A list of things I did to my 05 FS650e supermoto shortly after buying it in April. It had 130 hours 3000 miles on it.
I bought and had Dale Lineaweaver install his jet kit.
I got softer seat foam, a Gutz tall soft
I swapped the huge tailight for one for a 2006.
I installed Cyra CRM handguards, and ProGrip Rally grips.
Changed the coolant to a 30/70 mix of coolant/distilled water with some water wetter.
Changed out the old brake fluid.
Bought two new tires.
Replaced a leaky waterpump seal at 180 hours.
A month ago, at 230 hours, a valve spring broke. I bought and installed new valve springs, valve seals, a head gasket, and a new timing chain.
At 8,500 miles 260 hours now. Never raced it, but thinking about it. I've got to get some leathers first.
Edit: I bought a new chain and sprockets a while ago and another rear tire
Oil changes every 10 hours, with filter every other time.
Valve adjustment every 30-40 hours. Would check every 20 hours on a low hour bike though.
