I feel improved performance since I changed Carbs. Its Quicker both in response and in gear changes. Also its much smoother cruising.
And I also removed that case to air box spacer.
Now for a upjet and Sito plus..

I,m sure it will use a little more gas.But for me the the added performace out weighs the extra dollar I will spend.
I will do a miles test soon and get back to you..Brian |

It will use more gas. It's a general rule that the bigger the venturi the worse the gas consumption.
And, if tuned right and balanced with the rest of your system, the better the performance. Certain carbs ( like my Dellorto 25 phbl ) drink gas in comparison to carbs only slightly bigger or smaller. I'm sure there's some inherent inefficiencies in carb topology that contribute. |

I get around 55/60 mpg on my PX200 with a 24/24 carb and standard pipe. Mileage varies greatly depending on how much I thrash it. I've never actually sat down and calculated it.
It will top out at about 70 mph under 'ideal' conditions. |

Oh man...I really need to ditch my 20/20 and step up for the 24/24. My PX150 stock motor is very slow through out the gears. 1st and 2nd gear are almost useless. In 3rd gear it's very hard to get to 40mph! I am getting closer to 60mph (55-58mph) in 4th. I just need a little more power to get up the little hills around here and better acceleration through all gears.
So I need the 24/24, Sito, Upjet and I should be ok. Jez...more $ to spend |

Yeah, but if you do the 24/24 and sito, you're at least ready for when you upgrade the top end. You can stick with both of those for most top-end configurations and still be ok.
And i'm not sure how a 24/24 on a PX150 + sito works.. It might be ok, but there's a point at which your carb is too big for the rest of your system, and the performance suffers. I'm sure someone with experience on that setup will chime in. |

Really? So you think just the upjet and Sito should be enough? No need for the 24/24? I really want to stay away from kitting this thing. Since this is my daily rider to work I do need it to be closer to stock for reliability, but I do need to squeeze just a little more power out of the motor if I can with out compromising anything.

you absolutley have to listen to others,but at the same time others who have kitted there bikes may have made mistakes.
lets be perfectly clear when we say kitted i mean tuned as well. i had nothing to do with my tuned motor which is why it is reliable. with that said i will definitley never change a pair of stock italian cases again,never. now vlb,there is an option that we have not discussed much around here and i have had the work done and it is the reason why i am selling my kitted bike.(the other reason is i need the cash more than three bikes) the other option is what fullerton calls a 'super stock'(a great stock upgrade option) it includes a machined head from hot rod lightend and balanced fly from c lawrence jug ports opened and piston tweaked sito plus pipe my anti-kit bike is a eye opener and i will never buy a aftermarket kit again. i am sold on old school tweaking. you have to remember that chris lawrence has been tweaking 2t's for years. give him a call and see what he suggest. he has a menu of tunes for you. kinda like itunes for bikes. he can be your performance dj |

Px 150 with 24/24 is a good thing
If you are looking for better pep and pick up, I'd recommend the 24/24 over the 20/20.
My friend Joe put a 24/24 on his 2005 PX150 after he put the Le vince pipe (rightside) on it, and it really made a difference in my opinion. The throttle response is much better than with the 20/20. the 20/20 was ok but sluggish compared to the quick throttle response with the 24/24. He jetted the 24/24 like my stock P. My p200e has the 24/24 and stock pipe and it rolls quite well, on the road with other scooters I keep up with the GTS 250's except on top end. Another time I was riding on a long ride with another stock PX150 and he could hardly keep up with me, against the wind and all on the open road. And at Amerivespa on the long ride I was able to keep up with the pack of 250's no problem except again for flat out top end. For an old rat bike my P200 hangs in there well.....Stock. I figure if it ain't broke, don't fix it....when it does break, I'll get a 210 kit and pipe then. |

I Righteously Rocked!! a 118 jet with my New Sito + today much better on the end of the gears. 8)
Took my eight yr. old and I about 30 min. to complete the install . I recommend this pipe to all who can fit it with a 24/24 carb.!! I also think that old P200 pipe fits My Rally too |
