When my bike is at idle and I blip it, it bogs a little, so I'm thinking I need to adjust my air mixture screw? It runs fine otherwise.

It's the type that sticks out and you adjust it with a 7mm wrench.
The thing is I can't reach the screw because the starter motor is in the way. Any special tools to get in there?

I had the same problem with my 2005 PX150. I bought a pair of 11 inch pliers with the tip bent at 45 degrees. This tool works fine.

I had the same off-idle bog and turning my idle mixture screw counterclockwise just a half turn solved the problem.

Seen pictures on here of spanners bent at an angle to get in there. Probably stuck in a vice, heated and bent over.

Lots of options, been discussed lots of times.

Here's one idea, use search for others.

I always use the search function first. With all things vespa, things change. I thought maybe after a while someone would have come up with a proper tool.

Thanks for the help and picture though
