Crank Case Repair. in Other troubleshooting Posted March 9 1 hour ago, NE0 said: Hi scott, have you thought about replacing the crankcases,? might be a cheaper option. Theres a pair of crankcases on ebay for a DT125MX which are identical. I know they are in Greece but even with customs it would be cheaper. https://www.ebay.co.uk/itm/Yamaha-dt125-dt-125-mx-1978-2A600-engine-casings-cases-motor/124306021524?hash=item1cf1375c94:g:R-AAAOSwH2Be3CHk There was a thread a few years ago about the 125MX crankcase, and Airhead confirmed they are identical. Might be worth thinking about? Thanks for the reply Neo, unfortunately this is the case with the engine number on and with the frame it's out of it's numbers matching. I really want to try and save it.
