Thanks.
I'll order up a can of glyptal. I still learn something new every day.

Hey, nice to see this thread revived.
I missed your last question: Royal Enfield used an exhaust cam for the intake on high performance engines.
There was also an intake cam sprocket used for improved performance which had the woodruff keyway cut to provide advanced intake timing. This sprocket was marked with an "A" stamped on it.
The Interceptors were supposed to be available in three states of tune; the lowest used the original intake and exhaust cams, the middle one used two exhaust cams, and the highest state used the two exhaust cams as well as the advanced intake timing.
It' s possible that some of the 700cc Indian models had similar tunings.

Oh, and I rebuilt my Interceptor engine with no ill effects without re-coating the inside. I didn't know any better back then. I'd do it differently next time.

Btw, a repair in the oil tank due to a broken drive chain is apparently pretty common, I have two old crankcases with similar patches welded on.

I checked my intake cam sprocket. There is no "A" stamped.

I'm waffling about using the glyptal now. Some say its great some say it's just something to peel and plug oil ways.

I'm always waffling though. I seem to have motorcycle ADD. I can't seem to focus on one thing at a time. Around 2004 I got frustrated with commuting on an old bike and the constant fiddling to keep it running, and bought a Suzuki DL650 V-strom to commute The last two years it has been as troublesome as an old bike, but without the cool factor. It needs an engine overhaul. A 2000 Moto Guzzi V11 has come up for sale in my area, perhaps that would be a good commuter. Probably I need to follow Thoreau and simplify.

The same thing happened to me. I bought a brand new Aprilia Caponord so I'd have a modern bike for long trips and commuting.
Worked out great for the first three years, then one by one, the various problems they talked about on the Aprilia Forum started happening to mine.
A long list, mostly electrical problems related to flakey connectors, and a few weak components.
The only thing good is that the V-twin Rotax engine is reputed to be nearly indestructible, and it shows no sign of problems, but due to various electrical issues, cost/availability of some replacement parts, it's probably spent more time sitting unusable than any other bike I've owned, and that includes my Royal Enfield and a BSA. Compared to my airhead BMW's the record has been awful.

Although I have been absent. I have been busy.

I've cleaned and primed many parts.
Today I ran up to the machine shop and picked up some finished parts. This is better than Christmas.

Cylinders were bored for .040 oversized pistons. This was necessary for rust and pitting from formerly stuck rings.

The heads got new guides, valves. The left heads on both engines had damaged spark plug holes. The machinist took the best one and had a friend weld the hole shut, then recut the hole and put in an insert. It turned out pretty nice.

New pistons and rings, of course. The crank was just polished and the connecting rods had the threads repaired.

I need to buy new main bearings, rod bearings and a gasket set and I'll put it back together. Oh, I scrubbed, washed, boiled the case halves, but I'm going to paint on glyptal.

This may be all the work I do on it for a while. I have to get the engine together and well oiled, but I also have the engines apart in my V-strom and CT70.

Just putting pictures on now and thought it'd be a great idea to organize my pictures, that messed up the links.......boy am I an idiot.
