Did timing advance, did I mess up?

[xunedeinx]

Allright, so I followed the steps in the wiki to the T, no issues...

It feels like it wants to stay revved now, Like it dont come back down as fast, I bounced off redline for the first time because when I shifted I didnt expect it to stay high as long, and I usually revmatch while shifting, and the idle is at 2k instead of 1800ish, which is annoying (I know how to fix).

Also, power seems to be about the same, but the bike is a little warmer. If anything, I may have slightly more torque down below, but the top end feels a little lacking...

Now, It could be because I been cooped inside for 3 days bc of rain, and im being overly sensitive, or is it because I did it wrong?

Advancing the ignition will cause the bike to produce more power, so it's possible that if something else is out of adjustment (leaking intake boot, clogged carb with too high an idle) the adjustment would cause your idle to start hanging when it wasn't as much of an issue as before.

If you're doing the modification by hand, I'd advise you to throw a degree wheel on the rotor and check exactly how far you actually advanced things. Model of the bike makes a difference too - the most I'd advance a 49 state model is ~5 degrees. But the CA bikes are pretty far retarded, so you can move those a lot further forward.

Also, I'd strongly advise you to combine the ignition advance with a carb rejet. Pushing the ignition timing forward is going to exacerbate any existing lean condition - I reverted to factory timing after I saw how white my plugs looked on the stock jetting.

I am interested how this will turn out. I remember reading here on forums that ignition advancing can not be done to newer GS500s... 
at least not by following the guide for older models.

can you clarify that confusion?

I was told by a Suzuki dealer mechanic that the ignition timing is controlled by an outside box and that adding and advanced rotor or plate would make no difference or at most cause running issues.He went on to say that is the reason for the single crankshaft ignition trigger and throttle position sensor.In all honesty,I can't confirm this.The newest bike I have worked on is a 49 state legal 2002 GS500E.I thought I would throw that out there and see if anyone can confirm.I know buttha thinks all of the new gadgetry is for nothing.

If I'm not mistaken, the ignition box translates the signal from the end of the rotor to the spark from the coil. Except it adds the advance as the rpm's get higher. So advancing the signal on the rotor a couple degrees would add that advance to higher rpm's too. Can't speak for the TPS on newer carbs though.

Does that make sense?

so, in the end, is it advanced, is it over-ridden by the ecu ( I didnt even think carborated bikes had an ecu), or its it helping the ecu?

It looks like any ordinary distributer from a car that ive ever seen, and twisting the cover would be the same as rotating that plate...so where exactly would the ecu be butting in?

Anyone around that wanna go on a road trip to tell me if it did anything?

There will be beer!

there is definitively no distributor on a GS... Distributors control spark through a single coil and distribute it using some sort of point system... GS's have Coil On Plug, all that is inside the engine cover is the crank position sensor, clocking the sensor should work on all bikes because it introduces a static change of X degrees, now if on the newer GS's the plate is not used the same way and theres a different pickup thats where the difference will come into play.

[xunedeinx]

Oh, so then why all the points on it? it looks like a dizzy a little.

An ECU is only capable of compensating for changes it can detect. Unless the newer generation GS500s have some sort of secondary crankshaft or camshaft timing sensor (they don't) it would be impossible for the ECU to compensate for timing adjustments made at the pickup.
