charlesj replied to pandrewdee4t's topic in 250-530 EXC/MXC/SXC/XC-W/XCR-W (4-Strokes)I have a 520 MXC that is doing the same thing. Only 2nd gear. It has progressively gone worse over time. I replaced clutch pack, flushed hydraulic lines, and using correct synthetic oil. No heavy wear noticeable on shifting fork or drum. Any help would be greatly appreciated. I do not want to split the casings!
