Hello, i have a yamaha aerox 50cc and i want to derestrict it by removing the washer from the variator. I have the correct tools and am able to legally do this as am 17 now. I just want to ask is it ok to remove this washer and by how much will it improve my speed?

Didn't know that was a restriction :S took it of mine when I rebuilt engine because I forgot it and didn't want to strip it back down lazy and lucky, what other restrictions are there on the aerox?

Theres one on the exhaust which includes having to cut of the extra pipe that comes out of it and welding it shut but then you have to up jet and everything so i dont want to do that. I just want to remove the washer to gain some extra mph.

Cnt advice of speed difference either mine had 70 kit on but fried cylinder so put a 50 back on it, by anychance do you know wha the standard size jet is?

Yeah its a 62 jet size

That's the main jet for it been as a standard 50cc?

yes

Thanks that's helped me out big style
