    Svho wont go over 30mph - 12 hours on it... Help!!!!

    I just bought this damn thing and it only has 12 hrs on it.
    Won't go over 30mph.

    Nothing in impeller.
    Not on L Mode
    Dealership has no clue.

    Any one have a can of gas and a match I can borrow?

    my guess will be , its not producing boost. take it to another dealer and make sure to include this dealer in a no no list. lol.
    take the intake boot off and try to spend the s/c wheel , it supposed to go only one way and lock the other way. if it spend both ways or it doesn't spend at all , it has a bad clutch.

    I read you said it's not in learn mode but... That's all mine runs in "L" mode. Try changing modes for S&Gs.

    I'm in Vancouver Canada and they need to fly in a Yamaha specialist b/c the new SVHO has a new computer system that only he knows how to use.
    He's on vacation for another week and it's been in there for 2 weeks now.

    They've checked it over with a fine tooth comb and water test it. No luck.

    I was going 50mph no prob, I stopped and I was trying to change the speedo to RPMS with the two buttons and then I accelerated and it's not wanting to go at all.

    Kill me!!!!

    Here's another kick in the balls. My 08 FX SHO has a blown engine and it's being shipped to SBT in Florida and I haven't had it since May - If I had hair I'd pull it out.

    All of this happened at 11hrs and I drove it home for the next 1hr so we are now at 12hrs.
    But at 4hrs I was out riding and the dash lit up like a Christmas tree and machine didn't feel right.
    I quickly went to shore and had a beer and then went to try it again and it was fine.

    I'm thinking LEMON !!!

    seriously need to check the hose from the intercooler and the throttle body, these are known to be loose from the factory, i can loosen the clamp with a 7mm scoket with my fingers, i would also try disconnectiong the battery for 3-5 mins and then try again, something went afoul when you were fucking with the dash button. what RPM does it max out at ???
