Petrol
Test drive task: Inspect the front fork seals while stationary and during the ride. | Detail: It is worth keeping an eye out for any weeping oil on the fork stanchions, as the F800GS can be hard on seals when ridden off-road.
Check this by: Cycling through all gear ranges under load during your test ride. | Detail: While riding, pay close attention to the gear changes; sometimes, worn selector forks can make finding neutral a bit tricky in these models.
While riding: Gently apply the brakes in a safe area to check for pulsing or fade. | Detail: In bikes of this age, it is common to consider the condition of the brake rotors, as heavy off-road use can lead to minor warping over time.
Check this by: Listening closely to the engine idle before and after your test ride. | Detail: A rattling noise from the top end can occasionally indicate that the timing chain tensioner may eventually require attention.
Usually marks the major service interval including valve clearance checks.
A common point where steering head bearings and rear shock linkage bushings may start to show signs of wear.
Consider checking the fuel pump assembly and cooling system hoses for signs of aging.
Regularly clean and lubricate your drive chain to ensure smooth power delivery.
Check the coolant levels periodically, especially if you notice the bike running warmer than usual in heavy traffic.
Inspect the electrical connections under the seat, as they can be prone to slight corrosion if exposed to moisture frequently.
Ensure the air filter is kept clean, as it is relatively accessible and makes a big difference to throttle response.
Monitor tyre pressure regularly, as the F800GS is quite sensitive to pressures for handling balance on-road vs off-road.
Estimated repair costs if issues arise
If this service is due, it involves removing the valve cover and measuring clearances; it is a routine task, but it requires a bit of labour time.
Depending on the bike's history, you might eventually need to budget for an aftermarket or refurbished shock if the original unit begins to feel 'soggy' or leaks oil.
If the bike occasionally struggles to start or runs inconsistently, it is common to consider the fuel pump controller, which can sometimes fail due to heat or moisture.
