Well, I don't have anything quite as exotic as a JP Norton or a Triumph Trident but my other ride is a 2007 Honda ST1300 (Pan European to the EU crowd). The ST is a 730 lb, liquid cooled V-4, 32 valve DOHC, EFI, fully faired, mon-shock shafty with linked ABS brakes, electrically adjustable headlights and a windscreen that is also powered up and down, a transporter beam and a full suite of photon torpedoes. The first time I uncorked it on the highway (to quote Clint Eastwood in Firefox when he opened up that Russian fighter he had just purloined), all I could say was...."Is this a machine!" I may have also said, "holy crap!!!" - or something along those lines. That thing could tow an XS650 much much faster than it could go under its own power - easily.
Anyhow, my ST has about 51,000 km on it which is nothing for one of those scooters, and has been trouble free until late in the autumn when I was unlucky in that mine has developed a small leak in the clutch slave cylinder (let's call it that f@cking thing ....or the CSC for short).
The CSC is a little round hydraulic gizmo-thing - smaller than a hockey puck (for Canadians), the size of an Oreo cookie (for Americans), a Tim-Tam (for Aussies & Kiwis) or a scone (for Brits). It costs about $75 CAD (about 8 dollars American or 157 quid U.K...post Brexit). It is held onto the rear engine case by three crummy little 6mm bolts and it has a double banjo bolt hydraulic fitting on it. The problem is that the space in which the CSC is located is extremely tight being in the middle of the bike, about 8" above the top of the centre stand pivot, about 50 mm in front of the swing arm and blocked by the gear shift linkage, the oil filter and whole sh!tload of wiring and drain hoses.
The Honda shop manual procedure for changing the CSC reads like this:
1) drain clutch hydraulic system fluid;
2) remove engine from frame;
3) remove three fixing bolts and hydraulic fitting;
4) remove CSC and replace with new unit;
5) installation is the reverse of the above;
6) refill and bleed the clutch hydraulic system.
This is all good except for steps 2) and 5), the combined labour cost of which is $1273 CAD.
Sorry Uncle Soichiro - but on this particular repair task - YOU SUCK!!!!!
