Derestriction process

We derestricted our first Mio about ten weeks ago and from what I can remember, there were just two places to address. First, we found what looked like a bean bag in the air box that restricted air flow. Removed and tossed. Next was the ubiquitous ring to prevent the variator from reaching a higher gear. The removal process is to simply back off the variator nut (a hammer air tool may be needed), remove the restrictor washer (looks like a wedding ring for a giant) and again, throw in the trash.

Before doing this the accelleration was tepid and you literally hit the wall at 30 mph. After the two procedures, I saw 44 mph, which I think is an optimistic speedo but the engine was new and tight so maybe mid 40's is doable?

Hope this helps.
