B, now not being smart or anything but how does removing the secondarys add up to more speed, their removal may change throttle feel in the midrange area, but wide open is wide open and when the bike is wide open the secondarys are wide open and the blades do not present any more air flow resistance then the throttle shaft, unless you are removing the shaft too?? The secondary plates are there to provide a smoother transition and a consistant air flow when the throttle is opened quickly. If you are always in the proper gear you may not notice it but shift up a gear and snap the throttle open I think it may result in a momentary hickup until the air speed increases enough to allow the engine to use the extra shot of fuel you just threw at it. This momentary hickup (lag) may give you the impression of more power because when the engine catchs up it will launch you and the bike quickly down the road. Using your car or truck as an example, you whack the throttle and the computer sees 100 percent throttle request the system has to make adjustments,to fuel, timing and a down shift of the transmission, during this time lag the engine is allowed to free rev then the down shift occurrs and the power hits and if you have enough power the tires spin and you are moved down the road very smartly. Again not being smart just asking. Have you or any of the others tried the Timing Retard Eliminator, the 1k has the timing retarded in the first four gears, if you use one you may have to use 89 or higher octane fuel all the time but it does wake them up.
You are not being a smart ass....just intelligent!:mrgreen: Actually I have zero
lag when I crack open the throttle, with the butterfiles out. I have more of a smooth transition with any kind of throttle response, as far as I am concerned. Pulling them out pretty much does what a TRE does for "free". I can now redline in any gear if I so desire, as well as having a "full" top speed capability. You cannot achieve this without pulling the butterflies or installing a TRE. You lose the overdrive light for some reason, with a TRE installed as well. With the secondaries in WOT is not WOT, actually the ECM will have the secondary shaft close the butterflies which restricts the power and top speed. The primarys can still be open, but the secondaries overide them. Pull out the secondaries and you continue to build speed and power.
I am not an advocate "usually", for going and changing a design from the factory. But.....myself and MANY
others feel that the secondaries really serve no positve purpose, and all they do is tame down the potential of the engine, and maybe help with emissions. With my secondaries out, FI system properly adjusted, and baffles OUT of my Leo Vince exhausts, my 1000 pulls like a freight train and runs like a scalded dog. It is faster, revs quicker and runs better than ever. Haven't we talked about this all before????
I still do need more fuel sometimes, cause she will buck and sputter at low RPM's sporadically
. Usually happens when the weather is warm and I have my baffles pulled out. Baffles in and she runs great, which proves that I need a bit more fuel at the bottom rev range. I will fix that eventually!!!;-)
You sound like you work for Suzuki, I'm really impressed!!!!!
I am sure that you will
convince some people, with your excellent observation.
