7-8MM 400ex Stroker

[Boone-ATV]

Hey guys, been awya for site for awhile but looking for any new info. I have had several built 400's: 416, 440.460 stroker etc in the past. Does any company still make any cranks with 6-8MM stroker? Thanks for any help-Mike Boone

The only downfall to a 7mm stroker crank is the machining work required to make it fit. The counterbalancer needs machined, and the transmission counter shaft needs work as well IIRC.
