Torque figures for this job
General ranges for these fastener classes. Confirm the exact figure in the service manual for your model and year before final tightening.
| Fastener | Range | Note |
|---|---|---|
| Sump drain plug | 20–30 Nm | Always with a new crush washer. Alloy sumps strip easily above this figure. |
| Spin-on oil filter | 12–20 Nm | Oil the gasket first, then roughly three quarters of a turn past contact. |
| Cartridge filter cover bolts | 9–12 Nm | Tighten evenly across all bolts; a cocked cover weeps oil. |
| Oil level inspection bolt | 8–12 Nm | Small M6 into alloy — snug, not tight. |

How to replace engine oil and filter
1. Warm the engine
Run the bike for three or four minutes so the oil drains fully, then stop it and let it stand a minute.
2. Drain
Remove the sump plug and let the oil drain fully with the bike upright.
3. Change the filter
Remove the old filter, oil the new gasket, fit hand-tight then torque to spec — usually around 12-20 Nm.
4. Refit the plug
Fit a new crush washer and torque the sump plug; overtightening strips alloy cases.
5. Refill
Fill with the manual's quantity of JASO MA2 oil, run for a minute, then re-check on the level surface.
6. Record it
Note the odometer on a service sticker so the next interval is not guesswork.

Around $125 at an independent workshop including parts, and up to $200 at a dealer with premium parts. Doing it yourself costs $60 in parts and consumables plus about 40 minutes.
Can I use car oil?
Not on a wet-clutch motorcycle. Energy-conserving car oils contain friction modifiers that cause clutch slip. Use a JASO MA or MA2 rated oil.
Is a dealer oil change worth the extra?
Only while a warranty requires stamped service history. Otherwise an independent shop does the identical job for markedly less.
Can I use car oil in a motorcycle?
Not safely on a wet-clutch bike. Energy-conserving car oils contain friction modifiers that cause clutch slip. Use JASO MA or MA2 rated oil.
