If i remember right the nozzle bore is bigger on a 650 than a 750 correct? and are the pump wedges the same for the 750 and 650 pumps?

Looking for another cheap bolt on mod for bottom end.

Tad bigger but not much. X2 is the largest.

The 650 is 84mm and the 750 is 76mm. I'm running the 650 compression nozzle on a 750/800 pump with a 15/24* prop, it works very well. The wedge will fit both also.

(hmm maybe Im thinking wrong and theres not much difference between x2 and 650... i forget now)

750 are 78-80mm depending on year! i got a stock 80mm, straight bore 84.5mm and a taper bore 84mm if your looking for one! or you can send it to #zero on X-h2o and he will bore it to whatever you want it to for like $45!

Yes, 8mm difference. I remeasured the three 750 and one 800 that I have and they are all 76mm. The two 650 that I have are 83-1/2 to 84mm, the plastic nozzle is not very round and the flat spots are 78mm.

the 750SX is an 80mm, and that oem setup was with a wedge. the SXis were 76mm as well as the SXR all years. The 650SX and I believe the X2 nozzles were all 84mm

does that 4mm really make that much of a difference with already having a stubby freestyle cone?

Only if your motor can spin your prop fast enough to create enough pressure to make a difference.
