Where do you check the oil on your 660 Yamaha raptor?

To check the oil on your Yamaha Raptor 660, first, ensure the bike is on level ground and that the engine is cool. Locate the dipstick, which is typically found on the right side of the engine. Unscrew the dipstick, wipe it clean, reinsert it without threading, and then remove it again to check the oil level. The oil should be within the marked range on the dipstick for proper operation.
