I was reading Vespa forums and there were some guys joking about 49cc guys removing washers found on the outside of the variator boss, and risking messing up their cranks, as if this washer was not there just to limit top speed. I found such a washer in my 49cc Eton Beamer, but not sure if I really want to remove it (it is very thin anyway) So I just changed rollers in my vespa GTS300 and indeed there was a washer in the same place, in the case of the Vespa I have a hard time believing it could be to limit top speed, my Vespa will do over 80 mph bone stock. so the washer must be there to distribute the load between the variator outer shell and the boss, and/or to help keep the vartiator nut from loosening? Suffice it to say I put the washer back in my vespa, as it cost me too much to risk messing up  So what do you guys think about the washer issue? |

If the washer in in between the two pulleys then it is keeping your belt lower. If you remove it, your belt will ride higher, likely increasing your top speed, but also making you start off in a little "higher gear". As long as your belt doesn't ride so high that it comes off or hits the case, you should be okay, but people put things on scoots for a reason, and starting in a higher gear, I suppose, could do damage to your system. Also, if you go over a certain MPH, then you COULD get a ticket if you are driving a scooter that is not licensed as a motorcycle. |

OK so basically you aren't really talking about a washer but more of a shim that slides on the variator boss? If so we should stop calling it a washer because I think the point the Vespa guys had is people would open up the variator and remove any washer they found. Mine only had a very thin washer that slid onto the crank which I didn't think should be removed.

Some people put shims behind the variator to force the variator to start and end off a little closer to the outer pulley ramp of the variator.

To me, a washer is something you put behind a nut for support, and a shim is something you use to adjust things. Shims for variators usually come in widths of .004 to .04 inches, or 1/10 to 1 mm. |
