Did you kiss the seller when you f***** them? $1K is a steal for the motor! Give me the VIN (left case stamping) and the small numbers stamped on the top of the carburetor body ("M-??"), and we'll go from there. Is the motor bolted down in the frame? Should be 3/8" spacer under the front motor mount - very important!
Sounds tooo good..Did you get a title with this?..Does this late model swingarm frame still have its neck numbers? And while you are checking the motor VIN, peek at the belly production numbers down by your skid guard. If the front fork is late model, it will have a number on the lower tree also on the lock tab. Let's hope none are missing or altered.
Smells like someone died around here.. its been at least 30 years since i saw a knuckle motor in a frame of any sort go for a grand. Thats kinda the equivalent of HD's in 1970 We must have stumbled onto someone seriously uninformed or desparate or nefarious.
" That far back" really is no retrograde movement. With all that FHP and others have done, you can have a bike that will not only be the best example of Harleys work, it can also be the fastest. With the monetary head start that you have, the sky should be the limit for a resto or a custom. Keep the faith man, all that new stuff may be shiny, but it is like a big leg, woman its got no soul. Not to mention they don't look as good and don't go as fast.Knuckleheads forever!
Your mis-matched cases are no problem, and neither is your VIN unless it matches the production number (they never did, and nearly always were lower than the belly number.) Your swingarm frame would seem to be a pre-70 model also, which is great! Perhaps you made the purchase of the millenium, as I would appraise a basket '40 OHV motor at over three times what you paid for the whole bike, particularly with the desireable M-5 Linkert. I suggest you locate someone with experience to look all of your hardware over, and then look forward to the adventure of putting your own touch on her!
Bastard bikes are best! I found that swingarm chassis are a little heavy for 61 inchers, but I love my '37 NeglectaGlide anyway. (How do I properly post a j-peg here?) Look far and wide for a licensed shop that will take the time to personally look over your paperwork as well as your mechanical needs.
