I have super power sp 70 the bike has low mileage most of time its parked in my garage once i had issues of engine stalling overheating and mis firing to overcome those headaches i had to change the tuning of air/fuel mixture i was running on lean fuel mixture where engine was still overheating but not stalling then mechanic said its just an engine oil and dirty fuel tank is messing up so i have cleaned the tank spark plug changed the oil put up fuel filter to ensure that neat fuel is getting in carb infact i feel the ride go smooth as it should but the engine is still overheating i am running on stock setting of air/fuel mixture
