It has taken awhile to finally get these results posted. On March 27 the timing mark cover came off and ran my bike out of oil in a desert race. The intake cam and head jounal took all of the abuse. Engine Dynamics did a great job of fixing the head and I decided it would be a great time to replace the exhaust cam for the auto-decompression in addition to the trashed intake, both are Hotcams. After dealing with some issues with the head, Mike's at Engine Dynamics customer service is by far the best I have ever delt with and I highly recommend his services, I got the engine back together June 19. On the ride to break in the cams the two biggest things I noticed were it starts like my old XR80 (read very little effort) and the bike seem to pull harder because I was constantly trying to shift up from 5th. Unfortunately before I could really exploit the full potential of my new found power band, I hit a log in the wash I was riding that sent me over the bars and head first into the dirt. It took a little while to recover from getting the wind knocked out of me but I made my way bike over to the bike. It was very painful and took all of my strength but I was able to get it upright and it started within a half of a kick. The good news is the bike suffered no damage and I really love the new cams, the bad news if I fractured two vertebra and crack a rib. After a fun visit to the hospital and a couple of nights stay my injuries showed to be non threatening to my spinal cord and I should be good as ever when the fractures heal. The Hotcams as a set get just watch out when you release all the power on unsuspecting logs and avoid doing my impression of a post hole auger.
