Modern Vespa

In the twist to start thread, I posted the following photo showing Gary's suggestion of removing the EVAP hose to check to see if that was the problem with hard starting. (It was.)



Note: The following does not take into account any laws or conservational value of the components in question. This is strictly informative, and is not recommended, especially in states with strict emissions standards.


What else can be safely removed to eliminate emission stuff that may have negative effects on the performance?

The above EVAP hose goes to a "T", with one leg going to the valve (item #10) inside the left cowl (with red cap.) The hose out the bottom of this valve seems to go back toward the fuel tank. What is it? And can this entire leg of the T be eliminated?

The other leg of the T goes across the engine bay, and into the large rubber clamp mounted canister (item #1) inside the right cowl. The hose coming out of it leads to the red inline valve (item #6) shown at the left in the photo above, and in turn, goes into the "Y" fitting at the intake, after the carburettor. What's all this, what does it do, and can any or all of it be removed?



Thanks,
Steve

Cheers Steve, I think you're the first person to even bother posting a picture showing that. I personally can't think of any other thing to change, besides the pipe that would help.
Also, from what I hear from Greasy125, new vespas that DON'T have a hard time starting, should just leave the evap canister connected.
Mine had problems until I removed the evap hose, but I usually love the environment, I swear.

if your bike is running right don't eff with it.
if it's hard to start, and you've recently had a tune up disconnecting the evap hose may help.
don't mess with anything else.
please.

best,

Okey Doke!

I pulled two bushel baskets of emission parts off of my '75 VW Scirocco after the warranty ran out. It got much better gas mileage, and ran better than the day it was new. Since that was the last carburetted car I owned (other than my current MGA) I didn't know if any of the stuff was detrimental to MPG and performance. If not, there's no reason to mess with it.

Thanks
