To Be Brutaly Honest, If i knew a norton was booked in i took the day off work and sod the money.
I was working on all the japs plus Bm, Guzzi, Laverda, Ducati, Triumph plus the specials like Rickman, Dunstall Etc
what was really bad about Norton Commando's
All from memory
Early Isolastics
Valves + Guides
Pistons every 20,000 max (usually with rebore)
Gearbox bearings
Engine main bearings
points and Timing
Charging
Batteries that Vibrated to bits
Fuel tanks that split
Everything fell off
OK on the 1 in 20 that had just been rebuilt totaly the ride was good and the exhaust noise with peashooters was great but i would NEVER buy one.
What would i have if money was no object
Ducatic 750SS VERY few made and Phenomenal to ride
Next Ducati 900SS
Next Laverda 1,000 but not the Jota as that was just too brutal.
If i had to have just a bike for transport
Yamaha RD 350LC
Cheap to run, never needed that much and real fun
