Hey guys I just picked up a 1990 sj all stock with the 650 of course. I have a 1994 raider that used to be what I rode all the time but now I want that 701 in my superjet. Any suggestions on if its a good idea and will my raider be a slug with the 650? The way I look at it is id much rather have that power in my sj. Its a purple hull raider so the 650 may not be horrible. Thanks for the advice fellas!
