I just recently purchased my first dirt bike (used) and this model came highly recommended. I have a few concerns that I'm hoping to get some feedback on. 1. Upon my first oil change I discovered some metal flakes in the oil filter and metal shavings in the oil. Has anyone experienced this and if so, should I be concerned? I have a friend with the same bike and he insists that this is normal but I'd like to get a second opinion. 2. My first ride out I found that my clutch is in need of replacement. While I was out on the trails some experienced riders set my idle a bit higher to compensate. I stalled quite a bit and then my bike began to overheat. I'm told this is due to an air flow issue with the higher idle setting. I haven't changed the plug or the air filter so I'm wondering if this may be a factor. Any suggestions for me here?
