Ok here is the background on the bike and what was done.
1975 RE5 8,100 miles on it.
Under 200 miles prior.
Oil change, Anti-freeze change, points checked, retimed, carb rebuilt, and port valve adjusted, One way oil metering valve checked. Oil metering checked per manual with graduated cylinder with oil in it.
Riding home from work about 6 miles on a straight away traveling 40-45 MPH. A bang….locked rear wheel….and enough white smoke I couldn’t see the car that was following me. I squeezed the clutch hopping the car I could no longer see would not run me over. Rear wheel rolled and coasted to where I could pull over.
The white smoke was anti-freeze dumping into the exhaust. After getting the bike home I found the motor was seized.
There was no shutter, chatter, it sounded and felt normal until the bang
I went to Rotary Recycle for a used proper. During the break down of the bike there was a crack through the block. OK how can you through a rotor? Taking off the carb…..there is a crack right through the intake manifold. Tip the carb and anti-freeze comes out. The forward engine mount bolt had to be tapped out with a hammer.
Now the cracked proper was opened …
The block broke across three places. At the engine mount between the intake and exhaust, just above the intake and one more the first one visible just above that.
The tips on the rotor are all in different conditions. One is welded itself, one broke, and one is more or less normal.
Unable to tell what happened first. My first thought before opening it up was that the gasket allowed water in and hydro locked and pushed the rotor.
No anti-freeze found in the proper.
The rotor was donated to Rotary Recycle for display.
The proper was installed. New Rotary Recycle check valve installed. Intake manifold and gasket set along with new hoses. Same carb (anti-freeze drained out) no adjustments made. Touched the starter and fired right up. Tune up still good no hesitation.
I want to send a heartfelt thank you to the boys (and Barb) at Rotary Recycle for saving my ride. I also want to mention the unquestioned superiority in the new gaskets Jess had had manufactured. These are truly compressible gaskets, better than stock and not a cheap knock off.
