Super Jet 90 SN 650 converted to 62t...??

[62Tom]

im sure this has been done before. i bought a 1990 650 superjet and put a 62T in it. I am still running the 650 prop and its not performing like it should (odviously)... What would be the best prop for this build? It is all stock except for wiseco pistons and a little mill work done to the head.

Call Impros

Make sure to post what impeller you end up going with. I've got a '90 impeller I'm looking to replace too.

I put a hooker 9/15 on my 91 SJ. I swapped the 650 out for a 61x 701 with head (175 PSI), factory pipe (650 chamber) and FCV. Stock single carb.
It runs damn well and pulls hard all the way. Great off the bottom, which is what I was looking for. But really its the perfect freeride setup. Way faster than a stock x2, 650sx or even newer SJ's.

If its a full 62t (cylinders), it wont have quite the bottom end punch as the 61x I hear. That might play into which prop you select. Of course depends on your application and goals.

Literally any stainless prop will be a big difference.

Cheaper option are skat 12-17 or solas 13/17 concord. A lot of people swear buy the 9/15 impros hooker but it aint cheap.

I'd be surprised if impros didn't suggest a 9/15, those props match just about any limited setup with a yami 144 pump, hard prop to beat and worth the coin
