Working on getting my daughter a four wheeler she can ride and enjoy this upcoming summer. This is a three part video on how I took the motor apart and put it back together.

Thx for sharing I'm just in the process of rebuilding my sportsman 90. This will be very helpful

Thanks for this video! Having issue with oiler, it's dumping so much oil its locking up engine and starter not able to turn over. Gonna replace oiler n cables etc. May do a big bore kit. Appreciate you Sir!

[@garagecraze]

Thank you, If I had your problem I would just delete the oil system and mix my gas.

[@jimmyrosa2030]

great videos on this. Were you able to figure out why the new pistons and rings didn't work?

[@garagecraze]

Thank you, I know they did not work because the ring somehow got caught under the locating pin. I am guessing that I must have installed it wrong or the motor got to hot from the wrong size jet.

Isn’t the crank nut a left hand thread on the belt side?

[@garagecraze]

I just went back and checked the Raw video. This was the standard right turn thread.

[@celicablues]

Maybe i missed this in the video, so sorry in advance. Why was the stock jet not large enough?

[@garagecraze]

I am not sure why it was not large enough. I read online all over of other people having the same problem. It was a perfect fix for me. We have been riding this for over a month now with no problems.
