Hi guys, just joined a few minutes ago and was wondering if you could help me out. Went out to reno 2 weeks ago and rode a budy's bike and let him ride mine. Well after riding his 2006 RK, there was a huge difference in terms of power in his bike. It felt like it had a ton of power as mine felt really flat. He told me he changed the air filter, pipes and a few other things. But it made no sense, mine shouldn't be that slow, am at 5,000 miles and got it serviced already. What can i change to get more power
