Re: Knuckle frame

A Pan engine won't fit in a Knuck frame without serious modification.

Re: Knuckle frame

I'll take some more tomorrow, the seat tube is bashed in to clear the rear head though.

To be done correctly, if there is such a way to goober a frame, the front motor mount need to be lowered. The Panhead front mount is lower than the Knuck and the mounts won't sit flush of the frame unless the front mount is lowered.

Re: Knuckle frame

Jerry,
If you will notice this is a brazed frame. Brazed frames came in during 1944.

Re: Knuckle frame

Notice how the front of your front motor mounts are raised off the frame? They are incorrectly sitting on the mounts and will eventually break them.

Re: Knuckle frame

Is that because it's a pan motor?

Re: Knuckle frame

The front motor mount on a Pan is lower than a Knuck. So when you stuff a Pan Motor into a Knuck frame the mounts don't sit flush.
