Would appreciate any advice on how to correct a clutch problem with my 07 290.
When cold, the clutch works perfectly but after about 20-30 minutes running, it begins to drag and it becomes difficult to select gears.
Hydraulic system has not been touched from new and there is no evidence of fluid loss at the master cylinder.
Have tried changing oil to ATF and the crankcase breather tube is clear of blockages. Have also cleaned clutch plates with fine emery.
Any advice greatly appreciated.
