Thanks for the feedback bodine. I think Ill take a chance with the Barnett. From my own experience and everything Ive read about the quality/longevity of current and past options available its hard to imagine it could possibly be more problematic. At any rate at 73 canadian dollars delivered to my door its by far the cheapest option available. My only previous experience with Barnett products was one of their clutch plates added to a friends brand new 1971 810 Paul Dunstall Nortons clutch in a futile effort to prevent persistant clutch slippage at higher revs,particularly in 4th and 5th. Not a comment on the barnett plate so much as the pathetic Norton design. The problem was resolved by another problem when the dogs on one of the gears (I forget which)on the quaiffe sheared off in another spectacular display of poor quality/design leaving the bike once again as expensive roadkill....I could write a book about the failings of that particular bike! Great fun to ride but a frustrating never ending melange of mechanical woes.

One thing about Barnett plates on Tridents: there is very little slippage. In fact if you are trying to slip the clutch it is difficult, They are on/off switches.

I was a young hot rod at the time, so it didn't really bother me much. Some time later I had an oil leak into the clutch area which fouled the clutch plate. I replaced the plate but I don't remember what I used.

Had a Barnett in mine when I bought it. Worked well enough, no issues, but when I opened the clutch and saw it I was horrified. The spline section was about half the width of a standard plate, and the splines were almost gone. Replaced it with a Hyde sintered plate, which so far works perfectly.

The worn spline symptom can be a problems with any clutch plate in a Trident. It is a symptom that you got one of the T150's where the inner and outer rear chain weel needle bearing housings are out of alignment with the transmission main shaft (and its bearing housings). The worst one we serviced they were a bit more than .100" plus out of alignment. This forced the clutch to try to act as a universal joint. The weakest part in the whole it of kit was the splined pressed steel sleeve riveted to the plate. While most of the ones we had problems with the customers would get somewhere around 1,000ish miles, the one that was .100" out of alignment struggled to get past 600. This was in the period where BSA was going broke shortly before they pulled the plug on the BSA brand.
