You could move some of your code into the previous scanline 
(e.g. inc scanLine, sta HMOVE), but IMO your main problem is, 
that you are 'wasting' to much time with using subroutines. 
Each call needs addtional 12 cycles, which is ~1/6 of your 76 
cycles. So try to avoid JSR inside the kernel.

Have fun!
