      I noticed your not using the adjuster rod with the shift kit. How are you adjusting the tension on the rightside jackshaft chain? Nice bike also...

      The engine is so tight in this frame, there is no room to move it up or down. I will need to add a tensioner as I have done with other jack shaft builds. I have over 100 miles on this bike now. low and mid range work fine. High kicks off the motor chain every so often. Front derailier pushes it off. I need to work on that alittle.

      I now have almost 300 miles on Red. All 21 gears are working great. I added a SBP expansion chamber this week to take full advantage of "high" range. I have gone 35 mph so far with lots of throttle left in "high 5th", two gears to go.
