trialstime

I just purchased a 2 month old `07 Scorpa SY 250 R (race version not U.K. version) and I am looking for any feedback for performance mods and any tips at all on the bike. Im told the timing is already advanced from factory.Im told to go to a Main jet # 132.5 (from the stock #146) for better mid range. It still has the stock Champion plug.Was centre exhaust box rubbing an issue in `07?. "Any feedback on the bike overall is appreciated"as it was a toss up between the 07 Scorpa SY and 07 Sherco 290, so I thought I would try the Scorpa first for a year.
