Penton Hare Scrambler exhaust

[Daniel P. McEntee]

Hey Mike;
   How does his frame number compare to the frame number from the parts bike you brought back from Chicago? Is that one still the earliest '74 you have found? I have been watching this thread and wondering why it had a red air box and tank. My '73 was made in September I think. And there are some little differences between the '73 and '74 frames, correct?
   Type at you later,

Dan, That frame is a 311 date frame also and the engine you have is 1874, which is close to the 1964 engine number I have, as I recall. The only significant difference In 74 vs. 73 frames is the type of rear fender mount tabs and possibly a slightly different location for the exhaust pipe mount above the engine, and the rear exhaust mount.

I had one of the very earliest '73's that I bought in September '73. It was common back then to chop the exhaust and add an aftermarket aluminum Skyways silencer. It did drop some of the weight.

The following two pics were in early March '74 on a trip back to California. The Harescramble in the background was Carl's old ride which belonged to a my racing bud. I was 19 then. On this trip Carl warranted the frame and I had to scramble to strip the frame down for the exchange. The mud and grit were at the Old Hangtown site in Plymouth.





Showroom stock Sucks!!!!!

I never saw a black barreled Harescrambler like on the early Jackpiners. Even my 309 barn find had a raw aluminum barrel

Doug,

   Neat photos, thanks for posting them. When you mention Carl, would that be Carl Cranke?  

   I have engine 3 5400341 sitting here and the cylinder on it is as you described, raw.

  There is a magnetic sign on the side of the pickup, was that from a shop?
Love hearing about shops from "back in the day" if that is what it is.

This is how cylinder and cylinder head looked when I got them (after cleaning off the mud):



When looking at the cylinder from below:



When glass bead blasting the parts it was observed that the paint on the head was extremely tough to take off while the paint on the barrel came right off. Perhaps this indicates that the paint on the barrel was not original but applied by some owner. However, it looked as if it was applied by brush on both parts. I didn't know what to make of this, so I painted both parts black to replicate the original appearance.
Does anybody have an engine with a lower serial number or is mine particularly early?

Cheers

Andreas
