My Triumph Rocket is down with a suspiciously low rear tire, and I'm just about flat out of rideable machines, so all this has added a measure of urgency to getting the valve clearances checked on my GTS300 so I might be able to ride it tomorrow during the predicted sunshine-y sixty-six predicted degree temperatures (F).

On went the front wheel chock for the lift table, then onto the table went the GTS, then under the GTS went one of my new scissors jacks.

I removed both lower rear shock bolts so that the engine could pivot upwards when the jack raises it.

I strapped down the front wheel to the chock and table, then, with Trixie adding some welcome stability to the bike, I applied some scissors jack therapy with a ratchet and up she went, dropping the rear wheel while pivoting the entire engine/drive train upwards to allow some workable access to the cylinder head area.

The bike is surprisingly stable as it sits, and I don't feel that further strapping will be necessary for this project, but I'm ready if it does.

I shall continue reporting my progress as it develops.

Remember, I am not a Vespa 'Tech', so this could go in all manner of unpredictable ways.

So far...

I'll also use this opportunity to clean up the engine area, it's pretty dusty in there.

Wasp Dad coming in with the subtle jokes.

Some food for thought: most of us didn't start off as Vespa techs. Kudos to you for embracing the challenge and best wishes for success!

Like one sports shoe company says- " Just do it". The more you think about it ,the worse it will become (in your mind). Once you get started doing most anything ( you dreaded doing) the easier it will become IMO. Also if needed -for tougher jobs ….consult Yoda !.

Ah, memories. Not a bad job, but it was much easier having the engine out on the bench. OTOH, it adds a couple of days to the project.

I find myself rechecking my feeler gauge work a half dozen times too...

I recently did the valves on my Liberty. Even with body panels removed it was tight to work on the head.

I realized right away that I could not hold the stud still while tightening the keeper nut.

So I immediately pivoted to holding the stud still while "snugging" the keeper nut and then letting go of the stud altogether and just tightening the keeper nut. Yes the stud moves a little so you have to start with the stud just a wee tad loose as it will tighten as it moves.

Then you check again with the feelers, for mine on the intakes I make sure the .004 goes in smoothly and the .005 has some resistance. I am shooting for exact correct tolerance/gap but if there is any question of error it should be just a tad loose and not a tad tight.

The second one went better than the first and the third one went really well. Note: On mine intakes .004 and exhaust .006

Interestingly, you don't have slots for a screwdriver to keep it from turning!

Something like this is very handy for that job. I use them on old Hondas.

Even with the slots or any type of tool I always got the feeling that no matter how careful I was the stud moves as it's tightened.

Even if you manage to hold the stud perfectly still it seems like it moves to be just a little looser as the keeper nut is tightened.

You have to estimate for a little bit of movement either way and I feel it's just easier to set the keeper and then let the stud go and just tighten the keeper.

I always check after any adjustment is made and tightened anyway. I might have readjusted the first one three times and the second one twice and I think maybe twice on the last one as well. Once I decided on a technique it went very quickly and was perfect when done.

True, that, but I'm anal enough to check my work 6 times before buttoning things up.

I got nothing. Turn the key and drive to the local scooter service department. I'm convinced this has nothing to do with saving money - you guys really like tinkering around with this mechanical stuff. Some satisfaction in; "Holy Crap, I actually fixed that".

Why did you decide you need to check the valve clearances in the first place?

It certainly wasn't my idea, but Piaggio says that they want those little flippy motor things looked at every 6000 on the HPE models. My GTS has 6700 on it, so I'm doing it to humor our guys in Italy.

I know how he ended up with the new date and the short post count. I'm wondering how that bought him half of a roundel already?

I suspect that there's some jess factor at work here.

Roundels are awarded on a curve. The first half roundel is quite easy. They get progressively harder -- a lot harder -- with each new half.

I have three roundels, two 'norma'l ones, and a third with the number 5 in it.

What's the number 5 in a roundel mean?

Is it simply a higher 'denomination' roundel than the single roundels?

You earned 5 roundels and have achieved 2 more.

It means five roundels. Before Jess coded that, the number of roundels became - um - excessive. So you have seven in total. The curve is pretty exponential.

Or logarithmic, as the case may be.

In truth, the numbers that the forum software actually uses are defined in a discrete table, rather than a perfectly smooth formula. And the table numbers are slightly -- only slightly -- off of where a proper mathematical formula would be. For performance reasons, I might yet switch to a formula, which might alter the roundels a bit. But really not by much.

I expect many howls, though.

Switch to decimal roundels at the same time to confuse em.
