Modern Vespa

My tubes inside the swing arm are sticking out about like 5 mm too much on one side they aren't playing nice and I can't get them in any farther even though there is a good gap in the center. I tried heating the swing arm case and rubber mallet with minimal results. Any suggestions? I am trying to mount the engine

Never tried the clauss PU mounts, but word among those I know who've used them is that they vIbRaTe like hell.

You can use tire mounting paste the next time you try to install silent blocks: it helps things slide.

The engine, she is in! And the t5 carb box fits nicely. not sure what would be good to do next, cables? Electronics?

So far as I know, credit for the idea of using an inclinometer goes to Scooter Republic, the Buzzwangle inventors.

Now a decent inclinometer is pretty cheap, like $25 on Amazon. But the CNC'ed attachment tool they provide, along with the piston stop, which is redundant for me, made it hard to justify the cost.

What I did instead is tape a neodymium magnet to the back of my inclinometer, stick that to the flywheel, and do it that way.

For whatever reason, I decided to work this out to deal with checking the Sprint's timing over the weekend and once I sorted it, the entire process took about two minutes, plus no messing with attaching paperclips to the cases, sucking my printed degree wheel into the flywheel (yeah, I've done that before), or any other complexity. And as an added bonus, the arithmetic is easier, too.

Here's my specific technique, with pictures, and happy timing, everyone!

Use a piston stop, should be found at the local auto parts store= lifesaver.

that's going on the list!

I've got an M7x1.0 tap and die if you want to chase the threads on the original studs, or the case.

It looks like all the parts are there.

There's a 12 volt version, and one that doesn't say (I'm guessing it's 6 volt), but they look the same, so not sure which it is.

I thought all of those were 12V. They don't make a 6v that I have seen.

it seems the piston stop is Italian because I see bloccapistone on the tag.

The tag shows the end of Buzzetti, which is Italian, but it also seems to show the last letters of "Taiwan".

In any case, it seems to be a one size fits all affair.

Having several scooters with different combustion chamber architectures, I made a modular piston stop out of a hollowed out spark plug, and a long bolt. Cheap, works great, and you can adjust the length of the bolt to suit different needs.

Scooterwest rocks 2 day shipping pretty consistently. And it seems the piston stop is Italian because I see bloccapistone on the tag. Excited to carry on until the next "damnit I don't have that…."
