How's your eye Yogi?
Yogi said:Just zoomed in on the header - see what you mean. Not too sure what tail end of exhaust is going to look like either, but I like the colour scheme frame matching bodywork - keeps it simple.
Eyes are so-so - got a 'shadow' in the other eye that pisses me off and the calibration between the two and the brain makes me lack a bit of confidence in what I am seeing and what I am not seeing. Minor problems compared to what other mates are going through at present...
How's your bike coming along - not seen any photos for a bit. Has it had to take a back seat for time being?

Sorry to hear about Noyes re MotoGP, though most of what he writes is in Spanish so unfortunately I won't miss it.

Sorry, but not bleedin' likely.![]()
sfcpiet said:Don't think piston speed would have been the limiting factor. Pistons were of good quality and cooling worked well. Speedway pistons have to put up with about the same speed, but for a longer period, and they seem to have reached an astonishing reliabilty level. Taking the little twin (580cc) to 13000 before snicking up a gear, it only peaks for a couple of seconds at the most. It out-ran most of the big guns competing in the german BoT series, the competitors wouldn't believe the displacement. Sadly, Georg wasn't up to the task of running at the front of the field. St?ggi, from here on the forum, took it to 3rd or 4th place at Hockenheim (iIrc) on his very first outing on the bike, trouncing the big Beemers, Guzzis and Ducs that were so poular at the time. Engine made something around 80hp and chassis was very light. Ultimately, the cases cracked up under the power.
Love it... What bore and stroke was the engine, Piet?
