I have been a two stroke rider all my career and know pretty much all you need to know about them. But after leaving the 125s i purchased a suzuki 250 four stroke. I pretty much know nothing about them, only how to change the water, air filter, oil and oil filter. Is there anythings i should do to maintain my bike each week after riding? I dont mind how big the job is id just like to know as i want my bike to be in top condition.
