SX/SXi/SXi Pro 750sx question

[u887266]

I have a 95 750sx and I have put a coffeman pipe, pro-x pistons .50mm over, timing advance, 46mm blackjack, and pjs intake. My question is that the ski just doesn't have the take off pop like my 650sx does. Is this typical or do I need to do some more tunning on my carb. In kinda addvice will be help full.

How about a aftermarket impeller? The skat-trak swirl is good.

x2 put a swirl impeller on there and maybe keep playing with the carb. I run a 8/16 big hub swirl on mine but still am looking for bottom. But difinatly a huge improvement over stock!!! Probably my Favorite mod i have done

Right now I have a 12/19 swirl if I remember right.

Play with your jetting. Once you get that 46 close, you'll know!

How much are some of yall shaving off your heads. I was thinking .010, but im not sure if that will be too much.
