2005 outlander fuel issues

Hello all, This is my first post here. Been reading allot of threads for quite some time but having trouble with my outlander so I thought it was time to join. Its a 2005 bombardier outlander 400. I use it mainly for hunting and just giving my little grand daughter a ride. Its always been garaged and not many hours on it since I bought it new. Only trouble till now I had was the voltage regulator I had to replace. I hear that’s common. About 6 months ago it would only run to half throttle like it was starving for gas. I took it to a local guy and he cleaned the carb and got it going but he said it looked like it had pieces of inside of gas line stopping it up. I rode it the other night and its doing the same thing. Tried it again today and now seams like its wanting to flood and running bad. I called the dealer where I bought it new and they said new fuel lines would run about $150. Does it take special lines? I love working on cars but never worked on a motor cycle or atv. Is it a hard job to change the fuel lines and take carb off and clean it? Is this a common problem on these bikes?
