Title: 1967 Yamaha YM2 Rebuild
Post by: edv2009 on April 11, 2018, 05:17:45 AM
I just picked up a 67 YM2. Itís been parked for 30 years! Just going thru everything that needs to be done, and first up on the agenda is there is no spark. Has anyone changed the points over to CDI? It is even wise?

Stick with the points until you get it running. Have a good charge in the battery?

Just had a look in my big Chiltons ...there must be a million different models,pages of specs& WHY.....anyhoo,its always a good idea to replace capacitors ,as they fail first of any ignition components.....About that time the US legislated to prevent street bikes being stripped of electrics for offroad riding,this required complicated wiring and ignition systems that are hard for a british bike owner to figure out.
