Mate, no worries. I know that many will at some stage experience problems due to dealers nearly knowing nothing about the variable valve lift 250Vs.
I have a crook relationship with my local dealer, problem is they try to get me to leave the bike with them for work but I know they don't even have a manual for the model I have. So in turn I have had to learn a lot, but being a mechanical type of dude I am finding my way around the masterpiece the 250V is and am now passing on that info to help all.
Main driver is that the bike is just such fun
