You should probably stop about where you are. 😛

The most over-looked and under-appreciated maintenance items are replacing the front fork oil and brake fluid. And those are 1/10th the trouble of what you're already into.

Photos please when it's back on the road, my friend !

Ah, not to worry, the fork seals, fork oil, steering bearings and all brake lines, new M/C and fluid flush were all done in the Fall of 2016.
At this time, only the crank, rods and timing chain/tensioner have been overlooked.

I am feeling pretty confident in reliability for 2017.

I got a lot done in the last few days.

I cleaned and re-packed the swing-arm bearings, cleaned and lubed the clutch spline, replaced the neutral switch and oil sender, replaced the speedo cable boot, and got the back end put back together:

On examining the heads that I removed, it was clear that not only was this '84 among those with soft valve seats, the exhaust were badly hammered and the exhaust valves badly "tuliped".
Rather than fork out the $1000 or so to ship them to one of the trusted seat replacement shops, I scrounged up a pair of low-ish mileage 1994 R100RT heads to use. They have the newer valve seats and also have larger valves. The R80 heads were 38mm/40mm, and the R100 heads are 40mm/42mm, but still have the same 32mm carb spigots and 38mm exhaust flanges. All they needed was two exhaust guides replaced, and the seats cut and valves faced.

So I did that.
Installed New Guides:

continued . . .

Then . . .

Cut the valve seats:

Lapped in the valves, cleaned and re-assembked the heads, then assembled the top end with all new o-rings, gaskets, pushrod tube seals, etc.

Oh, and those are new exhaust nuts, too (with anti-seize on the threads).

And new carb rubbers:

Tomorrow I'll get the left carb installed and all cables re-adjusted, etc., re-torque the heads, and hopefully fire it up.

I also recently acquired a set of original correct crash bars and a genuine San Jose fork brace for this bike:

As soon as I finish with the mechanical stuff, and verify that all is well, I'll bead blast and re-paint the bars and fork brace and get them installed.

My roads are solid ice and frozen snow right now, so I won't even get the carbs balanced and fine tuning done for a while, since I can't ride anywhere to warm it up sufficiently.

Sounds like somebodys got money to burn

On the contrary, I am trying to bring the maintenance up to date on a neglected bike I purchased used in 2016.
All of the repairs/maintenance are simply due and necessary.
Replacing heads was far cheaper than having new seats installed in the old ones, which could not be re-used without complete overhauls. Everything else has been bearings and seals, gaskets, o-rings, etc., which need attention every 20 or 30 years anyway. I do all of the work myself, so as to save labor costs, and because I enjoy it.
The crash bars were a good deal, purchased used, as was the fork brace, which I picked up for far less than current market value, or I wouldn't have purchased it.
I am cheap, retired and live on a fixed income, so have no "money to burn".
That's why I am an AirHead.

...or forgot to take his Ritalin. 😆

Makes me tired just thinking about all that.

I wish i was that mechanically inclinded......I am just a oil changer and and break fluid flusher.....and valve adjuster....good for you i was only kidding like i said i wish i had the skills.....ridefast99

I finished up the winter maintenance today.
Got the fork brace and crash bars installed:

And the new valve covers I got for Chrtstmas:

I strapped my old Vetter tank bag on it:

Now I am ready for spring . . .

I have run it up to operating temp and cooled down a couple of times, then reset the valves. Now I just need some snowless roads to put some miles on it, then adjust valves once more, sync carbs and hit the road!

Great pix! Where did you find the crash bars?

Thanks,

They are BMW accessory crash bars, that I found on eBay.
