Noob here. Just a few simple questions

That

650sx's are great starter skis. I still keep one around as my second ski for when new people come to the lake. Their main advantage over a superjet is price...and honestly that is the only advantage IMO. IF you are strapped for cash, don't be embarrassed to pick up a nice running 650sx and ride it for a while. Most people do. I would just make sure I didn't put a single dime into with regards to mods. These are some reasons that I would buy a SJ over a 650sx.

1) Superjets are like Toyotas in regards to resale. They will hold their value more than any other ski, and any aftermarket parts you put on it will increase the value a little bit (not as much as the cost of the parts obviously). No amount of mods will increase the value of a 650sx, even though their owners think it does.
2) There are a MILLION after marked parts for SJ's. Its a little tougher to find them for 650sx's although its not impossible, which leads me to my next point.
3) You WILL outgrow either ski, and probably faster than you think. At least with the SJ you can modify it to grow with you.
4) The Kawi doesn't have a lanyard (you can mod it of course). When you fall it idles in a circle....most of the time. I had one take off on me because the throttle cable got stuck. It was a VERY bad day at the lake. SJ's have a lanyard that kills the ski when you fall.
5) I think the trays on the square noses are a little wider, although its been a while since I've been on one so it may just be my imagination. the round nose trays are definitely wider.
6) Sex appeal. The SJ has it, the 650sx doesn't.

IF I could do it all over again knowing what I know now, I would have saved another 1000 and bought a SN with a 701 in it for my first ski. If I had, it would probably still be my only ski.

thank you so much. That is huge amount of quality information. I found a good looking sx with parts added to it that I was thinking of getting but after your description I think it's best that I wait. There's a sj with a701 put into it. Is that just as good as a 701 coming in one stock ?

I'm not really the guy to ask about that. I'm not super mechanical so the other guys on here can fill you in on the difference between the two different 701's. All I know is that the dual carbs are better lol. If the guy did a good job on the swap then it should be a sweet ski. Can someone else chime in on the specifics of the 701's and what to watch for when someone swaps one in?

Yeah he put in the 61x (single carb)

701 has 2 cases and 2 cylinders.

61x case is single carb and 62t case is dual carb. The 62t has a more efficient intake track.
61x cylinder has lower port timing than the 62t cylinder. 61x makes more bottom end but can be raised if necessary. 62t make more top end without having to be ported. Most standup riders want the 61x for the more bottom end.
760 motors have nice thick cylinders for big bores but have higher port timing and thus less potential for bottom end than 701 62t/61x motors.

pre-94 superjets had the 650. 94 and 95 superjets had 61x/61x. 96-now superjets have 62t/61x. Early B1 has 61x/61x. I believe late blasters had 62t/62t. All of the other 701 couches have 61x/61x or 62t/62t. The 64U case (I believe) is the same as the 62t case, as my superjet came from the factory with a 64 designation.

OP is on a budget. Doesn't matter which motor it is. If it's clean, a 650 would do fine, because OP can always bolt something bigger and better in later.
