Accent timing cam question

Post by smokin »

Hi All, installed the accent ignition on my Gt750 haven't started it yet something doesn't seem right with the timing cam, my cam has 4 holes when I set it for the center cylinder it looks to fire on the first timing hole and on the left cylinder it looks like it fires on the second timing hole and on the right cylinder when it's suppose to fire there is no hole. So the firing sequence is left cylinder second cam hole, center cylinder first cam hole, right cylinder no timing hole is this the way your timing cams are setup? I know the cams have magnets in them and my cam seem to be setup for two cylinders, what do you think are yours setup this way or they sent me the wrong cam?

Kick it over and you will see three sparks, Don't have any idea how those electrons work out where to go and when to go there, but the rotor is the same as mine and seems to work. Of course I have not run the thing yet, but it does seem to spark at the right time.

I don't know the accent system so this is more general observations, but it's often the trailing edge rather than the leading edge that triggers the ignition so it could be just as the holes finishes passing the sensor. Also electronic ignition tend to trigger - wait - spark be it to make space for an electronic advance curve, or dwell in a tci system to build the field in the coil, or charge the capacitor in a cdi.

The directo relationship between Tigger and spark of points system is absent in electronic systems.

If there is only one sensor it needs to figure out which hole relates to which cylinder so it needs some asymmetrical feature to detect this.

Got it running today, the timing cam seems to throw you off with the extra holes but I guess that's the way they had to make it. The instructions on timing are off, it said the led light should go out when the center timing mark lines up with the timing mark, the led light doesn't go off until way pass the timing mark, so I lined the led light and the center timing mark to go on when they meet at the timing mark. Runs fine now no more points !

Hello, How do you order the Accent ignition? I tried his kontakt link but there is an error when I hit abschicken(send)?

I have just fitted an Accent ignition. Had no problems fitting it using the center pot with a dial gauge and timing the ignition so the that led comes on at the correct BTDC center pot position, as my instructions state.

However, when I come to check it with a strobe I find that the timing mark image is juddering making it difficult to confirm that the correct timing has been set. This is the same on all three pots and irrespective of whether I use the bikes battery or a separate battery on the strobe. I also find that when using the center pot that the LH timing mark is superimposed on the Center timing mark, so are they both firing at the same time? Have run the bike and it seems OK but concerned about the strobe readings as I had stable readings with the CB's fitted and on checking other bikes on which I fitted electronic ignition using the same strobe?

Have you checked yours with a strobe and how have you found it?

Have tried to contact Uwe but he is on holiday until 8th Aug.

Uwe is on holiday until 8th Aug, so you will not get any response until then. Try uwe.gottwald@accent-electronic.com

Has anybody who has fitted the Accent ignition had any of the above problems when checking/setting the timing with a strobe?

I set mine to the center timing mark and was using the electric starter and it seamed to run alright, but recently my battery went bad and I had to kick start it which on a couple of times it kicked back on me and started to run backwards. I checked the timing with a dial gauge and it was a little off so I retarded it, it hasn't kicked back on me and still running fine, haven't used a timing light on it yet I'll have to fine someone who has one in order to see how the other cylinders line up.
