Jetting time

[rd400canuck]

Hi Alain,

The first time I did it I used a little bulb that would come on when the points closed as I rotated the crank with a wrench. I set the adjustable pointer  to point to the notch at 1.8mm then adjusted points until the bulb would turn on when the pointer and notch were aligned.

things is... after I do that.... then start the motor and use the timing gun to check.... the notch is showing up after the pointer by a decent amount.

this is exactly why you use a dynamic timing light. glad you found it

I understand the process you used (which could explain the error), but I think you meant to say when the bulb would turn off (when the point opens).

Now put that bad boy at 2.0mm and enjoy!

Two things that I can think of.

When you change direction on the crank there is a bit play that you will need to take up by going past your ending firing point then going regular direction to set your ignition. Watch Mark's awesome vid https://m.youtube.com/watch?v=Iqardto3Kbs&t=186s

Also I think that the HPI is advancing a bit at idle so maybe you need to up a bit on your jets.
