Do they all rattle when you start them hot on the sidestand?

[dern]

Noticed this for the first time yesterday. I guess all the oil had drained out of the right head and for a fraction of a second as it started it sounded like something was trying to get out.

I assume it's just part of the charm, right?

Cheers,

Yep.
Sit on it, get it upright. Start, ride away..

it's just the camchain tensioner taking up the slack as oil pressure builds.



er, probably

Lol. Filed at back of mind

Thanks

Tickover with uneven cold combustion is stressful to the engine. The engine warms faster and runs smoother under load so why hammer it for no benefit.

Just switch on ignition and climb aboard. By the the time you have pulled it upright, diagnostic check will be done so start it and ride away.

Ooops! This must therefore happen to my car engine every time I start it as the head is way above the sump...

Think about it... I think cookie has the correct answer .

I think you're answering a question which hasn't actually been asked. Did you read the OP?

Agreed, Cookie is correct it's the cam chain. In a car it's the oil feed to the hydraulic cam followers causing the clearances to be amiss until the pressure builds up fully, only a matter of a couple of seconds. The GS doesn't have hydraulic followers.

...but it does have hydraulic cam chain tensioners, which work in a similar way.

The police bikes have a big problem to valves on right hand side due to being idled whilst on the side stand (resulting in frequent valve replacement).

They have now been instructed to only idle them on the centre stand.

The Met also get through clutches in London in around 3,000 miles

Basically they are not paying so they don't care !

I imagine their mechanic/technician bods are royally sick of putting clutches in them....

i'm going to need the logic of that explaining to me.

I'm not sure why they'd need to idle for very long, on the side-stand or centre-stand.

My previous reply is a solution to the problem. Don't idle the engine on the side stand especially when cold and it won't develop a rattle on the RH cylinder.

Why? How can idling on the side stand make it develop a rattle? Genuine question, BTW...

Genuine answer: it'll end up getting so hot if you leave it idling that you will thin the oil enough to start a rattle. Leave long enough and the plastic oil level sight glass will melt.

Steady on the sight glass will cope with a lot more than oil temp at idling, or if you are getting over 200 deg C oil temp at idle you have a big problem

Simple this
"engine on if you are on the bike"
"Engine off if you are off it"
Can't see any need to be idling, other than operational police bods.

Never having been a fan of the way the 1200 Boxer Engine idles, I switch off at any occasion where I judge that I will be stationary for more than 30 seconds or so. Typical sceanario is at my local level rail crossing which is usually about a 2 minute wait, or at those temporary road works lights. I am getting quite good at judging just when to turn the ignition back on and allow the electronics to go through the pre-start checks, thumb the starter, into gear as the vehicle in front pulls away.

Little need for that even. On the RT-P the radio & blue/red lights all work off a second, slave battery. The LED's can last up to 18 hours, although the radio takes a bit more juice. Will still last for hours. No need to idle in most circumstances.
