hello,

anyone else run a standard px200 with sip road and polini venturi?

i remember seeing a thread on here a bit ago but no one really had an idea of what main jet to put in??

iv put a 130 in atm but not sure whether to go higher than that and work down, not sure

will have to keep checking the plug in the mean time

anyone else running this combo let me know

regards

train driver had this set up and the main jet was so high it had to be drilled, bit too thirsty for a standard tank. pm him im sure he said 160

I've a Polini venturi on my Polossi Engine.

Setup is;
PX200 engine ported for Alu Polini with Malossi piston
60mm crank adjusted for Polossi
Sip Road or PeP2
Dellorto SI24/24

Main Jet; 128

Works really well and I can sit at 60mph all day with my PAV towed as well...

Rgrds

I was thinking about this setup but was told by someone that had tried it that while the performance went up, the fuel consumption went through the roof. I settled on the SIP road by itself and got some useful grunt.

Polini is a waste of money on the cost and the higher fuel bills ,i had to go up to a 140 and just as well of drilled a hole in me tank .

Now i just use the filter which seems to give almost as good acceleration without the fuel bills

I tried it mate, got up to a145 main and it was still lean and it was eating fuel.
spoke to a couple of people, Diablo said he set one and went up above 160 on the main.
I've been thinking of just using the foam filter.
I don't think the gains justify the extra expense in fuel.
Might be ok with the polini alloy kit I reckon.

Andy i have a 210 kit and i can notice the difference using the polini filter ,but it does run hotter because of the lack of fresh air (which is why my panel is being worked on ) but i did find that i needed a standard filter frame fitted to stop any fuel spitting back

bifter, do you mean the normal filter on but with the gauze taken out??

Yes Andy i had an old filter without the gauze and it seemed to stop it spitting back

ran a polini venturi and SIP road on mine, and only a 122 main. I put a P/V on a lads malossi 210 with a STERLING exhaust, and that only had a 130 main, both done loadsa miles. shocked to here of such big main jets. 160 main?
