Here comes the rain again

With 3 out of 4 events rained off this year it's not been the most successful year for drag racing, and it seems unbelievable that the day it rains has always been eliminations day rather than a qualifying day. Surely it's some kind of conspiracy!?
The Open sport nationals was not exception then, 2 days of pretty good qualifying weather followed by a day of non stop rain and no racing whatsoever. We were in a good position too, no1 qualifier for the second event in a row, and we ran a new best time and speed in the opening round, with a 7.53 at 172mph.
We had a few problems getting the bike to leave the line properly to, much like we did at the last event at shakey. It leaves ok then quickly starts to get tyre shake and wheel spin, then it starts bouncing until finally away it goes. I think the bike is too short really, I'm going to put a couple of links in the chain so the wheel can be pulled right back towards the end of the axle blocks. The extra 1.5inches should help calm it down a little and maybe stop it hitting the wheelie bars so hard.

As mentioned in previous posts, i'd created a nitrous graph to help cancel out a lean spike on the O2 trace of the racepak. It was just an experiment really but it has worked to reduce it and a little more tweaking should see it disappear completely. It's not a fix for the problem but it's a pretty good band aid for it.

There are now 2 races left in the ACU championship, and mathematically anyone could still win. However we are currently placed in joint 1st with Allan Davies. Because of the rain off, and with no more rounds at Shakespeare county raceway Allan has now secured the shakey club championship and we are runner up. The Santa pod championship is still to play for.
