If you are still out there and hav that rare Sector.....Just bought one myself! Not on road yet. Cuple things sorted, New front tyre, loosen chain/cleand and oiled. New headlight...messed up wiring, but took for inspection and MOT. Failed on headlight, loose steering head and crumbled front pads!
Steering quick fix, headlight will be sorted by MOT station, front brake....hmmm!
Fitted new pads, brake bleed fail! Caliper pistons removed/cleaned/refitted. I did a reverse bleed, then normal bleed...still no pressure! WAS WORKING FINE BEFORE! Looks like my master cylinder has no guts and may have slight blockage still...was very blocked.
Sourcing new unversal M/Cylinder online and getting new caliper pistons too..just incase.
When I travelled the 16 miles to the MOT, the bike struggled, the 1st 2. Stopped for fuel, wouldn't start for 1o minutes, then suddenly fires up! Dirt in carb methinks, ohwell just keep going and pray. Got to MOT ok, failed ofcourse. Ride back, I decided to ride normal and try it out a bit. Gotta say, it went really well! Carb clear. Pootling along flat road in 5th at 40mph...longish medium steep hill, down to 4th gear....pulled nicely and hitting near 50mph near top of hill!
Just waiting for my parts to fit, then its MOT time!
