Title: Idle Speed, No Tach
Post by ThumperPaul on 08/29/24 at 05:22:47

I know this has been discussed before, but it’s a worthy topic.

Idle Speed, but I ain’t got no tach (many people, stock bike)…. Actually, I have a decent tach but do I believe it??!

Idling too low is no good…. Bike barely has any oil pressure in the head with a fast idle…. I think the recommended spec is 1100rpm. I know some members have mentioned 1200-1300. My tach reads about 1250 when the bike is up to operating temperature. But, do I believe it? I’m gunna try to verify with an external tach, but will I believe it? Which one do I believe?! Average the results? Humm…

My ear is good enough to know the beat shouldn’t be as slow as Black Sabbath’s “Iron Man” intro. Don’t try to make it lobe like a Harley. Sounds cool, but deadly.

Is Led Zeppelin’s “Black Dog” too fast?

Is there a tune in the middle, maybe some Aerosmith or Pink Floyd??

IIRC a Redneck solution is get somewhere level, ish,, no strong wind, idle in first, Ottsta make 10 mph,,mehh,,12.. At least ten.. A higher idle doesn't come with a penalty,, a sexy loping thump? That is probably going to be expensive.

Ya don't Hafta start from a stop YaKnow,, it's okay to roll into a late night parking lot where stores are closed and slow down, drop into first,let it drop to idle.

When your engine is turning 1,100 rpm.....there are 550 exhaust pulses per minute.

Play the 550bpm and match the frequency with your idle speed!

Somehow I'm not seeing this as all that helpful,, but it's 550 beats a minute.
Or so they say.
Maybe if it was monotone, and with more of a Dyna accent.

Poke one ear bud in,turn it up to 11?
Put a hand behind the exhaust and listen?

Don't forget to stand it up some. Keep the cam happy.

Thanks for the reply. I get the concept, but I can’t get the metronome link you shared to crank up past 218bpm. It maxes out at 218. Maybe it’s my browser or I’m just not techno-savvy enough to figure it out.

Sorry guys. I didn't test the Google metronome.

All good, Ohiomoto!

Dave - Nice find on that one! Play that while listening to the exhaust and you’ll think you need a complete valve job! The tone of the metronome sound that is. The sound when you definitely need to check the valve lash! lol.
