Hello. I recently bought an ltr450 -08 which has problems at startup. the guy I bought it from has no idea what is done with the machine, which does not help. but when i switch on the ignition and press the start button it sounds like it wants to start but still not. it has spark and you hear that it is close to starting though but it misfire/ backfire. You can hear a smattering noise from the exhaust system. it has a vortex efi installed and i am wondering if this could be the problem? alternatively if it is the cam chain that is not standing right. because it sounds like it gets the spark at the wrong time or how to explain it. i am from sweden so have some problems to explain in english.
