Thanks Tiny, just so you know, this isn't my first 'Wang. I owned a 1975 model in the early 1980's and I've got a 1977 rolling chassis that I'll be installing my 1986 "Born in the USA" GL1200 engine into, once I've rebuilt it when the weather warms up, for some "Summer Wanging".
Now I must admit that I'm a 'Wang rebuild virgin, I've only had the engine outta my '75 model to replace the stator, but recently I hefted the clagged engine out of my mighty 1200 'Wang last Christmas and installed the replacement engine I imported from the US. (to bring you up to speed, I bought this bike from a wreckers for 400 bucks with a buggered engine, a result of the PO not changing the oil or filter for 10 years)
Honestly, it wasn't that hard to do the engine swap, and I did it on my own, with some help from my trusty trolley jack. The hardest part was "jiggling" the engine to allow the driveshaft back into the back of the gearbox. Not as simple as popping out the donk on a CB750, but not too difficult. Installing the exhaust was a snack with the mufflers off, they have a special composite seal between the muffler and header pipe and both of mine were missing, so the mufflers just fell off. The hardest thing was removing all of the old muffler putty, RTV sealant and exhaust bandage goop that the PO had used rather than spending 20 bucks on new seals. Go figure........
Now I've got the "Ride off" stand fitted, I can (and have) removed the complete exhaust system, as there's no centre stand to get in the way. I'm looking forward to rebuilding my spare 1200 engine when the weather warms up again, I reckon a 1200 engine in a GL1000 rolling chassis will kick a Z1's butt! (not that Z1 pilots like to race their bikes, they're all "trailer sailors" nowadays, and don't want to lower their resale value by getting them dirty.........
