One, this early 90’s Honda dirtbike has liquid cooling for some reason
Two, it has two radiators that are bridged across their tops, but not at their bottoms.
Three, if you pull the radiator hose loose on the left side to drain the coolant, the pressure from the right side radiator will cause coolant to shoot out of the coolant pump and get EVERYWHERE.
Four, other than that, this dirtbike was practically a LEGO creation. I’ve never had such an easy time un-motorcycling something. Hell, I could just pick up the engine and carry it away. The frame was so light you could practically juggle it.
There were a few issues. For one, the swingarm bolt goes THROUGH the engine, so my dream of taking the engine out and having an awesome downhill bicycle was dashed.
Secondly, part of why it was so easy to take apart was things like how said swingarm bolt could be removed by hand, because the nut wasn’t even finger-tight.

why not just machine a spacer for the length of the engine and run the botl through that?

In more detail, the bolt doesn’t actually intersect the engine, but it does go through two brackets which are attached at the back of the engine.
Fine, I think. I’ll remove the brackets.
Except the bolts for the brackets are too long to be removed with the engine still in the frame.
Hence just pulling the swingarm which, by the way, included one bolt that I’m pretty sure is welded in, because neither the air gun nor my massive breaker bar could get it loose, even after dousing it in enough penetrating oil to drown a horse.

did it have a nut on the back maybe?

To which? The bolt for the brackets was too long to pull out far enough for the engine to come loose, and the swingarm bolt did have a nut on the other side, but it didn’t matter since the damn thing wasn’t going to turn no matter what I did.
