Finally got the engine completed and installed in the chassis. It fired right up but was running rich. I leaned it out and it sounds okay. I'll tune it again once we get to the drag strip in Atlanta tomorrow. Hoping for some 8.90's but the gearing could be slightly off. I'll probably just enter it in pro ET to get a baseline.

Well, things didn't go as planned at the race. On the first pass down the track the bike started the huck-a-buck routine. Seemed to be an intermittent electrical issue. It only ran a 5.89 in the 1/8th mile and a 10.00 in the 1/4 mile with me shutting it down about the 1000' mark. I decided not to work on it at the track and concentrate on racing my Honda in the street ET class instead. I'll roll the bike out of the trailer tonight to see if I can determine whats going on. I feel its in the main power supply someplace because I noticed the shift light bounced on and off multiple times- this indicated a loss of power from either the main toggle switch or from the wire leading from the battery. I'll get it worked out because I have another event at the end of the month and want to race this bike.
