    Need Help with troubleshoting

    I need help from someone who has been wrenching longer then me...

    Bought the Ultra 250x in May and it ran great all summer. After labor day it sat for about 3 weeks and when i started it back up it idled rough, stalled and only got to about 40 mph. I took it in for service and they said 2 plugs were bad - it only had 20 hours on it at this point - does this make sense??

    So after the plugs were replaced I took it for a spin yesterday and while the idle was better it still only hit about 40 mph. While I was riding at 40 mph the engine/supercharger seemed to finally kick in, acceleration was back and top end to about 65 mph - then it would sputter/slip and go back down to 40 mph after about 10 minutes. I shut it down then started back up and it seemed to run fine again.

    Does this sound like a problem with the supercharger tensioner, plugs?

    Thanks for any help...

    my heart goes out to you.. pull the seals off those bearings and rinse them real good, then replace the seals. after that you will only have one more time
