Unrideable... surely you jest..
.. sounds like the ramblings of an inexperienced point of view..
In 07 I rode my rigid rear 836 over 600 miles, in around 27hrs.. Which is not that hard to do, but it was my first ride of that year, and I had not ridden over a 250 mile day in over a decade.
So IMO it looks very rideable.. even has a sprung seat, wished mine had... Upright seating, mid pegs.. not so bad to ride..
I did not hear the clip, computer is too old.. but I will suggest that if anyone on here, has the inclination to build BOTH a 4-1 intake and exhaust, and get it working well, right off the bat, I will be impressed..... and if you win the World Chamionship with the build, that would be even better..
The intake/exhaust, had to work with the theme of the bike, those and the front timing cover pull off the early four look quite well, if you care to look at a few of the 20,s & 30's fours..
I really like that bike a lot...
