Dale is probably right on suspecting this. This was a more common failure than folks seem to realize. I was at Matt Assenmacher's just a week or two ago and there was a customer bringing such a bike in for repair. Matt pulled the joint apart for us and showed us the lack of penetration from the brazing process. He says he sees them like this from time to time. He suspects that at the factory someone was working the job that was responsible that was not a regular on that job.
I believe the bike was from the early to mid '70s, but do not remember for sure.
Several CRT listers , including myself, Mark Agree, Tim Potter, Gene Diggs, and one or two others, not so well known to me met up at the Rochester Hills track today and took the track riding 101 class and then took to the track.veterans of high bank tracks will no doubt snicker at the level of intimidation I felt to be taking to such an enterprise at 66 years of age, but it was great fun. Gene , of course is a grizzled journeyman track rider who, even though he's 74, has several thousand miles of track riding under his belt this year! Vintage track bikes were in abundance and some were sort of jaw dropping. The track management showed us a couple of tricks about assessing proper chain tension and such and a great time was had by all.some parts were swapped in the parking lot and a good meal enjoyed afterward.all seemed a bit tired, but happy and we hope to do it again in a couple of weeks. As always Tim and Mark impressed with how strong they were on the bikes, but I gotta tell you there was an 11 year old girl there that was fantastic, and she is a first year rider! Hope to see her in some really serious competition in the next few years.really fast!
