question for Creeper

Regarding your "TDC-C is where you find it", great follow up and i THINK i finally get it, however i have one more than likely stupid question, when doing the valve clearences i should do inlet first followed by exhaust. Looking at a similar article the inlet is on the front side of engine(exhaust side of head), is this correct, and if so why is the inlet adjustment at the front and not at the carb side, the link below shows what i mean, thanks Andy.

Ain't none of my business, but . . . the linked process for sequentially adjusting valve clearance appears weird and arcane, to me:

Use kick-start to get inlet fully open then adjust exhaust valves.

Use kick-start to get exhaust fully open then adjust inlet valves.
In my limited experience, ALL valves on EACH cylinder of any four-stroke engine are FULLY CLOSED at piston TDC between the compression and power stroke.

Thus, valve lash typically is adjusted at this maximum mechanical separation for all valves, simultaneously; at piston TDC between compression and power strokes.

Thus, the admonition to open fully inlet valves to adjust exhaust valves; then, to open exhaust valves fully to adjust inlet valves, puzzles me.

Please explain; I'm totally ignorant of the bike-in-question, but--the procedure of adjusting valve clearance at crankshaft orientation other than piston TDC between compression and power strokes seems unique.

Hey man don't ask me to explain, thats why i'm doing it Creepers way, the method discribed in the link seems as they say" Along way for a short cut". No mate after reading Creepers original article and then his new and improved method for the mechanically deficient(i.e. myself) i quickly decided that Creepers method made sense, the only thing i need clarity with before i start is which side is the inlet and which is exhaust(i presummed that the inlet side would be the carb side but the picture points to the exhaust side).

Sequentially adjusting valve clearances, rotating the crankshaft between intake and exhaust valve adjustment, may be a matter of preference.

The advantage over adjusting all valves at piston TDC between compression and power strokes isn't obvious to me, but many procedures may effectively skin a cat!

There's no "one right way," certainly; best wishes in executing the method you prefer.

Maybe Creeper will explain, as in:

I think the thing to remember and what Creeper is referring to is that at one point," TDC-C"all the valves are closed so this makes adjusting them simpler, if my understanding of this is correct then what his method does is to give you a fixed point," i.e all valves closed" . I could be wrong though.

Not Creeper here, but yes, the inlet is the carb side.

I looked over the UK thread you referenced and while interesting, it does contain some questionable material. I'd proceed with caution, if that's your only point of reference.

Creeper gone Bye Bye...

I wouldn't expect an answer anytime soon from the great man.

Rumor has it that he lives in a shack by a river somewhere with no internet access.

Apparently his email in box was constantly flooded with emails offering him Viagra and ways to make his johnson bigger and he snapped wondering which one of his exgirlfriends has a big mouth...

What was worse was the constant stream of questions about LC4s, because he hadn't owned an LC4 for a few years and his riding had turned decidedly french (he has a Sherco these days I believe)...

Legend has it that sometimes he does dare to take a peek at his emails, but is still hit with a few emails every week that remind him that he no longer possesses a mighty Austrian steed, but a French princess, and a big mouth exgirlfriend.

It's ok kawadad i was going to use Creepers method anyway, it was only the stupid question i needed answered, and you sir have answered it, sending you a good vibe as of 18.44 gmt.

French girls are'nt bad, i had a lapierre and although she was slim and agile, she was high maintanace and brused my balls if i did'nt ride her "just right". Vive la Creeper.

Well did the clearences today, JUST, jeezo i hav'nt got big hands but that was a complete bar-steward to do. I did only take off the minimum of bits and i might have been better just taking the rads out of the way as well, i ended up having to back the screws out and just screwing down onto the feeler, i'm going to double check tomorrow as i think i may have dimpled the feeler while screwing the adjuster onto it and just want to redo everything with a clean feeler,(no dents).

Mountain,
It's a bitch.

Using a headlamp helps.
Loosen both valves, intake or exhaust, then reset each individually at TDC. Next do the other two together, loosen both and reset.

Bend the feeler end L-shaped at 30 degrees like a shovel.

Go slow, be cool!

It's a bitch.

Easier the 10th time.

Bill did them again this morning,"i was a bit less stressed and had a lot more light" made Creepers little tool for doing it, the motion pro copy. It took me all of 1 hour to do it twice( did it a second time for no other reason than i now can) to be honest Bill i think being a little more relaxed and having a proper tool to do it made all the difference, it dos'nt by any stretch of the imagination make me a spanner monkey but it doe's feel pretty good doing your own stuff.
