My K1200S test ride, recent comparo's sparked my interest

[spamanglenn]

my bike is pc3 mapped for my 4into1 and airbox.Last night i trialled a tre on my bike and found the following.The snatch from off/on throttle was 50% better and more consisitent for each gear.A big plus in my book.I also found the exhaust was quite a bit louder at cruising speed,and idle strangely enough.This is a negative for me.The torque curve in the mid range felt weaker as well.This is all without fuel mapping the tre with its new advance curve leaning my air fuel out and worsening performance in my case of an already mapped fuel curve for my modded bike.From experience i also know leaner mixture means a louder exhaust.So for me i will get the bike air fuel checked before and after the tre and decide whether i can regain my midrange,quieten the exhaust and enjoy a less snatchy throttle in 1st and second gears.As faster says if you are not going to fuel map for the tre or atre or whatever don,t fit it.
