Frank Adams, testing done?

Frank,
The last post I remember seeing, you were heading out to test a 41 & 42 tooth rear sprocket. Did you find out anything or have I missed the results? I was curious as to your opinion. Will the 41 out pull the 42? I have read where the 42 will get the jump in a roll on, but the stock 40 will reel it back in. Just curious. Jack.

The only testing I've had the opportunity to yet has been with just two combonations on a stock motor Busa. Which were 16/40 & 16/42. I didn't go any further yet because the 16/42 showed a 1 tenth gain in the 1/4 mile.

This Busa(16/42) was running through the traps around 10,000rpm in 5th gear.

This is as far as I've gotten so far but I'd still like to see what the 17/42 combo does?!
