But what's more significant for me is that it increases the Torque to a 16.1 kg-m value... I've already test driven a Yamaha MT01, & despite that it throws at U only 15,3 kg-m of torque, I was literally dumbfounded!!! By that there bike... To the point that it's been the very first "dream bike" of mine... When I've learned that there might be something out there that's "even better"!!! I became a T-bird lover!!! A "Big-Bore" T-bird lover BTW... I've already test driven a T-bird in it's stock version, thus in it's only ~14.6 kg-m version... & I loved it too... My recent bike, the Suzuki GSX1400  as one of the most torquy motorcycles available on the market, before the arrival of the MT01 & then the T-bird, of course... produces all of 12.8 kg-m... So I do know the difference...

| | Posted : 09 Sep 2010 - 19:06 Post title : Re: Question for 1600 owners that went to 1700 (Re: Thatch) | | | I thought it best to dig up my old post on my first long ride after the install. So I'm not speaking from distant memories of the 1600, here is what I said following my trip to Florence (about a 200 mile trip)
As for the BB kit, I don't notice any change in responsiveness. I got that with the air filter and pipes but not with the kit. What I did get with the kit was a whole lot more pull. Yank on the throttle and it will slide you off the back of the seat where as before it pulled hard but predictably. The bike now feels a bit more wild. It's not that the fueling is off or that you don't know what you are going to get with each pull but that now theres enough to hurt you if you're not careful and I likes it!
The bike also pulls past 100 more than it did before. Some of that is due to the pipes. There was a bit of a dead zone in the stock bike around 70 and up where it seems to shallow out a bit in power. The pipes really opened that up, but now with the kit the power in that area is much greater as well. This is a blast to play with but a bit dangerous as well. As stated I discovered myself above 100 about 5 times during the trip. Before the kit I always decided that I was going to hit the ton for what ever reason. After the kit, I find myself already there with no previous intent.
Lastly the tone. The tone of the bike has dropped nicely after the install. You can immediately tell the difference (at least with my setup). The tone is deeper and the idle seems a bit slower (I'm not sure that it is but) it seems to have a bit more of a lope to it than before. Which knowing what the new cams looked like makes a bit of sense.

The improvements are across the board with the bb kit, but by far the change that impacts you the most is the torque. I remember leaving the shop and grabbing the same amount of throttle as I always had for a 'spirited' take off and finding my ass on the top edge of the seat as I was thrown back on the bike. I recall in the first week doing my first (albeit short run) wheelie on the bike when I got on it in 2nd, surprising the hell out of myself. The difference in bike is quite obvious and it really changed the whole personality of the bike. Of course there is more HP and on the top end it does run harder and accelerate faster, but you spend so much time in that 1500-3500 range that
the torque is by far what you experience most.

torque * RPM * constant = hp
87.5 lbf-ft * 60 rev/min * X = 1 hp
X = 1 / (60 * 87.5) = 1/5250
torque * RPM * 1/5250 = hp
hp = (torque * RPM) / 5250
Seriously though heres the Link

| | Posted : 10 Sep 2010 - 12:34 Post title : Re: Question for 1600 owners that went to 1700 (Re: daz) | | | The factory numbers, supposedly with the std cans and air filter in both cases, are:
1600
Power: 85 HP @ 4850 rpm's
Torque: 146 NM @ 2750 rpm's
1700
Power: 101 HP @ 5500 rpm's (+ 18.8%)
Torque: 160 NM @ 3000 rpm's (+ 9.6%)
The power and torque gain is the reason why I had the BB kit installed on my 'Bird upfront, after having had the privilege of testing the std issue  , reserved for a "preview" by the Swiss trade press, in Aug. '09. It's a very "real" gain, BTW. The proviso here is that it mostly of not ONLY manifests itself as from, say, 3800-4000 rpm's.
Which I personally find most enjoyable
