How usful is re-gearing for drag applications?

Also note what which gearing does to your wheelbase. (shorter/ longer)
I like to run "quickly" around town and run a 14T FRT. with a 42T RR.

For the highway, I like to stretch the gears to 16T FRT. and 40T RR. (85 cruise)
With a 750, 16/40 might be a bit tooo much. Lot's of clutch to get going.
I used to run 15/38.

NOTE: my engine is now 1085 cc's W/ more cam, carb and compression.

Yes, gearing down in front and up a bit in back is what you need to do.

The easy way, and least expensive would be down 1 up front and up 2 in back so you can retain the stock length chain, unless you are planning on a new chain anyways then gear however you would like.

Yes, its all in your 60' so remember if you can't keep the front end down when you launch you are not helping your 60'.

My friend back home has an 06 GSXR1000 and was running 10.40's @ 138mph 1.6s 60' with stock gearing, now after 1down 2up gear change he cannot keep from spinning (launching at 7.5 to 8k) and lost a .10/.15 on his 60' and cant make it up in the 1/4 knocking his et's to high 10.50/60's, and lower MPH. They just had their last race of the year so he hasn't had another chance to get it under control, the bikes a wheelie machine now going down the 1/4.
