  • SV1000/TL Motor Swap

    Quoted from
    ************************************************** ************************************************** ************************************************** ******
    Although the SV1000 utilizes the same engine as prior 1000cc v-twin Suzukis (the precise displacement is 996cc), plenty of new technology was thrown at this motor for use in the SV. With roughly 300 changes, Suzuki describes the 90 degree v-twin in the SV as "thoroughly evolved and refined".

    Compared to the TL1000S, intake valves have gone from 40mm to 36mm in size, providing a big boost in low-end and mid-range power without much sacrifice in top-end power. The fuel injected SV is fed by Suzuki's dual throttle valve system controlled by a 32 bit CPU.

    This powerful computer brain keeps track of a number of performance criteria, including throttle position and even crank position, which contribute to more precise metering of fuel injection volume and ignition timing. Cam profile is also changed from the TL1000S, improving power output in the low-end and mid-range. Basically, Suzuki's goal for the engine was to smooth power output, without sacrificing much from the top-end of the TL1000S. Suzuki provided the comparison dyno chart illustration to show that they came pretty close to achieving their goal -- greatly improved low-end and mid-range, smoother transition from low-end to top-end, and only a minor loss of top-end peak power.

    Suzuki also made countless changes aimed at reducing weight in the engine, such as going to single valve springs (the TL1000S had double valve springs), aluminum valve spring retainers, smaller cam chain (which allows a related reduction in the width of the intermediate gear and idler gear), forged pistons (versus the TL1000S cast pistons), tempered conrods (30 grams lighter), etc.

    The SV1000 is the first Suzuki to employ a new aluminum cylinder plating technology called Suzuki Advanced Plating (SAP), which, essentially, results in a more consistent surface plating in about 1/5th the time of the conventional immersion plating method. Apparently, this results in reduced manufacturing costs, and reduced retail price.

    The six-speed, close-ratio transmission used in the SV1000 is identical, in terms of gear ratios, to that used in the TL1000S, except that the final drive ratio is lower. A lower final drive ratio means quicker acceleration.

    Since Zuki aint spent no money to refine our bikes, anyone ever thought of an SV/TL Motor swap to beathe a little "new" life that it prolly would have recieved if the interest/funds was available from Suzuki?

    Speak up!

    I would much rather keep the TLR-W motor I've got. If I want more "mid-range" I'll remap.

        Marketing speak for "castrated"?

        Although AMCN just dynoed one at 113hp, vs 118 for the TLS. Shame they didn't overlay the graphs to see the real world mid range, vs. the Suzuki marketing mid range.

          The output might not be a lot less but the potential is... single valve springs and smaller valves ? Since when had that been the path to better engine performance, unless your trying to build a Honda VTR engine

            i like the updated ecu and fuel injection, and the forged pistons.... but smaller valves?

              I have riddent the new SV.....and the motor is nothing compared to my 99 TLS. I can only imagine the difference between the SV and the 97 TLS. Don't believe everything you read in the magazines.... The SV1000 has had its balls cut off and is now an even more softly sprung, sport-tourer, with a mellowed out engine to match.

                the TLR motor you've got is way better. TLRs already have forged pistons, etc...what they keep comparing to is the TLS motor, which is still arguably a better motor than the new SV, certainly more potoent..except for more modern cpu and injection on the sv, which would be an improvement over the TL's, but you can tune your own bike so thats not a real issue.

                like the others have said, do some basic mods and remap if you want smoother low and mid-range, and you'll also be way ahead of the sv in top end after that.

                also make sure your tps is set correctly, that made a HUGE difference in the low end smoothness of my bike.
