I'm a Newbie and need help!

So I just got my new GTS Super Sport in January. I got it home and started to customize it during the winter months. Ex. Led front and rear lights, Black powder coated all the chrome parts and added sport mirrors.The bike only has 5 miles on it as of now and today I installed a Akrapovic exhaust and after a month of waiting for it a belt cover that I had powder coated Black.
I went to start it up after a month of not being able to and my EFI/ ASR light would flicker on and off each time I would give it throttle( not riding) Also it seems not to be running correct. I thought it might have been the new exhaust, so I put the stock one back on and had the same problem.
If anyone has an idea of what may be my problem please let me know. The dealer is a hour and a half away and I'm sure I voided the Warrenty with all the custom that has been done.
Thanks.
Joe

Did you recalibrate the ASR after changing the exhaust? (I'm assuming you have to take the wheel off to switch the exhaust, or at least you had to remove the wheel to do something.)

I did not have to remove the wheel to do the exhaust. But believe thats the only time you have to recalibrate the ASR.
Since the EFI/ASR light on the dash are together I am not sure which one is the problem.

If it was on the center stand it is normal for the ASR light to flicker. If you turn off the ASR it will allow the rear wheel to spin. Be careful the scooter could lunge forward.

If one wheel is at a rotational velocity that is different enough from the other, the asr kicks in and the light flashes.

It will engage on the stand as if you are riding as Piaggio havent added a kick stand sensor, and it knows the front wheel isnt moving but the rear is so it cuts power to the rear


If you read your manual, it would have saved you from swapping exhausts over.

To turn off asr hold the ignition button down for a while and the efi/asr light will appear on and static indicating your asr is switched OFF and you can spin the rear wheel on the stand as much as you have courage for

It is perfectly normal, as the ASR won't let the wheels turn at different rates. So while the scooter is on the stand and the front wheel isn't turning, the ASR will stop the engine from revving.

You can switch off the ASR by pressing the start button while the engine is running. The ASR light will come on and stay on. Then you can rev your engine to your heart's content.

I always switch the ASR off when I start the engine, unless I will be riding on wet or sand roads. I don't like that hesitation that is causes on take-off or going over bumps.

Thanks to all!

Everything working fine. I guess I should have driven the bike instead of just running it on the stand, would have saved me a lot of time and energy. Did not realize theses bike are so sensitive. I had a Piaggio's BV 500 and a Honda forsake before this one, but never did any modifications to it, so I figured I just screwed something up.

I'll just chalk this up to being a newbie in the Vespa world.
