650 superjet: How can I get some more power?

[Coreyf983]

I just picked up a SN SJ and it has quite of bit of work done to it. The engine is left alone though, and it runs great, but is a total dog compared to my last ski (sxi pro with sxr engine). I plan to drop a 701 in it this winter or sometime in the next year, but my question is:

What can I do to help this thing get a bit more power?

This is my first yamaha, so is this a wetpipe? can I "dry" it out a bit to get some higher rpms? Any ideas for cheap is much appreciated. Timing advance and such? thanks guys.

How much money do you have to spend at the moment?

You can buy a 701 B pipe and use it on your 650 until you drop in the 701.

Advance the timing and get a pipe of any sorts. Anything is going to be better than that pipe that is on there. PM mouthfulloflake I think he was running a bunch of timing on a 650 motor with good results. If it doesn't have an MSD enhancer and stock head (150 PSI compression) I personally would max the timing out and limit my WOT to the 2 to 3 second range. And bore the nozzle which would give you more low end punch.

I know all about how to add aftermarket parts like pipes and such, but I was just wondering if there is anything I can do RIGHT NOW while im waiting to buy add ons. Timing advance seems like a good idea. Im gunna check the compression to see if I can maybe boost that up a bit.

Motor wise, i dont know. You can re prop it for a gain in performance.
