750sx input on top end kits
Just picked up a 93 750sx. Is there a difference in wrist pin size. This ski looks to have a newer Teal color block. Thanks in advance.

Disreguard. I found my answer. 92-94 is the small pin 20mm and later models are 22mm big pin. Thanks.

Look at the number of mounting studs for the intake manifold. 10 studs = 20 mm or small pin. 12 studs = 22 mm or big pin. Crankcases, intake manifolds, pistons, rods, and therefore, crankshafts are NOT interchangeable.

the kawi SSXi in early years is a small pin, 750, with dual carbs, AND 12 intake mount studs.
the ONLY way to accurately tell, is measure the wrist pin size.
intake manifolds WILL interchange, you just need to remove the center 2 studs, if you have cases with 12, and want to run a 10 hole single intake.

yeah, it is pretty common....
people think dual carb = big pin, and single carb = small pin.
unfortunately, as these skis get older, have many different owners, etc, it is hard to say if anyone has made any engine changes. any more, i just recommend people to pull the cyl, and measure the piston pin.
it can be confusing. the big pin started in 1995, with the SXi. it is still a grey motor, and looks like a small pin. the 96-later are green, and are all big pin. ( even the ST 750 single carb 750)
