| By the way, and taking into account Shazaam's comments which I do not disagree with in any way, I ran a Suz### (system crash) TL1000S for over 5 years, which I gradually developed into a really fine bike.
One of the last mods I did to it was to comprehensively modify the airbox and induction path.
The TL's ram air is not direct and the flow turns through 90 degrees twice before reaching the filter. Also, the left and right air flows meet head on and the entry into the (fairly large) airfilter is partially obscured. Finally, there is a quaint flapper valve mechanism in the induction path, which is there to make your coffee frothy or something like that.
My mods introduced smooth curves in place of the right angles, removed restrictions into the airbox and air filter and installed the flapper valve correctly in the rubbish bin.
I didn't get a chance to dyno the bike before I sold it to join the World of Ducati, but my arse-dyno was very aware of a serious improvement in torque in the 3 to 5,000 rpm region. The TL was never lacking in that area before, but after these mods it became a bit stupid. It also started to make a proper honking noise at large throttle openings.
Top-end was more difficult to judge as the bike had always dived for the rev-limiter.
I guess the Frappachino valve may have restricted air intake in order to pass noise emmisions tests, but the extra air getting in after the mod was very effective.
In case anyone is interested, with a full Akro Ti-conical system, PC, K&N and a few little twiddly bits it made 119 rwhp and 72 lb/ft.
I now own a proper bike and hope I will not be judged too harshly for the confessions above.
