jet kit from sipscootershop

[chimo]

Hi i wonder if someone could point me in the right direction. Im looking for a jet kit for my 2004 vespa px125 disc with a spaco si 20 20d carb. I want to drill the air filter and mount a sip road 2 exhaust which means changing main jet. Sipscootershop do kits but I cant figure out which kit I need. Is the standard jet size 98?

havent the manual to hand ,but memorys saying stock on a auto-lube 125 is 96 , 98 is for the pre-mix models .an expect ya to need to go up on a jet size for the exhaust an 1 more for filter .say a 100 , i'd start with a 102 1st tho. www.sip-scootershop.com/en/products/~/products/jet+si+sip+performance+100+_40261000 an www.sip-scootershop.com/en/products/~/products/jet+si+sip+performance+102+_40261020 . according to the spiel there better than dell genuine . tho i have always gone for dellorto genuine jets in the past ,here www.wasp-performance.co.uk/onlineshop/prod_1879367-Carburettor-Main-Jet.html . same price but cheaper postage ,an unlike others have never sent me spaco jets as "genuine dellorto" .

This thread should help:

Drilling Air Filter

Take the guess work out of it, pull the main jet out and have a look. there will be a tiny number stamped on it

Many thanks for your help. I ordered 100, 102 main jets and a sip road 2.0 exhaust and along with drilling the air filter i  hope this gives me scooter a bit more go. Have you tried the polini venturi air filter?

I packed cotton balls in my air filter, then a coating bearing grease on the cotton balls. All the swarf stuck to the grease and was easy to pull out with the cotton. a quick splash of carb cleaner, job done.

I bought it from easyparts.nl It was original filter for PX200 (2003 or so). To be honest, I didn't even know about drilling filter when I got this filter, with holes. Old filter was without holes. That's why I did some searches, and find out this drilling thing.

We've been through the ins and outs of the SIP jets somewhere on here before

If you want the best, genuine Dellorto is the only way to go.

The quality of SIP (and BGM) leaves a lot to be desired. The finishing off of the holes and slots are very very poor compared to Dellorto.
