Well I returned to speak to the manager and the mechanic.They were helpful and insisted to demonstrate the issue .I could actually hear how loose the cam belt was when he covered the exhaust with his hand to dampen the engine noise . Bike is pretty loud and has a straight pipe. Previous owner used it as a track bike. ... it's rather concerning that it had worn so quickly netherless it will be replaced. Going to replace the exhaust with a Yoshi or something decent and get it re-mapped once everything is running perfectly. Thanks to everyone for their input!
