I have been seeing some posts about converting a Raptor to use a Zenoah gas engine.
Before I take a leap, can some one measure the start shaft bearing block (or the main shaft bearing block) width.
I'm thinking of using a Predator clutch/fan/spur gear assembly on the Zenoah.
A guy in Sweden has fit a zenoah into the bottom frames of a Raptor 60. He is using a old Kalt fan and clutch which are not available here.

Ps can you also measure the raptor fan outside diameter?
thanks.

The starter, clutch, pinion bearing block is 32mm wide. I just happened to have mine out of my 60. I was replacing a bearing and upgrading to PV0323 90 3D clutch. Doing the upgrade before I shove a YS .91 up there.

Don't come off the throttle untill you see your GOD!
