  1. We have a KX85 that my son races arena cross with. We've notice the last couple of races that were the front pipe meets the exhaust it's starting to leak oil. We are running Klotz pre-mix at 40:1. I wanted to see what everybody that about the plugs below. The first two pictures are what the plugs look like with three races on them. The third picture is what it looks like with two races. The last one is what they look with one race on them. Also as the temp start to rise outside we are noticing the bike wants to bog. Looks like we may need to Jet it but wanted some suggestion on which way to go.
