I'm looking for proper mag removal tool for 1964 yds3!Also trying to find crankcase seals. My problem seems to be lack of vacuum and believe it to be air leak probably on R/H side or dry side. It has very high idle.
Welcome. Do you have a picture of the piece you want to remove? I rebuilt a YDS5 with the starter/generator on right hand side and used an 8mm bolt and slide hammer to get the rotor off. Pics would help. My build thread. https://2fiftycc.com/index.php?threads/1967-yamaha-ds-5-250cc-rebuild.2185/
There's a few NOS seal's on ebay for them http://www.ebay.com/sch/i.html?_odk...+seal.TRS0&_nkw=yds3+crank+case+seal&_sacat=0
I removed rotor OK now looking for yds3 armature removal tool! Might have to make it and use a slide hammer! Thanks for info.
Stumbled upon my biggest problem, oil injection line removed and nothing plugging up intake, resulting in large vacuum loss!
Yes I have a wiring diagram though my bike that I wired dosent exactly follow it! I found a brn wire in headlamp that interupts ignition and put my kill switch in between it! Thanks,Vic
