Hi all, just picked up new 520exc yesterday Was wondering how others have run their bikes in. Plan to do oil anad filter change ~ 150kms. Dealer wants it back ~400-500kms for scheduled 1st service. How long before she can be opened up and allowed to bark. Have been cruizing (no quick throttle changes) up and down gears to around 1/3 throttle. Dealer has rejetted, raised gearing and removed exhaust screen. I think this bike has potential but have'nt opened her up yet.
