CRASHTOWN

this bike is fuel injected? how would i go about cleaning it?

I have a 2007 suzuki LT-A450X 4x4 which has two problems which i hope someone has an answer to help me out. First the bike has a hard time cranking up has new battery and turns over just fine but it takes turning over many times to start up and now i need to spray starting fluid in the air filer to start and it seems to like being pull started instead of the starter ??? Second when i do get the bike cranked up and drive it at high speed it pops out the exhaust??
