Anybody know if a twin 650 will fit in a Trident frame? Without a bunch of cutting of course...

Don't know anyone that has done it, as they are uglier that the average 60's twin frame, but the 71-on oil in frame design was a Rob North design for the trident engine. I have seen a couple of the OIF frames with Trident engines, so I'm presuming the reverse would be similarly simple.
