For a significantly milder engine, 8 initial is fine, 12 vacuum will give 20 IDLE degrees. With any 400, 32 degrees total mechanical and initial advance would work well, the longer stroke fo the 400 doesn't like, nor need more total degrees. Examples of total degrees, 12 initial + 20 mechanical = 32, 8 initial + 24 mechanical = 32.

Ignition timing is quite simple and the benefits to be gained are great... namely more power, longer engine life and better gas mileage. When combustion occurs it does not take place instantly. It requires a period of time. Depending on the RPM the power stroke can be .05 of a second at 1200 rpm to .0057 of a second at 10,500 rpm. 1987 Make HD Model FXSTC Hog Questions: How do you set the timing on a 1987 FXST Harley Davidson 1340 Via Email To set with a timing light: Remove the crankcase timing plug and expose the timing hole.

I am setting the timing on a 1970 XLCH and have the flywheel rotated so that the advancetiming mark is in the middle of the timing inspection hole. The circuit breaker cam follower is not on the high spot of the lobe of the cam. It looks like there are 3 cam lobes and the follower is half way between the first and second cam lobes. The advance trim controls how much the timing is retarded from what the factory engineers considered optimum. via  Reply. Enrico 3 months ago Hi there, I recently removed my TPS to check if it was faulty. The bike operated normally but it idled a bit low and the battery didn't charge properly and had flat spots at certain ranges as well.
By advancing the timing around 5 degrees you get quicker, more thorough combustion creating a sensation of quicker throttle response and a small amount more power. It has nothing to do with revs or rev limits. It's only harmful if it results in knocking, and slight advance won't usually do that.Timing Advance.Discussion in 'Sportster Models' started by marknett, Jul 26, 2011.
