OK. Its Easter ....and raining! So i might have a re-cap on the Lansdowne Kit , I still have a few guy's looking to improve their forks,and not sure which way to turn.
Risking covering old ground; Stock Norton dampers are little changed from 1953, and due to lack of development and funds these fifties damper's found there way into the Seventie's Commandos.
GOOD ENOUGH FOR A 500 COOKING SINGLE but 850 disc braked 125 mph Commando? Covenant mods give very little improvement...so working with Duncan Fitchett "We" found Rebound and Compression cartridge's a huge inprovement....After winning at Donnington his responce to my question was " Great, i dont have to think about the front end any more,just get on racing"
Duel rebound and compression was now controlling the forks using 10 grade fork fluid , Being fully adjustable ment they could be tuned quickly to suit the track, Belgium proved to be very bumpy but a quick "tweek" improved the action...allowing a great win .
The early Commando design based on Manx internals proved themselves to LAB ,Reggie and Mike [Forum members] Giving a instant improvement, My latest design have a few revisions. Now built in final rebound cushin [15mm] also a retension needle spring ..
The cartridge's have brass long life bearings and brass pistons.. Control via brass valves and a reliable taper needle Designed to last a life time.
Top nuts are aircraft spec alloy,bodie's cold draw hydraulic tube.. Designed to last and track tested ..All the best John Lansdowne Eng
