Advice desperately needed!!!

Hi everybody my name is Patrick but known as "Pappy" I am the proud owner of the ONLY Triumph Bonneville T100 in the Falklands.
Boy does she turn heads!! I am flying her to Southern Chile in May'ish
next year to do a South American tour for a couple of months over our
winter. But I am becoming a little concerned because lately she has started to play silly buggers with me. After running for 20 minutes or so she starts to run a bit rough,then on 1 cylinder,backfires a bit and stops. She then won't start for a while and then suddenly away we go again just to repeat it all,BUT! not every time I run her. It's got me baffled,sounds and feels like starvation but all's clean inside. Could it be electrical? I recently fitted a lockable fuel cap,and a Scottoiler which I tapped into one intake. Could the new(Triumph)cap possibly not be letting enough air in and/or has the oiler upset carb balance? One thing you Great Guys out there must understand is that here in the Falklands there are no m/cycle mechanics or dealers at all so there is absolutely nobody to ask for advice over a beer, especially when you own the only REAL bike in the country. I do have more queries but they can wait, thanks everyone, cheers, Falklander.

Sounds like fuel starvation. the vent pipe from the tank may be kinked, easily done when replacing the tank. Or there may be a second pipe that goes to a filter used in us models. that can block. ( throw it away). My tiger developed the same problems and the mechanic just pulled the second pipe off and all was well. The way to find out is to ride around with fuel filler cap undone...

as grey as gandalf but not quite as old

Welcome Falklander! You and your Bonnie are the first from the Falklands that I know of. Check out the Twins forums for advice.
Although, nehpetsthegrey may very well be on to something. Good Luck!

Thanks for the replies guys. Had her out all afternoon yesterday and she never missed a beat,soooooo strange! Will be out of touch for a while as I'm working up in the mountains
building a road for the M.O.D to their firing range and our accomodation camp doesn't have
any internet, so will be posting next time we're in Stanley on a break.
Ride safe,
