348 Ignition Timing


Recommended Posts



You use that gauge to find TDC, then make a TDC mark on the flywheel in line with something on the casing. Then measure from the mark to the position you want the points to open (either using a degree wheel, or by using geometry and measuring around the circumference) and make a timing mark. You then only have to be looking at the timing mark on the flywheel instead of having to read that tiny scale on the TDC tool

If you want to check that your timing is right after setting it, you can use a strobe type timing light on your timing mark. Its a bit of a pain with the 348 though because it means either bump-starting the motor, or taking the flywheel cover off after kickstarting it.

Thanks, feetup.

I had my stator repaired by Steve at Bradford Ignitions, and followed your guide for re-timing. The bike's now starting and running well, so I'm back in business.

Interestingly, the timing had been set pretty well advanced at maybe 2.2 - 2.6mm BTDC, so it'll be good to see how the bike feels and rides now.

Thanks again all.
