Optimum gear ratio for 1/4 mile drag races?

Definitely run with less fuel in the tank.  I don't know what gas weighs (probably less than water?) but water is 7lbs./gallon.  If you went with only one gallon in the tank vs. 3 well...that's some good weight reduction.

How much time did you have in between each run?  I ask because your runs trended faster.  As eliminations progress, the time between each run gets less.  I've noticed that if I come in hot of the freeway, get through tech, and make a pass (lots of heat in the engine) my time is quick.  Then the bike cools for 30 minutes or so and the bike slows.  Then there's less and less time between runs and the bike keeps picking up.  

Just wondering if you saw the same thing.  If so, then idling in the staging lanes to keep the engine warm is probably a good thing for ET on the GS.  It's exactly opposite of what I do with my car - I try to keep all heat out - but if it works I'll do it!

Petrol weighs a fair bit less than water, about 3/4 that of water, so I'll try to run as empty as I can.

Time between each run was about 50-60 minutes, bit of a pain because I had to warm up the engine before each run. If I'd stayed my mates said they had another run 5min after my last run

I'm also in need of a new clutch cable, this one stretches a noticeable amount between cold and after it's been in traffic for a while. With the new cable, and a new air filter and rejet it should be good. Might also try a few runs with clutchless shifting, see if that'll shave a few 10th's off.
