RidemyEVO thank you for your help. But I live in Australia.and the time difference is hard to work out. I have been told the crank is bent. But I don't know because I sent the bottom end out to be looked at.but not satisfied by the person who is doing it ($$$$)

MoCo had swithed over their manufacturing process late 88-89 and changfed from die cut blocks to a sand cast that was used for the next few years (88-91?) these motors are knowen to have bad castings and are very couse metal making them extremly dificult to punch out as the lathe chews the metal insted of shaving. The early mottors used a shovel equivilant bottom end and do not have this problem and after 91 (not sure of exact dates) they changed the composition of the metal. NEVER trust a mechanical odometer mine hasnt been hooked up for over 3yrs and the cable drives were known to break. That being said in the last 25+ yrs most of the "problem" motors would be gone or repaired. If you can do a compresion test, leak down and dip a magnet in the oil bag and you should have a good indication as to the condition of the engine. Cheers

Be careful buying a used crank. Could be too much side play in the connecting rods, bushings shot, bearing shot. DarkHorse is rebuilding mine.


It would stink to buy a used one, put it back together and have problems down the road. Previous owner had been inside my motor, replaced the crankshaft with what I'm guessing is an off the shelf used one based on the rust on it, bottomed out the pinion nut, didn't seal the cases right.

'Crank is bent' doesn't mean much, without some further explanation! Crankshaft assemblies like Harleys don't bend as such. They can go out of true, but can also be trued. I suggest you visit the person doing this and ask him to explain in words of one syllable what the problem is and to show you in what way it is 'bent'. If something is truly bent then we have a problem.....

If the crank does need to be repaired, would it not be more feasible to get a new S&S and stroke it?

I no longer have my 89 flh but had been told the cases are not made to be stroked. I also had the experience of having cylinder studs pull out of the case and had to timesert the cases. The metal is not the best on these cases.
