Hmmmm it is a virus, the heat thing gets into every thread,,, as for the shift issue, be more positive with the shift and don't use the clutch on the up shift after 4000 rpm, the quick shift and clutch action can conflict which feels like slip or over rev... Make sure u don't have the shift leaver set too fine... I found that on the odd occasion on fast changes of direction I can catch the shift rod with my foot and the engine will cut out... Had the same issue on the 675R, takes a little getting used to if its ur first bike with a QS... Doesn't help if u use race shift at the track and. Switch to road shift patten on ur road bike... Infact its a pain in the .......
