Title: CDI question
Post by: sdxp787 on October 14, 2014, 07:20:02 AM

I have an 86 motor.  I recently purchased an 87 cylinder (295cc).  I know I need to switch cranks to match the 87 cylinder from the 86.  Question is about the electronics.  I have heard the 86 CDI has different timing curves than the 87-89.  will I need to switch to the 87 CDI also?

All 4 years timing curves are very similar and the changes ever so slight. You will not notice any change.
