Timing

[biggdann]

I have an 04 883 and i'm looking to convert to a 1200 soon. Whats the prcedure for setting the timing? Ilooked in the manual and it doesn't say how. Thanks, Dan

Not adjustable ... The timing curve is embedded in the Ign. Control Module.

That's why your manual doesn't address it.

Thanks Turbota. I did read that, but I wasn't sure if that meant it couldn't be adjusted. So, does that mean i have to go to an adjustable ignition when i do my conversion in order to set the proper timing? Or does it set itself by using the info from the MAP and CKP sensors like it does now?

Just because you are planning a conversion, don't mean you need to change timing. From everything I have heard, the stock timing in these bikes is really pretty good.

What you will need more than timing curve changes is a change in the rev limiter if you plan on larger cams with the conversion. In my case, my stock rev limiter is set to approx 5,800 rpm on my 04 1200R. I replaced the cams with a set of SE cams. These cams will make power all the way up to about 6,700 revs ... So, I used the SE Ignition module that has a 7,000 rev limiter. It also retards timing 5 degrees at wide open throttle (WOT). Supposidly to limit detonation in higher compression engines while operating at high revs.

You have an 883. I don't know if the SE module will work with it or not (might check the SE catalog).

There are some adjustable ignitions made by the aftermarket, but I don't have any first hand info on them. Just because you are increasing the displacement on your 883, I can't really see that you now would need to change the ignition curve. The stock curve really is very good and won't cost you any HP or torque.

Again, if you need a higher rev limiter ... That's another story, and you will then need a different module. These modules are not adjustable at all, and there is nothing you can do with the MAP or crank sensor to change anything.

Good luck,
Ron
