<< Dave it sure sounds to me like maybe that scottoiler is oiling more
than the chain!!!! If I was you I'd try this: Disconnect the scott
oiler, or turn it off. Pull the rear caliper and check for oil on the
pads. Even if you don't see any I'd spray the shit of of the
pads/caliper with brake cleaner( make suer not to get the cleaner on
any painted parts) Then ride the bike for 100 or so miles and see if
it's better.. If it is better but not a lot then I'd change the rear
pads and either dump the scott oiler or figure out some way to keep
it from oiling your rear brake. If there is no difference then I'd
see the dealer. And of course make sure there's brake fluid in the
reservoir.

Exactly what I did yesterday, Erik. There was some oil on the disc, and I
noted that the pad on the side nearest the chain was worn less than the one
on the other side, suggesting that disc lubrication is most of my
problem-this situation was present after a fairly warm trip to Lagna Seca,
when the Scottoiler would have been flowing more freely than it was on my
trip to Daytona, in cooler temperatures. I did have the oiler turned down to
its lowest setting. I think that the proximity of the disc to the chain,
inherent in Triumph's single-sided swing arm design is partly to blame-the
disc is only 4" from the chain, about 1/2 the distance it would be on bikes
with a conventional swing arm, so that I think any lubricant applied to the
chain has much less distance to fling and splatter befor arriving at the
disc. Another part of my problem may be that the drip tube from the oiler
ended a lttle before the chain was fully engaged on the sprocket, possibly
allowing oil to splash towards the disc. I have extended the tube a little,
so that it now drips on the side plates of the chain further back, after the
chain is fully engaged.
After completely removeg all traces of oil with brake cleaner, and noting
that the Ferrodo pads were oil-free and quite abrasive, and cleaning all the
holes in the disc with pipe cleaners soaked in brake cleaner, my rear brake
still doesn't work. I am planning to check the pistons for free movement next
time I have the calliper off, install new pads, turn off the Scottoiler, and
see what happens. (Yes, there is bubble-free brake fluid in the system, and
the pedal feels quite hard)
Speaking of my warm trip back from Laguna Seca, I noted that I am getting
less heat under my thighs with the front of the fairing chin cut out, but
still more heat than I got with the belly pan off. I would recommend the
latter for those experiencing triple digit (F) temperatures. Dave Collins,
