1983 R80ST Rebuild For Charity Project Journal

1983 R80ST Replace Connecting Rod Crankshaft Bearings, Measure Crankshaft Journal

Since this bike sat for more than 25 years and I found water in the oil pan, I replaced the connecting rod bearings. The bearings were in good condition and the crankshaft journals were not rusted and were well within specifications, so that was a relief. I replaced the bearing shells anyway rather than reuse the original ones that had 64,000+ miles on them.

You can read about how I do this work and see a short summary video here.

1983 R80ST Install Alternator, Diode Board & Electronic Ignition Sensor, aka, Beancan

I replaced these components with new ones supplied my Euro MotoElectrics at no cost to me in support of my goal to auction this bike and donate all the proceeds to the Motorcycle Relief Project. EME has been very kind and generous to me on this project.
I installed their new Type 1 charging system kit, the <a href="https://www.euromotoelectrics.com/product-p/edl1-107.htm" target="_blank" rel="noopener">EDL-1 107</a>, which has all the parts to replace the stock 240 watt charging system including a new front crankshaft seal.

I also installed their <a href="https://www.euromotoelectrics.com/product-p/beancanreman.htm" target="_blank" rel="noopener">remanufactured electronic ignition sensor, aka, the "Bean Can"</a>, and a new ignition system sub-harness.

You can read about how I did the work and see a YouTube video.

1983 R80ST Cylinder Measurement & Honing

This bike has the Nikasil plated aluminum cylinders. Nikasil is a nickel silicon carbide material that is extremely hard and wears very little and can be platted onto aluminum. That said, I want to measure the cylinders to determine if they are in good condition since the bike sat for about 25 years and had 64,000 miles on it.

<a title="Insert Bore Gauge Into Cylinder & Align With Top Measurement Circle" href="https://www.flickr.com/photos/brook-reams/52096762354/in/album-72177720296259835/" target="_blank" rel="noopener" data-flickr-embed="true" data-header="true"><img src="https://live.staticflickr.com/65535/52096762354_4f146dc7ce_c.jpg" alt="Insert Bore Gauge Into Cylinder & Align With Top Measurement Circle" width="800" height="450" /></a>
Insert Bore Gauge Into Cylinder & Align With Top Measurement Circle

I previously measured the cylinders on my 1973 R75/5 and you can see that procedure here.

</ul>
On this bike, I measure the bore, ovality and taper using a bore gauge to see if these cylinders are still serviceable. I found Both cylinders are in good condition.

After measuring the cylinders I remove the glaze on the cylinder walls using a ball hone. I use the Brush Research Flex-Hone® with 240 grit aluminum-oxide balls that they recommend for Nikasil cylinders. I use a 3-1/2 inch hone and my portable electric drill that has a low speed range of 600 RPM which is within the recommended 500-800 RPM Brush Research recommends.

1983 R80ST Remove & Install Drive Shaft

I had the swing arm powder coated, so I removed the drive shaft before taking it to the powder coater.

The 1983 R80ST swing arm is designed for a monoshock rear suspension, but the driveshaft is the same as the one used in the dual shock 1983 R100RS. I previously removed and installed the driveshaft in a 1983 R100RS and documented the work.

1983 R80ST Replace Swing Arm Bearings

I removed the swing arm bearings before I had the swing arm powder coated. The swing arm bearings are the same sealed bearings used on the 1983 R100RS that I previously rebuilt, so the procedure for replacing them on the R80ST is the same. In this document I link to the previous documentation for the 1983 R100RS as appropriate.

Here is a short video summarizing the work.

Earlier versions of the airhead swing arm used traditional bearings with a separate inner and outer race. I show how to replace that style swing arm bearing here.

1983 R80ST Replace Push Rod Tubes

I had the cylinders vapor blasted. In preparation, I removed the push rod tubes. After they were vapor blasted I install new stainless steel pushrod tubes I got from <a href="http://www.euromotoelectrics.com" target="_blank" rel="noopener">Euro MotoElectrics</a>, who graciously has agreed to provide the parts for this charity rebuild project for free. I will auction this bike and proceeds will go to the <a href="http://www.motorelief.org" target="_blank" rel="noopener">Motorcycle Relief Project.</a>

I have done this work before on my 1983 R100RS rebuild and will reference material from the documentation of that build as appropriate.

