Hi everyone,
Here are some pictures of my KRM TT special. Frame is one of the 5 Branch-framed specials that are mentioned in Girdler's book.
I know of 2 others in California, and saw one with an XLR engine in it on eBay years ago - I believe that bike was from Florida.
The frame uses big twin springer legs to bring the shocks to an upright position. Front is a later addition of Ceriani 35mm MX forks.
I understand that this bike was built in 1960.
Some other interesting parts to note are the road race rear drum with fins, with a reinforced backing plate.
The generator is an all aluminium finned unit that I believe was made by the previous owner - a machinist in LA.
Cams are all KR grinds, with the number 4 cam a factory experimental grind (this cam sadly no longer in my possession).
Ignore the front wheel - that's just to push it around for now.
There are more interesting things about the engine that I will post when I get around to taking pictures.
