    Who's going to do your cylinders??? They can get your pistons. You can get them from DASA (Dan Lamey), Group K, Lowell Horning, TJ, just to name a few. Waterdawg customs also sells them.

    Lamey's shop uses Kawasaki KX500 pistons with the pins resized. I have one of these motors and have had no issues with the resized pins. The pistons can be bought from Wiseco direct if you want someone else to resize the pins.

    P.S. If you need any input or help with your BB project let me know, I've got two up and running.

    I haven't had the same experience with my Lamey motor. Hopatconggpr, do you still have a line on 90mm pistons? That will be my next build. Maybe with a stroked crank to go with the 90mm slugs. Gotta get me another set of cases.....
