    I'm ok with stretching the springs, it wasn't much I just wanted to do it a little at a time to not over do it.

    .....


    .....

    And now, as the late great Tom Petty said...




    The waiting is the hardest part.




    Hope my parts come back soon, I'm anxious to hear this motor run again. Should just be another week or two.

    Well, I heard from Crankworks today and their large press has been down for parts and I'm still in waiting. I couldn't get any one to tell me a time frame, other than two weeks to a month "hopefully", before they even tear down and inspect. I shipped it out late September. Has anyone else dealt with them lately? I don't want to slag them and I'm not, but just curious if their backlog is typical (of similar shops).

    Got some good news, the cylinders are done and MT is shipping them back. They're on the way and should arrive early next week. Can't do much till the crank gets back though.

    Good to hear and glad that they took the time to call you with an update. I'm sure they are slammed and probably have a back-log of work they are buried in, in that scenario it's easy to have communication fall to the wayside.
    Be sure to get measurements of your cylinders when they arrive, any local shop should be able to do it in a few min (if you don't have a good ski shop, go to a bike shop that works on 2-strokes). Yama pistons for the gpr come in various sizes (a,b,c,d) and they need to be matched accordingly with your jugs to be within clearance specs (found in the service manual). Pro-x pistons are my choice and easily ordered by size.
    Enjoy the build!

    Millennium is shipping me all new pro x pistons with my rebuilt nikasil replated cylinders,, matched and with ring gaps filed and fit. One step ahead already. I'm getting excited like I used to back in my racing day when I had this ski running hot.

    Alright, the cylinders came in with the pistons, rings and wrist pins. I need recommendations for wrist pin bearings. Anyone have some input on wrist bearings? Mfg, source, type etc...?
