fitting a leo vince zx exhaust, no fuel line?

hi all, im sorting the jet and hats out of the way, im fitting the zx exhaust, i have taken my old 1 off and i have had to take an extra pipe off the standard one...looks like a fuel line or summit, the zx doesnt have a line in to put it back in its place...?

my bike is a gilera dna 50, help quick plz

 

im going to put a pic up comparing both exhausts...see what u think, i have just tried again and it looks like it will fit to the bike but looks as if it needs like, 2 blocks to put on the bracket b4 putting bolts thru. (which i aint got) and this tube....anyways u will see

 

okie dokie, here is both exhausts and u can see that ruber pipe thingy...what do i do with this...and do i just need to go to b and q for a couple of brackets...?

 

That is the cat-converter, which pumps air into the exhaust I belive, to make cleaner fumes. Or it might be the otherway round pumping fumes into the airbox to re-use exhaust gasses but im sure that would kill the engine.

Remove it, the zx dont have it because its not ment to be enviromentally friendly. You may need to upjet a little. 53 stock, 56 with cat removed then +5% for the exhaust.

 

yeh, that pipes for the emissions...and not needed now. You can also remove the box from the engine leaving just a stub of pipe sticking out :tup:

 

thanks guys, i took a risk and fitted the zx and just left that open, it must just be pumping out waste fumes so i have just left it open ended...i havnt done the jet yet because i cant get to the float bowl so im going to let a garage do it next week, it may have had an up-sized jet put into it before i bought the bike, if not...will it be ok to run for a week before doing the jet...?

i will upload some pics in the morning of the bike with a nice shiny zx on it imp:

 

personally I wouldn't risk running without firstly confirming its been jetted to suit

Things start to get expensive if it nips up just for the fact you dint swap a 50p jet

 

thanks for the info, im going to get ready now and try taking the carb off

only reason i didnt want to take it off was bcuz i dont know how the pipes go back on it...so im going to number them and take my time

let u guys know how im getting on lol
