Aprilia SX50 derestriction

[benjjjii]

Hi, I have bought a Aprilia SX50 2009 and it is still restricted. I have taken out the washers in the exhaust. And I believe the extra pipe coming off the exhaust that doesnt go anywhere also restricts this?
Is there any other restrictor in the bike somewhere?

Thanks in advance

What sort of speed is it topping out at mate ? If its 45-50 then its fully de restricted

[benjjjii]

its about 43 it tops out at. I have a friend with the standard exhaust and no new air filter or anything like that and his aprilia does 60?
I also understand that its the same engine as the derbi's which do 60?
Thanks

If theres any emissions tube on the expansion chamber, then that needs taking off and plugging up/welded up. I imagine they will have more restrictions within the pipe aswell though possibly the CDI etc, but mostly its going to cost alot to get the thing shifting at an alright rate, so dont expect free things unless you can access grinders/welders easily. They will easy tell you they do 60, but only ever a real 60 after some proper mods.

Do a google on the SX50 and find out any common restrictions first.

Chances are you will need a new downpipe to derestrict this bike because it is such a late bike it will have a catalytic conveter fitted for emmisions.

Please go on just for once enlighten me as to why it's such a great thing to do to drag up on post on a 5,7,10 year old thread? What's the considerable logic behind it?

Did you search internetz and find a thread on here from all those years ago, and then sign up just to post on it? Is this what happens over and over again?

Not his gay bum boy mate by any chance are you?

Join a forum to be part of it, not just to get an answer to a question posted 10years ago, because your too much of a thick fuckwit to fix your bike.

Yay, three posts that are worthy of 2 abusives and 1 redundant.

The inner curmudgeon within me is now slighty less grumpy.
