Valve adjustment.

[Richard Stallard]

A while back I read a wonderful funny procedure, for valve adjustment on GS1150's anyone know where I can find that thread? As my brother is going to service my 1150 ready for me to go to Spain and I said I would send him the procedure.


Cheers Lickardo.

Wow...

That was fast thank you thank you thank you, Oh magic camera operator!!!!

How you doing haven't seen may pictures from you in a while?

Cheers Lickardo

Somewhat over the top. Wait till Steptoe sees this. He'll have something to say.

 

[hodge1150]

thanks for the info

Browsing thro earlier, thanks for the info on valve clearance checking (idiots guide), Ive never attempted it and in the past paid Allan Jeffries m/cs to do it. Have just completed the setting of clearances, doddle + the satisfaction of knowing they are spot on. Still might check them again next week all the same.

You need a thin 10mm ring spanner, motorworks in Huddersfield sold me a second hand one for a quid - great service.

Did mine and bro in law's ( sprout) this year for the 1st time . Real easy. Bike has never ran so well, all lovely and smooth,and quiet ( for a GS)

I believe this is the northern tosser in question who mostly runs around

Quite some pics from me lately in the forum

Cheers, Margus

Anyone know anything about the new K1200GT valve clearance adjustment ?
I have read that its done by computer, sounds like journalistic crap to me
(no, not MCN this time)

 

[(RIP) Bin Ridin]

The cost of the job is done by computer.....

 

[Timolgra]

There can be some very elaborate methods but....

Remove rocker covers and spark plugs.

Remove the two plastic cam sprocket covers.

In gear and turn the engine until the two arrows on the cam gears are horizontal, if no valve clearance turn 'them' 180 degrees. (inlet valve will have just closed when on correct stroke for setting)

easy peasy

You can do it without removing the front cover too, by using a probe in the spark plug hole to detect TDC. Suitable probe would be a length of wooden dowel, something that won't damage the piston. Turn the engine over by selecting a high gear and rotating the rear wheel.

good call, but put your thumb or finger over the spark plug hole when turning the wheel to feel when it's on the compression stroke, then use the probe to get TDC. you don't need to bother removing the bung to check the flywheel

don't set the tappets on the exhaust stroke

 

[Mouse]

Yes I suppose I forgot to mention that ... I would just determine the correct stroke by looking at the valves, but a "step by step" guide should mention the fact that only one TDC is the correct one

 

[Steptoe]

I didn't realise checking/adjusting the valves was so complicated .

I've been using the easy way all this time, i must try harder, and make things more difficult .

Remember it's an american guide, why write a sentance, when you can make it into a paragraph.

 

[ELIMINATOR]

Ah,the cavalry's arrived.

Everything abaht the GS is complicated What oil to use, etc.

Each time something comes up, there's a more complicated way to do it, or someone has a different opinion.

Still good news though Steptoe, keeps you employed.

So.................... what would happen if the valve clearances were NEVER adjusted. I suspect they loosen up, & don't tighten? How many cars with tappets were left unadjusted for years. I think the servicing schedule just plays on our paranoia.

Not necessarily. The valves can recess into the head, closing up the gap. Which sounds nice and quiet. Until the valve burns and drops into the combustion chamber - KaaaaBoooommmm

 

[ELIMINATOR]

OK, you've played on my paranoia, I've just done them. 2 exhaust valves a tad tight. Also think that BMW mechanics must have their torque wrenches

a) out of calibration.

b) Not set right.

c) What's a torque wrench?

Seemed way too tight.

Seems to run better, although that's possibly in the mind, was going to attempt physcological but thought I'd misspell it!
