It's interesting reviewing service record after achieving 100,000km.
* Replaced front tire 4 times and rear tire 7 times. All of them are sport touring tires.
* Replaced chain 3 times.
* Replaced front and rear sprockets once.
* Replaced clutch cable once.
* Replaced low beam bulb once.
* Replaced front wheel bearings once.
* Replaced air filter once to K&N, should be permanent. Cleaned twice.
* Replaced front brake pads twice, never replaced rear.
* Has been running on octane 91 or higher for 1st year, then 87 since 2nd year. I put cheapest gas. No effect in power I feel and gas mileage.
* Has been following service schedule for 1st year, then not strictly since 2nd year.
* Adjusted (or simply checked?) valve clearance once.
* Motor oil and filter change every 12,000km. Filters are Tech2000 brand from Wal-Mart (I was told it's manufactured by Fram), costs less than $3. I've been using cheapest oil around $2/L/QT mostly 10W30, sometimes 10W40. I'll experiment with 5W30 this winter.
* Has been replacing followings every year: spark plugs (I started using copper ones instead of iridium since last year, have been always clean), coolant, brake fluids.
* Got flat on rear tires twice: once by a nail then repaired by a plug, another by unknown object repaired by a patch.
I have a feeling the battery or clutch plates may be the next one to die, but it's still going strong.
And it has been washed maybe 30 times?:sweat:
