Can't find timing marks on 1980 R65

I can only see the OT mark on my flywheel. My son I and have looked very carefully and even used an endoscope to find the marks but no luck. Any suggestions? I thought of putting a degree wheel on the camshaft but does the cam rotate the same as the crank? Or perhaps I can remove the ignition soup c...

Re: Condensor insulation melted (twice )

OK today I have tried to measure the melting temperature the spade insulating plastic on my Bosch condenser . I had scrapped off and saved the melted material the second time it happened. To measure I used my Fluke Thermometer gun. I jerry rigged a double boiler using a tiny frying pan and a metal j...

Re: Condensor insulation melted (twice )

I have put back the old condenser which was on the bike when I bought it and so far have enjoyed some good rides back and forth to work. Of course I am not yet trusting the motor for a longer drive and even locally I have not driven again in bumper to bumper traffic on a hot day. I'd like to underst...

Re: Condensor insulation melted (twice )

First thanks for all the hard thinking on this subject. OK here are a few pictures. Today with the tank off I tested the new coils I bought from Moto. They both seem perfect, 1.3 ohms between 1 and 15 (the small terminals and about 6.1 between the spark plug wire hole and 1 or 15. The new plug wire ...

Re: Condensor insulation melted (twice )

This bike has the can (soup can) which contains the points and the advance mechanism. I like this system as you remove the whole can and can go to a workbench to change the points. The condenser is mounted on the outside of the soup can. It has a square shaped plastic isolation piece which plugs int...

Re: Condensor insulation melted (twice )

Hi St. First new set of points and condenser were a cheap set sold as a pair. When the first plastic melted I said ah ha, cheap set and I ordered a $25 points and $25 condenser from MAX. (however I'm not positive I put the expensive condenser in. It may have been another less expensive one.). I did ...

Condensor insulation melted (twice )

My 1980 R65 has twice melted the plastic insulating block causing the spade connector to short out to the metal points case (soup can style on my bike.) Is the motor getting too hot or is the plastic used for the insulating block an incorrect material? Is some electrical problem causing the condense...

Re: R65 gas cap stuck

Here is the end of the story with my mucked up R65 tank. I actually got it to look pretty clean inside after soaking the old sludge with a few gallons of denatured alcohol for a month and putting in old nuts and bolts and shaking it a few times every day. I had to use a magnet fastened to a length o...

Re: R65 gas cap stuck

Thanks for the plug suggestions Kurt and Ray. McMaster-Carr is one of my favorite businesses. My new cap did arrive yesterday. I'm going to try to stretch a thin plastic over the threads and see if I can screw it in and seal the tank without gooping up the new cap. And St. thanks for the reminder to...
