  1. Good day. No mud very little dust only lost one tire ripped the side wall on something. The morning was cold but ok. I have to agree with ZillaFreak the place is rough, rocks and more rocks. One of the guys had a Polaris with an odometer we rode 47 miles.

  2. Pulled it apart. Put the crank in a lathe between centers and checked with a dial indacator it is way out of spec for run out as much as .010 the most it can be is .002. Everthing else checks good over all and the width of the webs and rod side play. So could I have done it pressing new bearings on or maybe it got dropped at the shop. It is welded do you have to remove the weld to true it again or is it junk.

    I had another crank that was not welded put it in and torqued every thing it spins free. I need to put new bearings on it I guess Ill freeze it and heat the bearings instead of the press?

  3. Took it apart cleaned everthing up again (I hate yamabond) put it back togather it is harder to turn now than it was. I had the crank trued and welded. But i put the new bearings on myself with a press so I'm thinking the crank may not be true. I'm going to take it apart tomorrow and check the crank run out. That's the only thing that makes any since to me it move but gets tighter.

  4. Rebuilding a stock motor. Cranks checked out ok per the manual. Put new bearings and seals on the crank, it turned easy sitting in the case half. Put the sealer on the cases put the other half on and torqued the bolt per the manual. The crank seems to turn hard. I have not put the fly wheel on, if I grab the end of the crank I can not turn it. On the other side with the gears I put a socket on the nut I can turn it by hand( without a ratchet) it just seems real tight. I lubed the seals and the bearing. This not my first motor but seems to turn harder than the others.banghead.gif

    Sounds wild, I'm just looking for a stock motor that is running or needing rebuilt.

  6. Got the frame. Need a motor. Someone has to have one or know someone that does.

     

     

    I sold my 500. I could not refuse the offer a the kid had to have it. Now I'm going to build a AF500. Going to pickup the frame tomorrow. I need an engine would like to have 90 or newer but will not be picky. May even just buy parts and put one togather let me know what you have or if you know someone that has one.
