Scooterotica

Anybody having problems with these? when pushing scoot through the gears, am getting a flat spot between 2nd / 3rd and more so 3rd / 4th, and when flat out and shut throttle off scooter cuts out! what the f*^ks that all about!!!
av blown carb out and petrol pipe out and alls clean! anymore ideas lads? head buster!!!!

ive had problems with 2 different kinds of FF tap for vespas, one a beedspeed one (blue anodised) wouldnt turn off. the other a SIP, again, would still flow fuel , albeit a slight amout , when shut off. try the float needle for wear, the extra flow of fuel may be overpowering a worn rubber tipped needle, and causing flooding symptoms.

cheers goldeneye, can't see it being needle but will check, gunna do a flow test t,mora! It,s 1/2 a pint a minute innit...

and ye right about the flow of fuel when the sip taps turned off!!!!! am sick as f*^k with tackle fanny shite people invent and sell, ye phone beedspeed and they think ye f*^king stupid.....BAH!!!!!!!!!!!!!!!!

I had this when running in a 166 did 1000 miles . No one knew why it kept dying as again it was when shutting off throttle . Would happen at 15mph as well as 50 MPH

We fitted a sip FF tap and it cured it for a short time before before the main engine seal went and engine went .

Interesting thread as could this be anything else other than the tap??

Even if the tap isn't shutting off 100% the float needle shouldn't be letting any more in once the bowl is full............. I'd be checking the float and needle before knocking the tap.

ive fitted one but havent really used the bike yet ...... did notice it doesnt close completely ........never had a problem with the genuine piaggio one just thought the up grade would be for the better........... back to standard tap asap as i cant be arsed on with crap relating to a tap

Have you tried the spring loaded float needle http://www.sip-scootershop.com/en/produ ... +_40090600

gunna order the 5.2 needle as i have the cosa cap on my 24/24, i,ve checked the existing 5.2 needle and float with a magnifying glass and can't see now,t untoward, but onwards and backwards.....

Have you looked inside the fuel tank?
