The engine is in super condition.
I changed the engine sprocket from 19T, using the bike to pull a Watsonian Monaco side car,
and changed it to solo with a 21T.
The engine was too low geared for high way cruising and uncomfortable at 50 mph.
It was like I could only use 1st and 4th gear. 2nd and 3rd was newer used.
This year I changed the engine sprocket from 21 to 23T
Nice. Much more compatible at 50 mph.
To gain more speed, I change down to 3rd at 50 mph. and keep it in 3rd until 70 mph +
The 357 cam like revs. and have a kind of flat spot between 45-60 mph.
I can keep it in 3rd, but as posted before, the gearbox have a tendency to jump out of 3rd if pushed hard.
Try to do 80-90mph in 3rd is not possible, for the time being.
The gearbox will be send to SRM this winter for a rebuild.
But the bike should be able to reach the Ton. Why is that important ?
If it can´t do the Ton, it ain't a Ton up Bike !
