900 Trident ?
I had a new XJR1300, bought new on a '56 plate after Len Manchester Motorcycles in Melton stole my 750 Trident (really!). the Yam never ran right, had a huge flat-spot in the power curve just above tickover, felt cheap and built down to a price (a low price, that is...) it wouldn't start when hot and the finish was a bit poor. Having said that, it was all-day comfy.
if I was looking for another bike like this I'd forget air-cooled and go for either a Honda CB1300 or a 900 Trident. you can pick up a really nice 900 Trident for less than £2,000, use some of the spare cash to upgrade the brakes to Daytona spec (310mm floating disks and 4 pot calipers) together with Sprint or Daytona 3 spoke wheels (17" front and back) to give you a better tyre choice.
mine's also got Speed Trip (old style, 900) rear brake rod and longer gear linkage to allow the footpegs to be moved to the Sprint / Daytona positions - better for my long legs and cost about £20. plus Sprint-Sport lower clip-ons.
55K miles on the clock and no probs. it blew a bulb once, i think.
The CB1300F is also a much better prospect than the Yam, but it's not air cooled.
This is just my oppinion obviously - I've got friends with XJRs who absolutely love them, and I know people who've had Triumphs who didn't like them - fair enough!
Me, I like to be able to tinker a bit and change a bike so it suits me. I love the way the bars and pegs are so easy (cheap!) to adjust on the older Triumphs :)
