Hi, I bought a Triumph Daytona 1000cc new in 1992 and my son has the same, but the 750cc triple also 1992. They go ok, but when hot in towns at traffic lights etc. they bog down and missfire as you pull away. Once you are back on open road and the temp goes down they run ok. It is only as the bikes are getting older that it has done this. Have changed plugs, ballanced carbs, and usual servicing but still does it. Any Triumph owners had the same problems and got it fixed. Anyone got any ideas as my son is deaf and can't hear the engine and sometimes stalls it as he pulls away. He said if he can't fix it he ain't going to ride it anymore.Must be some clever people out there that can help me. HELP.
