Thanks guys, it's true, K7/8 and F's are not my favourites, but that F2 (a US import) is pretty complete, was cheap, and will be a good flip. The big selling point for me is that the tank isn't full of rust or bondo, good F tanks are hard to come by. When I was in Canberra I bought a near complete F2 engine that the PO, an engineer, had cleaned up beautifully, including reconditioning the head with new valves, guides and springs, and had it skimmed.
Sadly he also had it bored for some Dunstall 811cc pistons, but lost them, but that's OK, I'll pop the sleeves out and throw in a good used 836cc kit I happen to have in one of my piles. The box of take off's that Cliff gave me will come in handy, and all I've had to order so far is a new seat cover from Britain.
The engine in this one is locked, as it's been sitting in a barn since 2010, so I'll try the ATF and Acetone trick just to see if it's a goer, but if not that's unimportant with what I have already to go, so if no good it'll get yanked, I'll clean up the rust, rattle can whatever needs painting, throw on some new stinko's, and take it for a lap. All going well, it'll be a nice Christmas present for someone, but if not, it won't be the ugliest Honda in my garage, my CX500 still has that honour!
