jetting for a fully de restricted yamaha aerox 50

Just fully derestricted my 05 aerox (variator and std exhaust) and I am planing on fitting a malossi airfilter and was wondering what jetting you would recomend
any help much appreciated

 

the restrictions are usually two pipes that came off down by the manifold, they don't go anywhere and look like they dont need to be there. You need to cut these off and weld over the holes that will be left. there isnt normally a cone restriction in the standard pipes but always worth checking for one, it would be in the the down pipe straight off from the manifold.

the box you described is the secondary air system, its used to help 2 strokes pass emission tests as far as i no. There not seen on aftermarket exhausts so i suppose you could remove it if you liked.

then the bike will need to be upjetted and the rollers would need to be lighter to

 

Hi cheers alex for such a fast responce, I wasnt expecting one till tomorrow I think il leave that box i described on and remove the second pipe thats be pinched at the end.

I have just also purchased a mallossi air filter that I will be adding to my bike
what jetting would you recomend to a bog standard aerox full destricted inc pipe and also what weight rollers

cheers again chris imp:

 

can any body recomend what jetting to go for when its full de restricted and standard may add a mallossi air filter aswell if iv got one kicking around

 

lol is this the chris from preloved

its a forum and there is a person called chris on it with the same bike and asking the exact same questions to do with deretrcition and upjetting lol it must be you

 

i go on pitbikers uk forum but never heard of the preloaved one lol

 

have a search for jetting, its all over the forum and has been for god knows how long!

 

trial and error matey, i think the standard rox jet is 62 innit?

just buy some jets close to that mark probably a 5% increase

alright cheers dude

so am i right in thinking

if the std jet is 62 5% of that is 3.1 does the jet im looking for 65.1 ish

 

aerox jet is a 64 mate

Dellorto carbs

 

thanks for all the help last question though 5mm or 6mm Dellorto jet

 

and if you buy say 5 jets, then you can play about..

I've been told before .. No bike will need same jetting all are different, even if your "mate" has same bike. just have to play around with the jetting

 

5mm or 6mm ?

 

according to scooter attack, 6mm jets fit 12.5-17.5mm carbs and 22mm carbs

5mm jets fit any other dellorto carbs or summat along those lines
