KX Guru Racing

Ok, the compression is dialed in with the new head installed. The chassis is set for height. I changed the bar style to give it a bot more stability at high speed. The steering stem bearings loosened up a bit since I built this bike so I made that adjustment. I bled the front brakes so they grab a b...

9-16-22 Update. Bonneville was a bust this year as we were rained out. It's hard to hit a Land Speed record with 4" of water covering the lake bed :shock: Anyhow, testing and tuning continues... Which is good. We have picked up a few more miles an hour with changes to the crank, muffler packing, and...

I wanted to verify that my 19-22 KX450f forks would fit on my custom clamps.
Very nice...
