My brand new DL 1000 Suzuki V Strom hiccups around 2700rpm in 2nd gear and surges between 3000 and 4000rpm in 3rd. Any comments, cures?

Due to environmental issues the V-Strom DL1000 is adjusted lean at low rpm from the factory. This is a source of complaints since the beginning in 2002. The new K6 model is said to have overcome the problem with a new ECU programming. For the others there is only the way to reprogram the FI with the help of adjusters like the Yosh Box, the Teka Adjuster, the Techlusion Adjuster, or buyng a Power Commander. Make sure you are using regular gas, sync the butterfly valves, and adjust the valves before changing FI programming. Regards Peter

I just bought a 650 V Strom and it does a little bit of the same thing. At that RPM and gear you are probably going about 25-35 MPH. Lots of bikes have surging at low speeds. Mine is not all that bad so I suspect yours is not that bad either. I can attribute most of the "surging" to bumps and irregularities in the raod surface that you will feel at low speeds but not so much at higher speeds. My recommendation is to go a little faster or change gears to see if that cures it. My experience is that at some speeds I just hit the rhythmic bumps of a street just right and it feels like surging but it really isn't. Plus, as you are bumping along your wrist will rock back and forth on the throttle making the problem even worse. So try riding at different speeds and on different roads to see if this helps. True surging is most likely a fuel injection mapping problem. The only way to fix it is to reprogram the way the fuel injection works. This must be done by a dealer or a really sharp mechanic. Oil additives will definately not help. Coolent additives will also do nothing except waste your money. Change your coolant in accordance with manufacturers recommendations and use a coolant WITHOUT silicates. Silicates are abrasive particles (sand)designed to keep automotive cooling systems clean but they damage small engine water pumps. Water Wetter is a good product designed for use on the race track but does not contain the antifreeze components you will need for storage over the winter. Slick 50 is also a big waste of money. It has been scientifically proven not to work and Penzoil has been required in court challenges to stop making claims that their Slick 50 Teflon additive is a miracle cure for engines. The best thing you can do for your engine is to use a quality 100% synthetic motorcycle specific oil and a QUALITY filter like OEM or K&N, Hastings and a few others and change the oil and filter at recommended intervals or sooner. Stay away from oil additives. Hope this helps. Peter

Take it to the dealer to have a quick look at it, it could just be either a bit of running in stickyness or they forgot to check something was tightened up properly before you got your hands on it. Failing that, try an oil additive such as Slick50 in the oil tank, a fuel additive such as Redex in the fuel tank and if the engine's water / liquid cooled (spot the bike expert) stick something like "Redline Waterwetter" in the coolant tank... and it might feel a bit better (and last longer). ~ JD
