Don't be silly, I've got some TwoWheels motorcycle magazines which have dyno charts of road bikes that they tested from the 1980s.acotrel said:About dyno testing bikes which use methanol. In Australia we've only had bike dynos for probably the last 15 years,
By the Sydney-based ? accounts they published, those folks were very experienced with their dyno even then.
Cook Nielsen in Cycle Magazine (USA) in the 1970s somewhere published a very good series of accounts of dyno testing and developing an XT500,
or TT500 was it?, which they were using in enduro racing ? It details removing the airbox and fitting a larger carbie and different exhausts,
which they ran through a whole series of dyno tests to get maximum torque and a healthy power output. There are a lot of hop-up tricks for the
XT500, and they ran through practically the whole lot of them, one by one. Very strong engine by the time they finished, would have to find the
mag to see what they ended up with...
P.S. I seem to remember they tested a whole series of different carbies in this thing, to see which worked best.
Each one required a little fiddling to get the best from it.
