Hello, where to start. I've just purchased a Beta evo 300 4T. What kind of tyre pressures should I be running front and rear? I've been told you don't soak and rinse the air filter in filter oil you just give it a light spray, is this right? How much play shoud there be in the head stock? I Want to do an oil and filter change, I'm told these have 3 filters to change? Any recommendations on oil? Finally, roughly how long should it take for the rad fan to kick in? Thanks in advance
