Hi, have just bought a 2010 Classic here in New Zealand. I've found occasionally it won't go into 4th from 3rd and fifth from fourth. Thought it might have been my riding style as I've been used to thrashing high revving *** bikes but now I've read a few posts on here, perhaps its the detent spring as many have posted before me? Some are saying its a diy job, others I see say its a major issue. I'm no mechanic so it'll have to go into the shop. Love the bike so far tho.
