    443 Puma - Dune Motor Build

    This build thread is a bit overdue.

    Been toying with the idea of building a big Puma for the dunes over the last couple of years. No donor bottom end was supplied so the majority of bottom end parts are NOS or OEM take-outs - definitely NOT a cost effective way to build a motor!


    Started with a set of OEM ATC cases (complete with VIN stickers), courtesy of @Redred55:



    Puma top end shows up @ Hybrid Engineering:



    Had Crank Works build me a +6mm from OEM halves. Now for the crank porn:





    Making progress:



    Assembly begins:

    Looks great when you start. Be sure to get lots of pics after assembly. The bottom end polish will only last so long, so savor it while its still shiny.

    I saw that crank at Pete's, when I dropped off my motor last month. Pretty impressive workmanship, with all the heavy metal they added and that massively reworked rod.

    No override. 2 different Puma's. This motor is going in my dune bike. The LSR hillshooter already has a Puma in it.

    Yes it really is gorgeous. I took it to Crank Works personally with I was in AZ and checked on it a handful of times to make sure it was exactly as desired. There was a ton of work involved on their end and the $1300 bill reflected that!

    sweet project. hopefully the crank doesnt give you any trouble with the lower pin being moved so high on the webs
    to much power is almost enough

    thats good. hopefully it stays that way. when you thin out the material above the pin it can get alittle sketchy
