1. Completely Stock
2. + Leo Vince ZX
3. + Malossi 70cc and ECU

Surprisingly the difference isn't large between the 70cc with pipe, and just
the pipe.

I've been reading rave reviews about the Technigas RSII pipe. I also read
good things about the Leo pipe, but with a 70cc its causing some choking
issues.

There should be no warning light issues with the Malossi 70cc. Where are you reading this from tifofscooter?

Well, here is my revised list of parts for this year;
-Polini Fuel Pressure kit
-Technigas RSII pipe
-MHR VL13
-Polini Super Speed 9 vario kit with belt springs and wieghts
-Polini rear torque driver

Next order down the road will be;
-70 Malossi kit with ECu
-Delta clutch
-15/41 upgears



get the VForce3 reedvalve instead, the thinner reeds would benefit your setup better than the thicker VL13 reeds plus the VF3 has more area compared to the VL13. i have nothing but praises for the VForce3.

with your application i'd rather have you got a Yasuni Z or R exhaust, Technigas is really more of a toy pipe manufacturer unlike Yasuni who has real racing background in 125GP & 250GP.

OverRev-
I've been private messaging with some people on which
pipe to use for the ditech, and it appears that both the R and Z
are past the powerband.
I feel silly, but it sounds like the best pipes for the injector scoots
are the worst pipes for the carbed.

I've got Polini Black springs in right now. I would suggest green(?) or malossi yellow as these springs aren't quite stiff enough.

I've got a HiT clutch coming from Big B. Its all the rave on aprilia forums...
I guess we'll see what happens when it gets here.
BTW, I've gotta say the Technigas pipe is working great though.

66MPH is the new top speed. Regardless of it being down a hill, I could
have never, ever, ever gotten 66MPH out of a piped only zuma.

Sorry for not being around to answer this. Burnt, nice to see ya
here btw.

The bike is still not running. Last dummy move was accidentally
pulling out the wires from the starter button while transporting the
bike from the dealer(who decided not to help me, and void my
warranty because of an aftermarket reedcage)to my house.

Before that the dealer said it would start but not run well.
When I picked the bike up the throttle assembly and injection
assembly were not attached to the bike, but in the helmet bay.

The problem arose when I attempted to install the Polini Fuel Pressure
kit. I pulled the stock fuel bowl, and accidentally also removed the
regulator. Maybe I just have a bad regulator, but who knows.

Its freakin cold outside, and we've had loads of snow. Down since
August now, but thats the way it goes with scooter "tuning".

It's the HI-per2 models I thought.
