The T100T Daytona for 1969.

 

This is my 1969 Triumph T100T Daytona shortly after I got it. I use this bike most days to commute to work and it serves me well. The original colour scheme for 1969 is Lincoln Green and white but it had all blue tank and guards when I bought it. I have since painted the mudguards silver leaving the Triumph type stripe up the middle. The bike is also currently fitted with one Concentric 626 Carburetter. I have the other and will get round to running with 2 as it should be in due course. I've also got the original seat back on at the moment although it looks fine with the older style seat in the pic. It runs pretty well with the single carb though. I can't fault this bike.

When I bought it I met the seller in Durham, he'd driven it up from near Hull. I then rode the rest up to Edinburgh. When I arrived it still ticked over as sweetly as you like. A bit of a surprise especially when I'm used to my Trident which never seems happy at idle. One carb instead of 3 is a lot easier all round, although I'm increasing the main jet as its currently under jetted.

I intend to keep using this bike to travel to work and don't grudge spending the necessary cash to keep it on the road. Tax free, low on petrol nippy in traffic (almost as good as the bicycle). It is bored out to +50 so the barrels may not have much life in them. Any spare top end bits out there? Please email I might be interested. I think a rebuild is not too far away. The only downside to this bike has to be the 4 speed box. The points mentioned in Steve Wilson's excellent book 'Triumph Motorcycles' I have found to be really fitting to my bike. He mentions a jumping out of 3rd into neutral. Well the first time I became aware of this was riding up from Durham overtaking a line of cars at about 70mph approaching a bend(OK with hindsight it was poor riding). Obviously I'm here to recount the tale but I have to say my right foot was poised for action at all times for the rest of the journey.
