This guy knows a lot about suspension, this is a good video for everybody as he points out really obvious shit that I typically overlook and see many others overlooking as well.
HAHA funny you mention that. I just recently started watching some of his videos with him restoring a 2005 750 that his buddy picked up (I have 2 of them) during the one video he is evaluating if it's even worth fixing, and pulls off the right crank cover to manually roll the engine over and feel for compression, then he goes into some other things like looking at this and that, removing the air box (I did that at least, and had to remove the fuel tank and fuel on mine, it was horrible and the pump was dead) but anyway he's going on and on about checking it out..However, he does get a bit over the top sometimes. I don't feel a need to take a tooth brush to my brake caliper pistons after every race, but Dave does. The guy won't lead you wrong and your bike will be better off following his instructions. But how far down the rabbit hole do you want to go?
