Worried about your trunnions? Relief is to hand!
This is an bit of an infomercial for my mate Dave and his company Canley Classics. I know Dave well, I get most of my Triumph stuff from him. I sometimes work on the Canley Classics stand at shows, I own a Canley Classics T shirt and I have spent many hours driving Triumphs with him. Other Triumph parts suppliers are available, your mileage may vary and this may contain nuts. If you don't like what I say, ignore it :-) - It's a well know fact that the small chassis Triumphs have some design frailties. One of the more spectacular failures you can suffer stems from the front trunnions. When you get a failure here you can loose a front wheel - this isn't a good thing. Often incorrectly known as "trunnion failure" what actually happens is that the vertical link that sits in the trunnion snaps - it does this for a number of reasons, lack of maintenance, fatigue, corrosion, previous trauma, bad luck. Most often it's the nearside that goes, it's the side that

Must be worth a good few HP over a pheonix castrator manifold.
I was looking at some re-CON ones at Malvern telling James how crap they were...Beadblast reconditioning.
Any ideas where you can get a quality item made and what it would cost??
Mind you, I can forgiv epeople for some of the PI screw ups, that whole air blead thing was news to me - ie you need the butterflies to shut tight (the crap helping them seal) so you can adjust tickover with the air bleed screw. I also never appreciate just how much movement there is in the throttle bodies when bolted to the head - the proper alignment jig makes such a difference.
Yes PI bodies wear the throttle plates a bit over time as the spindle shaft is bushed and can move laterally, not locked on bearings like a Weber/Solex/Dellorto etc. You remove that crust you end up with an idle speed you cannot lower!
