At end of first ride noticed what seemed like fouled plug. Next ride changed plugs. 25 miles all good then lost power at 7000 rpm acting like not running on all 3. Stoped inspected plugs clutch side seemed a little wet changed that plug good again for a short while. All fuel drained fresh added, carbs inspected cleaned, (nothing found),comp 115/118/118! Any ideas why this is happening???
