Hi all , new to the forum b/c I'm thinking about purchasing a new 07 VN2K but I'm a little concerned about a few issues about which I've read in my research -- namely , back wheel/belt chirp and oil leaks . Are these common problems , and are there any other ? Also , I know the bike has hydraulic lifters but are they 100% maintenance free ? The reason I ask is that the big Yamaha cruisers have hydraulic but still need to be inspected every 20,000KM . Thanks .
