Borrowing a GS-911

[hovis]

Is that checked visually or checked by swapping out for known good ones ?

As unless there badly damaged you don't always see the degradation that leads blast) to the breakdown of the insulation under load

by swapping.

Ok, I'll bite with the compressed air noise - are the throttle body O-rings, connectors and vacuum uptakes all intact ?

A.

Ian spent whole morning fixing the bike. Lots of things fixed. Throttle bodies adjusted. Valves adjusted. problem? still there...
there are little cracks on the O-rings you mentioned. Not sure if they're just on the surface of all the way through. Bike seems to be running good now but on the idle. Tried to test ride it...dies almost immediately after moving.

Hopefully Ian can shed some light on it later on.

get some talc powder and with the bike running lightly dust the area about the TB and see if the talc gets sucked into the TB if it does the seals are goosed

Bike was missing rubbers off the two vacuum guage attachment points and bleed screws around 3 turns out.
A bit concerned that those two issues plus throttle body rubbers that deffo. look perished may have had it running on such a lean mixture that the run down from Aberdeen could have resulted in so lean a mixture that valves have suffered. Plugs that had been changed since then were burnt white. Hmm.
Need to check with a compression tester and rubbers off my R perhaps.
Then there's the thought of what numbers the TPS is sending.
Three things to try as well as wondering about a fuel pump not delivering enough...
