What symptoms would you notice while riding if timeing was too retarded

[gryphon]

Hard to elaborate on the title. I was asked that question but had a hard time describing any symptoms that would be noticable while riding.

[Wicked]

In older days the motor would act "sluggish". Slower to rev up as in slower throttle response, but motor could still work without a hitch. Earlier HD's and V8's as well you could hear the intake sucking more...    Not sure on something injected though.....

[hrdtail78]

Might run hot.

[gryphon]

Yeah, those are all things I pretty much explained to the guy. As far as I could come up with there were no obvious and immediate signs (such as there are when your too advanced) though.

Depending on the type of exhaust some will sound dull not sharp for lack of better words to explain it.

[koko3052]

 :hyst:Exhaust will sound " well duhh?"   

[sfmichael]

motor will be lazy and not build revs/power as it should

[Ohio HD]

Exhaust will sound " well duhh?"   

     

[ScottyMoore]

engine will start well, but loss of power with higher revs, right?

[sfmichael]

yes, if initial timing is correct or fairly close
more accurately, 'lack of advance' (kind of equates to being retarded) will diminish the engines ability to make full power and performance will suffer

I love my lawn mower tech shovel, advance it till it pings then back it off, done. 

Yeah I know  = redneck.

I remember simple too.  Now just try to find a "thin silver dime" to set points gap with..............

if it's way retarded you'll get a drop in gas mileage

[JC 92FXRS]

The above are true....a couple of weeks ago I posted about a VOES connection breaking while riding.....changed the tone of the motor.....sort of hollowed it out....also drop in power at speed...cut my idle in half. fwiw and I'm sure you know, disconnected VOES will retard the timing. Didn't run it long enough for fuel milage.....but I'd bet it would drop significantly.
Cheers, Jeff

When I say cut power at speed...I mean when applying light power...wot, no too noticable.

I messed with the ignition timing, points, in a Triumph "back-in-the-day". Melted  holes right through the top of the pistons. Ran great until it lost compression.

Check your exhaust in the dark. If the pipes are glowing, or beginning to glow, it can be late timing and the unburned fuel / air mix is burning in the pipe.

How much timing are you talking about ? I am running mine at -3* from 2250 rpm to 4500 rpm. 15% throttle to 60% throttle.  Seems to run fine.

You mean you are running 3 less? -3 would really run like chit, if at all.

At partial throttle?  What about if it was too far advanced to start? 

Here is a spot where I pulled 8.. It's a little softer but it don't run like crap..

Might run hot.

IMO then heat is generating the in the exhaust when retarded.. Have you ever checked this when tuning?  Like the CHT is not to bad but the bike feels hot?

Max

[sandrooney]

Yes 3 degrees less than 0.

[HD/Wrench]

Max that  so where is the TPS at with that RPM??  TMAX still using table after table.

I have to admit I am using a slightly more modern lawn mower tractor as a benchmark.....

[Admiral Akbar]

TPS is along the bottom... Yep 1 table every 256 RPM..  0 throttle is about 12 deg.

Instead of a dime, I remember using a matchbook cover. Except now you probably couldn't find one, and it would be too thin if you did.
