The two banjo bolts are different, and honestly I don't think I'd swap them around if it were my bike.
The banjo bolt at the oil pump output is Honda p/n 15542-358-000. It looks like an M6x20 shoulder bolt, with the center drilled out & another hole at a right angle in the shoulder section. 7 or 8 of these are available NOS on eBay right now.
The banjo bolt at the intake manifold is Honda p/n 15543-358-000. I believe this is nearly identical to the one above, except it has a short rounded 'nose' section after the threads that pokes into the air stream inside the manifold. This one's harder to find, at least right now.
I think these pumps put out too much oil when new, and just got worse with age & internal wear. Vintage injector oils were also lower-tech and may have been designed to burn rather than stick around, thus allowing more oil to be used without fouling. You can turn the pump cable adjuster down all the way without worry; it will put out the same oil at idle/low throttle and less at mid/high throttle, still too much though.
Be sure to run the bike at full throttle for at least three 20-second bursts, to clear out at least some of the massive crankcase oil buildup the bike almost certainly has (and if it doesn't, the full-throttle runs aren't going to hurt anything).
We put an NGK BP7ES plug in my friend's MT250 recently, it definitely worked better w/less misfiring than the stock B8ES. A BP7EVX would be even better.
