Hey got a few questions. I just picked up a Honda Cbr 600 f4 yesterday and the bike seems to run fine. the only thing is it has a scorpion exhaust but was cut shorter to make it look like a moto gp style exhaust. seems like everyone is doing it, it looks nice but I was wondering if this affects the bike mechanically at all. Also the bike has been down on the right side but not hard but the bar end on the throttle came off and there is no bar end. the hand grip does move I was wondering does this affect the throttle at all. Thanks for everyones help in advance and how hard is it to change the oil of the bike myself?

 

Exhaust should be fine. Simple add-on and no real harm to engine. Throttle should also be fine but I've always had bar-ends for safety. Just make sure the handle bar still has the internal weights. Oild change is super easy. Much easier then a car and great way to get to know your ride.
