All YAMAHA partsYAMAHA YZ 490
The YZ 490 hits like a sledgehammer. Big-bore two-stroke, air-cooled, no manners. Get carb jets and engine gaskets spot-on or the thing runs hot and lean. Check reed valves every few rides. Eyeball the exhaust mounts too — vibration shakes them loose before you notice. Old iron, still mean when it's set up right.
