.  you got what appears a very nice one.  almost as nice as mine.  Joke.

Just backlighting from what looks to be a gutted turn signal housing, I'm guessing.

That's disappointing. I'm interested in innovation wherever I can find it, especially if it's edible.

The inedible innovation in the choice of a drywall screw was both disappointing and amusing.

New development:

This is what I found today looking at the label under the seat:



Looking at the VIN label again produced more suspicion:



A little too tidily “damaged”.

The PO is a kind and decent man and a war veteran, so I can’t conclude he pulled the wool over my eyes.

Then I see more clearly what looks like ghosting through a respray on the tail section:



Still trying to sort out what this is telling me.

Did you look at the VIN stamped in the frame?  That sticker is really just for tire inflation information. 

If you don't have an iconic 22 top case the frame on the tail cowl is useless and I know I removed mine and plugged the mounting holes.

The VIN on the sticker wasn't what caught my eye: it's the way the build date was so neatly obscured.  Combine that with the '87 MY info under the seats and a couple Stellas, and I got suspicious, maybe excessively so.

Put the last 7 of the VIN here to get the build date:

On a bike as old as ours are, I wouldn't be surprised if the original tail cowl was replaced after it was damaged in a mishap.  That would explain the paint job and the filled in holes.  I think I noticed there was no paint code sticker.  That may have been removed when the replacement cowl was painted to avoid a conflicting paint code.

You say your bike is an '85, is that correct?  If that is true, the reason for the different tail cowl is probably that someone wanted to put on a later model seat that wouldn't work with the original cowl. 

The seat in the photo you posted with your intro shows a later model seat.
