We had Greame's beautiful Honda XR75 back in recently to replace the carby, as the old one has some issues, as well as ditch the original points system, and fit up a HPI electronic ignition system.
As this kit is somewhat universal, it was up to us to get some baselines from the original system, and make sure the new system was timed correctly. For this we used a dial gauge down the spark plug hole, and made sure we had everything spot on.
Advance starts at 2000 rpm, and then double checking it reaches maximum advance at the correct RPM. With the new flywheel only using the taper, and no key way meant if you didn't know what you were doing, you could get it very wrong.
Easy starting, strong reliable spark and no maintenance means this upgrade is a no brainer.
