I just ordered a bunch of stuff to start modding my '07 XR650L. I got a skid plate, a UNI air filter, magnetic drain plugs and temperature dipstick. I was reading on another post that the magnetic drain bolts may have issues... such as the magnet falling off etc. has anyone had these issues? I just hate to waste the money I spent on both the engine and fame drain bolts... they aren't cheap! One more question, where can I get oil for the UNI air filter? Is it best to use UNI brand oil, or will any oil (like K&N) work?
