what he said..they can be touchy about there oil. it has to work hard doing engine/gearbox duties all in one.Trouble shifting gears, which indeed he is correct. And often on the SV too much oil can cause these sorts of issues, but when I had just got the bike I found all sorts of half gears and clunking sounds but they all seemed to stop happening after a while. Same when I got the R6, you get used to how the machine works.
