I have the Diapason reflash and am happy with the difference in the lower gears, and, surprisingly, there is a VERY noticable gain in top gear roll-on acceleration which I happily discovered during a long trip on last Sunday. I took another ride during lunch break today, picked up some food at a convenience store, then set out to catch up with a friend who had just left the same store. I was wondering why the bike felt so sluggish :question: At the first stoplight, I realized the bike was still in T-mode.
Switched to S-mode and noticed to TC light going nuts in 1st and 2nd gear as the bike thrusted forward with new found authority and crisp response, briefly elevating the front wheel in 1st and 2nd gear...this was in TC-1. I can imagine how much fun those takeoffs will be in TC-2 or with TC off once the roads get warmer 8)
This is not meant to counter the guys who say the bike is plenty powerful enough in stock form..especially the U. S. spec bikes. To me, just the thought of having a restiction that limits the TB opening was enough motivation to get the mod done, but I admit I'm picky about that sort of thing... I want everthing the bike is capable of in stock form. I love the response of a bike with pumper carbs, and thats how this mod feels in S-mode; the response is immediate. Lazy commutes through stop-n-go traffice or smooth 2-up touring are made easy by just switching back to T-mode.
Again, there is no right or wrong and the guys who argue that the bike is fine in stock form have a very good argument...if I had never heard about the restriction, I would still be very happy with this bike. You can't go wrong either way.
