Sprockets

15 and 42 Works well on a multi

 

I must look and see whats on mine, seems to work well enough.

 

My bike is running 15 × 41.

 

I run 14 x 42, accelerates pretty well...

 

Ok, I tried both one tooth down on front sprocket, and then two teeth up on rear sprocket (GT1000). Overall effect was very similar in giving livelier acceleration in lower gears & being able to use 6th at a slightly lower speed.
