How to lower tickover...

[Robh1664]

Having balanced my throttle bodies a few months ago, my tick over is sitting at 1000rpm. How do I lower it a touch ?
Thanks in advance for the avalanche of helpful, yet witty comments (like do a serch)
Rob.

That'll be a tweak on your BBS's then (Big Brass Screws), and then do the balance again

With the engine warm and idling adjust each BBS by the same amount. Clockwise to slow it down.

Before you start mark the position of the BBS with a dot of Tipex and you can always reset it back to where it was. Tipex will clean off with brake cleaner.

Thanks Nige & Smug
I thought that the BBS was some thing to do with it.

Another weekend job to get me out of boring house and garden stuff !

Hi Rob,
Nothing witty - but bear in mind that the idle speed is meant to be 1100 rpm +/- 50 rpm, in other words, between 1050 and 1150rpm
By all means slow it down if you wish - but that is the specified idle speed

Cheers.................Grizzly

Oh, so 1000rpm ish, on the 1100gs is OK. That's good. I didn't check what it was before my first balance .

Crap........I'll be cutting grass this weekend then. But good the Beemer is in spec.

I have my tickover/idle at 700rpm , bike feels much more comfortable and relaxed, it's almost like an old Harley ticking over , potato potato . Just screw in the idle screws half a turn each side until it's happy .

 

[Robh1664]

Ok Step, I'll try that. Went out for a spin an hour ago (take away run). It does feel that 1000rpm is a bit high. I'll have a mess around and report back.

don't want it to low gotta get that oil circulation going around the engine mine is at 950 rpm

Well my bike has managed 80K miles of ticking over at 700rpm without any problems.

It's also a good way of showing any possibly impending problems. As if your engine isn't in spot on condition you'll soon feel it at a 700rpm tickover.

At that RPM the alternator is not doing much (if anything) to maintain battery voltage, especially if any heated gear/extra loads are on.
Are you ok with that?

 

[Robh1664]

I think I'll try for about 950rpm. If I have problems, I'll raise it a tad. My weekend of bike riding/fettling has been wrecked by the storm battering the south west. I love August

You better tell that to my alternator as he's been very happy with a low tickover for more than 13 years without any electrical issues in that time and with a heated jacket

I thought better of you than that - heated jacket is for pansies!

Of course you're right. I must go back to being a cold idiot and/or wearing many layers of clothing.

Nothing wrong with a low tick over, you spend so little time on tick over it wont have an effect on charging.

And those 600+ mile days in temperatures as low as -6

yes, that is ice forming on the screen.

Mmmm, interesting. Wonder if lowering the tick over would make much, if any, difference to engine temp whilst in heavy traffic?
