Thats how it always goes, lol. Now all we need is a TNT pipe to complete the ski.

Update on this. By doing more tuning of pipe, and closing low screws some we were able to get 6800rpm. I left it there and let my son finish last race weekend in Sylvan. 44's are off now and we are going bigger.

gp1200 is 44mm correct?

On a kawi 1100 b1 swap, can 2x Engine side couplers be used from kawi on a gp760 midshaft? Or must i buy the Ada coupler set?

Thanks for all the input. With our last race weekend being so close, i didnt want to mess with much. I did try the pipe out a ton and got 6600rpm. Good enough for this last weekend. My son has been proving himself as is on ski. I will rejet and see what i get before it gets too cold to ride.
