Valve Clearence Adjustment on 1200GSA

[EasySushi]

Hi

Can someone clear the confusion for me?

When adjusting the valve clearance do you tighten until tight on feller gauge or tighten until you feel resistance and you can slide the feeler gauge in and out easily

Which is correct method?

Cheers

It's a 'feel thang' so a bit hard to put into words but, essentially you want there to be some healthy resistance to moving the guage but you do want to be able to move it, so don't 'lock down' onto it (or you won't get it out ).

Essentially, as long as it moves, the gap can not be smaller than the guage.

The difference, however, between a loose sliding guage and a tight sliding guage is neither here nor there so I wouldn't worry about it too much...........gone are the days when you could gap rockers with Rizla packets

If you shut a feeler blade in the middle of a phone book and drag the blade out slowly, the resistance you feel is how it should feel on the bike, assuming that you have a fairly thick phone book.

Feeler gauges must not be a tight fit, nor must you tighten down onto them. Make the adjustment in steps and the feelers should slide in with a small but perceptible resistance. You will know when it feels right. Do the other side then go back for a check!

If you don't know the answer - you REALLY shouldn't be doing the job.

if ou don't know the answer - this must be the first bike you've done

sure - we all start somewhere , but......

If we all followed that way of thinking, nobody would ever learn a thing.

Yet again it proves that there are 2 types of people on this site, people that are great at helping other, and people that have got nothing better to do then write totally pointless and seemingly useless responses.


Shame on you

i thought he was just implying it might be better starting on something cheaper

No, I don't think so.

Think what you like

Carry on then.

Good luck

Its your bike.

The feel you're looking for is tight but not too tight

loose but with drag

the phone book analagy is good - try that for starters.

Just remember

The consequences of being too loose are not as great as the consequences of being too tight.

Both quotes are good bits of advice, the Advwisdom is a good guide if this is the first time of doing such a thing, and using 2 feeler guages makes the job a lot easier if you don't do it regularly. also get a good light I found this makes things seem clearer when faffing about doing the valves, then get a manometer to balance the cylinders and you be surprised at how simple it is and the difference it makes

simple rule just take your time

I agree

".....If you don't know the answer - you REALLY shouldn't be doing the job...." This is very true. Don't learn the hard way on your expensive bike; get someone ( a competent mechanic) to show you on something less mportant. DIY may be OK when you are building a bookcase or repairing a kitchen chair but be sensible.

 

[its all poo]

oh its a GSA you know !

Oh dear ! why mention that it was gsa ? setting the gap on a tappet on any engine with a feeler guage is the same as when they were first invented !

don't mention the end float

rubbish, you'd never learn if you took that attitude, Ty's done the right thing he's unsure about a certain aspect of a procedure and asked for advice thats the correct way of doing something, encourage and support is the way to go not if you don't know don't do.

Ty crack on it's not hard just take your time if unsure ask away theres plenty on this site happy to help and give advice, doing something on an expensive bit of kit is a good way go as it make you more aware of what your doing

Why don't BMW use hydraulic self adjusting tappets? They've been around for years.

Thanks Roddy, and to those that offer support

All done and throttles sync'd using a twinmax


Cheers

Mechanical Philosophy Break…
Why all four at once? Well, You’re going to see some weird stuff happen when you
start wrenching on the valves – changes at an intake valve will affect an exhaust
valve, and changes at one intake valve will affect the other. Can’t explain it. Sort of
a quantum-tunneling problem at the mechanical level

Whats this bit all about. They cannot possibly effect each other or am i missing the obvious

doing two adjusters at once takes the slack up in the rocker shaft. some people think having the valves adjusted to such a critical degree is detectable while riding.

i'm not one of them.
