Hi again, the problem last time was exhaust related and came about following repacking the end can. You fixed this problem, by repacking and the bike ran okay for a while but the same issue has returned. I would firstly suspect the exhaust again as the original problen manifested a while after repacking which sounds like the same circumstances as now. My dad had a friend who worked for the AA, he used to say most cars break down through a lack of neglect. In other words if it aint broke don't fix it . I suspect that repacking the exhaust has caused a problem which takes a little while to show, it may be that the packing swells or moves when it has been used for a while and causes an obstruction. My advice would be to have another look at the padding.
