    Jack shaft removal. Need help

    Ya I thought of that while I was giving it some love taps. If I can get it back out I will have to give it a shot i thought it should be a somewhat of a loose fit with that sleeve and nut. I don’t want to take that nut off in case that sleeve expands and I can’t get it to start again

    2022 anyone?bueller bueller

    2022 anyone?bueller bueller

    I wish yamaha would get with the times and offer some more options. Or atleast put some r&d into something. I am a true blue fan but look at the options you get from Polaris and ski doo like luggage compartments, the odd shock option, colours, dash/gauge package. Look at the Polaris hand...

    Winder cuts out

Then took the sensors out and put them by the heat in a way I thought could drain any water out over night. Put it back together and has been...

    Primary Rollers

    I know it’s an old thread but. Has anyone found a fix for these rollers yet? I tried the ones with krylon bushings or what ever It’s called, And just checking the sled over and the rollers are toast with about 300 miles on them. Maybe I should be looking deeper at something?

    Winder cuts out

    I’m not sure if it fixed mine or it was a coincidence. But I took all the lines off the sensors below the fuse box. Let them hang down over night(don’t forget where the go). Took the sensors out blew them out with my mouth and since I was that far I took the inter cooler out and set it so it...
