Sprint 955 2002 model tips needed.
Please excuse my general Triumph Tripple Ignorance, not really had time to get to know it that well yet. I normally buy stuff already worn out and rebuild it hence you get to know stuff quick. My newish purchase is a 2002 ST Sprint with only 12k on the clock so doesn't need that much yet. First thing I noticed was how snatchy the F.I. system worked when rolling on and off the throttle. I was advised that its probably due to all the emissions junk fitted for the German market so started to look for a new stealthy end can so as not to attract attention from the local plod.
I decided on a can made by A16 road and race supplies in UK. The can looks very stock just a bit shorter with no badge (or Cat) weighs much less. It's not loud and runs fine with the stock map. The bike is much better and theres no popping on the over run which it used to do with the stocker. My question is, do you have to adjust the mapping to match the new end can? Also can you remove the secondary air system from the bike and will it make any difference?
