" Its nothing crazy. "
____ Even if so, I could still possibly become drawn-onboard.
" I am trying to save 61' 125 sport that needs new crank, bearings, charging system, clutch assembly and timing gears and oil pump.. "
____ What makes you sure that it needs replacement crankshaft ?
" correct me if im wrong but they should work for a proper 125, right? "
____ I'd figure so but, I've only ever merely seen only-just ONE 125-OHC.Sport model, and have never worked-on any OHC.125-models,, so can't confirm for-sure.
" Would like to hear your thoughts on this one Bob.
if you have a soft spot for 125 Sports. "
____ I do indeed like the 125-Sport (lots-more than the Monza-Jr), however there's more than one reason for why it's likely I won't be a source of a 160 bottom-end for you...
My 160 bottom-end is complete & all-together, so it's not sensible to part-it-out,, and besides, I have TWO 160 top-ends for completing the 160-motor,, and-also, I believe I recall that the motor's top-end was taken-off to discover that the con-rod was loose. _ So the crankshaft likely wouldn't be of any more use to you than the crank you have.
____ It seems to me that ya can find such 160-parts listed on eBay & eBid fairly often enough anyhow. _ For example:
http://www.ebay.com/itm/1960s-Ducati-Mo ... a7&vxp=mtr . _ With that motor, you could probably get your Sport road-going considerably sooner. _ (If the seller were to instead part-out that 160-motor, he'd then much-likely get more than just 200-bucks, [although take considerably longer to do so] !)
Have you not been keeping a watch-out for such parts-listings ?
__ Also, I (or someone-else here) could probably relatively easily come-up with most-all of the other parts you're looking for.
Hopeful-Cheers,
