Hi all,
New Member here, as a brief introduction I used to occasionally campaign my 'not stock' '62 Sportster ('coffee racer' w/Cerianis, 4 shoe, Konis etc) at Fremont Ca. in the Early '70's (11.5/135 mph) Then I settled into life as a married man with no motorcycles.
And now, 50 years later this XLR fell in my lap.
I'm slowly assembling/mocking up 62XLR 2069 - a 'Super Basket Case' and finding in the details an interesting learning curve!
So... I have been searching for information which brought me here, because this is mostly a KR!
Perhaps someone will know this bike? As far as I know it came from the Bay Area. Orange rocker boxes, Ceriani gp forks modified to take the a 9HD front brake (missing), rear brake backing plate also has remnants of orange paint, lots of lightening holes...
This thing, which was a race bike, came as parts in many old cardboard boxes, some wrong, some correct and some still unknown. It has suffered a hard life, but I'm confident it can be returned to the land of the living! (I am a machinist) As it progresses I will keep you in the loop, but it will be a slow journey!
(Cases are '58R, casting date 7-60m timing cover has same date code)
This bit is interesting:
I have a set of 4ea. 59R pushrods (still in the original wrappers)
Compared to standard Sportster they look very similar but:
59R pushrods are .440" dia, Sportster is .500"
59R weigh 68.4 G, Sportster is 47.4G
Not exactly what I expected to find!
(It has been suggested these were smaller dia perhaps because of possible pushrod/rocker box interference with a high lift cam, but.. they are heavy! it has been fun speculating on the 'why did they introduce these in '59"?
Any thoughts?
Thank you
