Running the engine out of the bike..thoughts?

I pulled the motor a few weeks ago and I'm just getting started fixing the issues it's had from last season. One thing I noticed last time I worked on it was I always had a problem with SOMETHING after I put it back in the frame and had to pull it again, obviously this is a huge headache and hassle. What do I need to consider when running the engine out of the bike?
  1. Fuel is obvious, I plan to rig up a small fuel tank right on top the carbs
  2. Electrical.. need battery, starter, coils, sensors, tach, what else?
  3. Clutch and shifter
  4. Throttle cable hooked to carbs, so I'm not getting my hands burnt moving the lever
  5. Choke hooked to carbs as well

Exhaust is probably necessary, but not sure how I could rig that up since it gets so hot. The engine itself will be on my workbench, sitting on top of some concrete pavers so it doesn't burn the wood surface it's on. Do I need to strap it down? It's hard to tell how much it can move in the bike itself, doesn't seem like a lot.

Is this a horrible idea?

your gonna need the igniter and its wiring (which goes thru the harness, along with MOST of the wiring you already listed). yea, you can rig up something, but the engine isnt that 'self contained'.

cooling.. some way to supply coolant and radiator of some sort, unless only gonna run it for a few seconds

clutch/shifter.. not really needed.. you not gonna hook up a driveshaft and rear wheel are ya? just need a way to satisfy any nanny switchs that may be in the system (unless they are totally bypassed by your setup)

I would secure it somehow to the bench.. it will be rocking/rolling to a degree.. dont want it to fall off and land on the floor

It's not a horrible idea....its just not a good idea.
Figure how much stuff you'll have to rig up, and how long that takes.....then how long it will take to undo all of that----------compared to how long it takes to just put the engine in the frame.

Given its a water cooled motor which adds some problems, and the difficulty of wiring up the coils, and other electrics, I'd say you should be able to install the motor in the frame a lot faster than trying to get it to run by not.....

I agree KM, the payoff isnt worth the work in this case.

there are cases in which it would be worth it.. but them situations have much less to 'rig up' to get the engine to run
