Hello everyone! I'm new to the forum and I was hoping you guys might be able to give me some advice on something. I just bought a 2008 M50 about two weeks ago and I've put maybe 300 miles on it already. I bought it with about 9100 miles and it seems to run good. It's my first bike so I don't know a lot about motorcycles in general, but I'm learning as I go. Everything on the bike is stock (according to the last owner) except the air cleaner. It appears to me the he modded the stock air cleaner to fit an Edelbrock air cleaner meant for a carb on a car? I'm not 100% sure on this so I'm hoping you guys could help me out. I've attached 4 pictures of the air cleaner with and without the filter attached. I would really like to replace it with the stock air cleaner and a K&N high flow filter, but I'd probably have to pay someone to do it. I'm not sure if he had the bike tuned after doing this mod or if he just slapped it on there and off he went. Any information or advice anyone might have would be appreciated and feel free to fire any questions at me that you might have.