Excellent, as always, Brook.

Do you have any idea when you might complete the restoration?

SPP

Pete,

Indeed, I know exactly when I'll complete this restoration: The second I'm done. :) I hope to be done in 2023, which is the 40th anniversary of the introduction of the R80ST model.

Best.
Brook.
 
1983 R80ST Replace And Set Wheel Bearing Pre-Load

Before I install new stainless steel spokes and chrome plated brass spoke nipples, I replace the front wheel bearings. The rear wheel does not have wheel bearings. Instead it is mounted directly to the rear drive. Since the rear wheel does not have an axle, there is no need for wheel bearings.

Here is a link to the documentation on how I do this work and a short YouTube video that summarizes the procedure.

1983 R80ST Refinish, Lace And True Wheels

The R80ST has spoked wheels front and rear. In order to refinish the wheels using vapor blasting, I remove the spokes. This let me assess the condition of the spokes and spoke nipples so I can decide if I can keep most of them, or they need to be replaced.

On the rear wheel only 17 out of 40 spokes weren't bent or rusted and only 8 spoke nipples were not damaged. On the front wheel every spoke was bent. So I replace all the spokes with stainless steel spokes and install new plated brass nipples.

This documents how I do this work.

1983 R80ST Install Engine In The Frame

At last, I get to start putting this motorcycle back together. Every time I install an engine in the frame it's a milestone. Instead of taking things apart, I am starting down the road to getting it all back together again :).

Here is a link to the documentation and the video I shot.

1983 R80ST Install Engine Top End

The 1983 R80ST top end is the same as the 1983 R100RS with the exception of a smaller cylinder bore, piston and rings. I already thoroughly documented installing the engine top end for the 1983 R100RS, so I reuses a lot of that material as appropriate in the documentation and the summary video.

Here is the document and video links.

The Engine Before I Removed The Top End

The cylinders and heads were vapor blasted and I hand cleaned the engine block. I repainted the inner timing cover and top engine cover and had the frame powder coated.

Here is the engine with the top end installed. I put shop rags in the exhaust and intake ports of the heads to prevent anything from getting inside. I also put red tape on the temporary spark plugs and on the dip stick to alert me that I need to install new plugs and oil before I start the engine.

The 1983 R80ST top end is the same as the 1983 R100RS with the exception of a smaller cylinder bore, piston and rings. I already thoroughly documented installing the engine top end for the 1983 R100RS, so I reuses a lot of that material as appropriate in the documentation and the summary video.

Here is the document and video links.

Here is what I started with and the final result.

The Engine Before I Removed The Top End

The cylinders and heads were vapor blasted and I hand cleaned the engine block. I repainted the inner timing cover and top engine cover and had the frame powder coated.

Here is the engine with the top end installed. I put shop rags in the exhaust and intake ports of the heads to prevent anything from getting inside. I also put red tape on the temporary spark plugs and on the dip stick to alert me that I need to install new plugs and oil before I start the engine.

Sir, do you take projects/complete over hauls for customers? Do you ever sell the bikes you've restored or are they all for clients?

thanks, and great work on restoring the old gems

Brownie0486,

I'm an amature hobbyist. I don't do projects for customers. I've kept all the bikes I rebuilt except for this one which I will auction donating all the proceeds to the Motorcycle Relief Project. When I finish this one, I'll have to see what I do on the next project: try another charity build, or restore and sell. I haven't made that decision yet.

And thank you for your kind words.
 
1983 R80ST Rebuild, Refinish Carburetors

This bike came without any carburetors. I found a set of used 32 mm BING carburetors (64/32/323-324) after searching through a box of used carburetor's in one of Clem Cykowski's storage rooms. These are not the models used on the 1983 R80ST, but they will work. The date stamps on them indicate the 323 was manufactured in 11/1982 and the 324 was manufactured in 10/1982. I have to replace a lot of missing parts on the carburetors.

I repainted the emblems as the white paint was missing on one carburetor and pretty dull on the other.
