Piaggio zip help please

Ok so my friend tried to clean my air box and ripped the foam in half so I fitted a foam stage 6 filter but now the problem is it bogs down and doesn't pull away I'm guess this is to much air? And not anough fuel? Well it's a 17.5 delorto carb with a 64 main jet.... What should I do? And no fitting the air box back on is not a option

 

you've answered your own question...
jet the bike to suit the filter

 

or when you were cleaning your air box some crap got in the carb so i would clean the carb it happened to me to !

 

What size jet would you say? It's a 64 now and bogging down to the point that it cuts out

 

You should try cleaning the carb as well that could be the problem

 

Tried a 85 main jet and the scooter is more powerful at pulling away but still at full revs it bogs down what could this be

 

What filter do u have, and what pipe

 

for standard peds, a 58 should be perfect, With exhaust and de-restriction 62, open air filter and pipe 92

 

i run a 70 jet with a air box and yasuni z pipe

 

It's a open air filter the exhaust is just a piaggio sports and all of you are telling me dif sizes 85 jet works best but only up to 3/4 revs at 4/4 revs the bike bogs and goes to cut out but back to 3/4 revs runs like a dream it's confusing

 

go full throttle till it cuts out and check your spark plug if its black your too rich and if its white colour its lean and if its brownyy colour its about right

 

85's to small if its open air filter..

 

So what size would you say go then? If 85 is to small like a 90? Before I had to change the air filter it ran fine on a 64 jet. It sounds like a huge jump 64 to 85?

 

no, not for an open air filter, and you will be getting too much air for your mixture, put a 98 in, see what thats like, if it still bogs, put a 106

 

If i was you i would buy a new foam for the airbox, your ped has not got a 70 kit so there is no point having a open airfilter as i will not run good and will just drink more fuel and make alot of noise, there will be little if any power difference with the filter (with the right jets) but you mpg will be way lower.... a pointless mod if all you need is the foam a malossi foam for the standard airbox is £6 with postage you will spend more money than that trying to find the right jet !

 

Buy jets from 100 - 110. its trial an error should be around 105 mark

 

It had a malossi filter in it with the 64 jet and I didn't want the open filter for power or sound I just like the look of them rather than a huge black box
