and put 2-3 holes in the top of the air box. also worth adding 1 or 2 tooth on the front sprocket to help stratch its legs

here's a vid of mine

do you know anything about different jets and sizes that i could use for my Carb? because i need to upjet it to use a decent airfilter and a better exhaust ...

I was planning on getting one of these air filters:

was 3/4 years ago i honestly cant remember and dote waste money in crap .. you seen my video that was just basic home hanywork ... and it was pinning the needle into the speedo housing 60+ mph reading

just get a end can for the stock expansion chamber dont faff with airfilters not worth the hassle bike will be a pig in the wet /damp . and jets i did the mainjet slightly larger and i changed them all from what i remember ring ur local aprilia dealer they will advise you on what to whang in it derestricted. but every bike is different so just a rought guilde i will try and find some old posts about what i did to it ><
