SX/SXi/SXi Pro SBT engine question

[SP33]

I might order an engine from SBT for my 750 SXI Big Pin. SBT wants me to measure the threads for my PTO. There is an option for 18mm and 20mm. I measured the threads for the PTO and I got 19.5mm. Anyone know which one I should order?

Ima guess 20mm.

 

[SP33]

That was my guess too.

750 should be 20mm

most 650s are 18mm but some of the newer motors pto went to 20mm


i have a small pin short block for sale for $400 if interested

has 160/160 psi compression....i have new seals/gaskets for motor as well

 

[stagesrt4]

its $400 for short block

if you would like any parts listed bellow its extra
-flywheel
-starter
-bendix
-oil block off
-crank case block off
-etc...

You need to buy my ported motor with the after market
Head. Also my sxr dry pipe might just work.. a lot more power

Ran into this problem before and ended up sending it back to SBT. The 750 came with either 18mm or a 20. You have a 20mm which is most common.
