So here is the side view.

The needle sits well and closes well, I can tell by blowing gently into the gas line port.




If I tap the carb body, the needle does fall down a few mm.  Is this normal?

Carbs are now apart, in the ultrasonic, then getting a blowout.  BRB...

Looks like it is installed right. When I installed the vitron's in my carbs I noticed that the tab that pushes on it needed to be adjusted because the new needles stuck out of brass valve farther and caused the fuel level in the bowls to be too low (maybe I have the wrong needles?). Do you have a side view of the carb with the needles in showing that flat brass piece the floats push on and does it look level?

Turning Wrenches / VM28 Float Needle

I am having fueling issues.  Bike will not start.  Petcock flow tested fine.  A tad of fuel into the plug holes and it fires right up, but doesn't keep running.
I have suspected float issues for some time, I replaced the float valve with Viton last season.
Question I have, is this the corr3ct installation and orientation for this type of valve?  My old ones didn't have any little clip on them.  Can I run without these clips?

Finally got both of them up to snuff at the same time! Wishing I was heading east with them

Is there any secret recipe on setting the mufflers to get the distinctive 2-stroke crackle the way you got at 1 minute mark in this video below?

Now that's a sound with Authority!

No secret recipe. That first start video was in the garage and it was all closed up. I did repack those Spec 2 silencers years ago. When I did that years ago I thought it got too quiet. My thrasher bike with Toomeys I have never repacked the silencers. It's loud and I love it. The 500 sings a good tune also. I'm sure your bike will sound great with those (Toomey?) pipes although the silencers look non-Toomey. Good luck.

Yep the history on that motor is a mystery and it sat for at least 5 years before I got it and porting and machine work is unknown as well. If time permits I will at least stick my borescope in the LH cylinder and look for carnage.

bummer! Sorry to hear the news Tim, but like you said it's better to happen near home than on a trip in another state.

And a few seconds later, holy smokes, they moved Julians bike just left of center in a really cool spot. I was thrilled to see it out of the previous spot. Sent Julain a text right away.

After that excitement wore off and a few seconds more walking, holy smokes again, they moved the 500 front and center about 50 feet into the building. Yes, I was elated.

Looks like a great show. Thanks for sharing your photos and story.
Congrats on the revised placement!
