Can anyone measure with some calipers to two decimal points in inches (so 2.xx") the width of the rear mount on the engine that goes through the swingarm?
Thanks.
Thanks.
Engine measurement request
- Thread starter rshutchinson

We have motors ... what's a caliper .. the thing on the brakes ..
The casting is 2.33" wide .. there is a pocket on the left side about 1" dia X .140 deep
Does the left swingarm bushing go tight inside that pocket? It would seem so.
When I installed the swingarm a few days ago (though I never torqued the swingarm down so that would squeeze it all together) I measured the distance between the two bushings at 2.27" but I wasn't sure if the bushings were sitting where they would be with the stock engine installed.
So 2.33" - .14" takes me to 2.19" between the two swingarm bushings when installed, sound right?.
Thank you!
if I remember right there is a hardened steel sleeve on each side that serves as the spacer and also the inner bearing race .. it does go into the pocket .. any shimming is done out by the frame tabs
Yes, those sleeves are the bushings I am referring to. My swap doesn't utilize the swingarm pivot as a mount so I need to make a spacer to fill that void, I'm trying to find the length needed. I think it is the 2.19" measurement.
Thank you.
I think you have it right .. there's a little give in the mount tabs .. as long as the swinger with seals fits in freely with your spacer & sleeves tight .. I haven't played around with a stock swinger in so long someone else should verify this.
I just need to mimic the engine swingarm mount. I think your measurements are all I need, thank you again.
Thinking the cup that supports the chain roller might be the difference in the measurements
Well I also never torqued the swingarm down which would have squeezed it all together and closed it up some, likely down to the 2.19"
Here's a fun project to test your patience with your lathe 
.. drill a really deep .125 hole

Blasters like to rust out their swingarm bearings .. since the new sleeves where installed I used an old rusty one to show the slots that allow the greese to pass to the bearing tubes..
