trialstime Posted February 9, 2008 Report Share Posted February 9, 2008 I just purchased a 2 month old 07 Scorpa SY 250R (race version not U.K. version.)and Im looking for any performance mods and any Tips at all. Im told the timing is advanced from factory. Im told to go to a mainjet #132.5 for better midrange.The stock plug is a Champion.What feedback can you guys give me on the bike. It was between this bike and a 07 Sherco 290 so I thought I would try the Scorpa. ALL FEEDBACK WELCOME. Quote Link to comment Share on other sites More sharing options...
peterb Posted February 9, 2008 Report Share Posted February 9, 2008 Hi Trialstime, I haven't owned a Scorpa SY250 but rode one in a 5 day trial in France (bit like the SSDT but far, far warmer and also with the most fantastic scenery) and have been working on a friends bike for some time now. The French bike was a standard 2007 model, I thought it worked well but was a heavy bike to change direction in dry, rocky sections and I didn't like the rear suspension action. The motor worked well but had too much flywheel weight, standard is approx 3,000 gms, my friends bike is down to 2,650 gms and this feels good. You can turn a step down on the OD of the ignition flywheel to reduce the weight. Gearing is fine. We fully advanced my friend's SY ignition by rotating the backplate though I feel this is too much, the motor is a lot more peppy but a little jerky now at the bottom end. There is a very good Scorpa site in Australia, might be called hellbikes or similar, there is a good section on tuning. Haven't heard of the centre box rubbing. The rear silencer (muffler) tends to burn your leg on road sections, good to fit a carbon fibre protector there. Also worth getting a protector for the exhaust pipe. Bye, PeterB.
