Thats a beautiful scoot man,

I would have gotten the Aprilia but I was way to large on it...

Got a Super9 instead. I don't regret it, I think... 8)

The S9 seat is huge compared to the Aprilia. I prefer the ergonomically
thinner styled Aprilia.

I will be updating this page here soon. I have an order coming in from
Germany, really, really soon.........

Today I went to the store and bought some good ol' castor bean/premix
oil. Drained out all the injector oil.

Fuel lines are completely converted.

When the kit gets here, it appears as though the conversion will be quite
simple. Plug the CDI in, mount the new 70cc, pipe, plastic......mount carb/jet
carb, turn key, twist throttle, stare out the window at all the snow on the ground, go in and have a nice cup of hot cocoa, wait till spring.

A little update today. I went out to the beach to relax before graduation
the other day and snapped a few photos. I'm a little pissed at myself
today, I was attempting to put my bike on the centerstand last night, and it
fell on its side..... It now has what you could call "character", in the form
of scratches on the right side.

I promise to get videos up soon! One video of my scoot smoking a Morini
ditech-Malossi 70cc, and the other of a "power" wheelie.

Intake setup;

Current build:
-TP Due Plus 70cc
-Dellorto 21mm Black Edition
-BGM Shortneck Manifold
-VL13 Reeds
-Malossi E8 Filter
-Polini Speed Drive Torque Driver
-Polini SS9 Vario
-Polini Kevlar Belt
-Tecnigas RSII Pipe


Soon to come, Yasuni c16, and 13/39 primary gearing. This will be moving
my gear ratio from 13.2:1, to ~11.0:1. Average top speed now is just
under 60MPH.

You got some real nice stuff there for your 'Prila. The scratches will just give you an excuse to move to the next phase of all this.... painting. :D

That's a shame Mike :(

With the upgear and new exhaust it will be :twisted: a really fast daily driver!

Trog-
I really like the Kawasaki green color bikes, and was thinking about
painting mine the color green in the Italian flag.

Big B-
I am super impressed with the performance of the Due plus kit. I
can't wait to see what happens with the new pipe.

TP due plus

Postby F10Pilot » Sat May 09, 2009 9:18 am

That's a really nice SR - sounds like she's looking and going really well for you.

I'm curious about the due plus kit because they sell a liquid cooled conversion kit for minarelli that I was considering for my malaguti.

Have you found the performance to be comparable to an aluminum "race" kit like say an MHR or Manston replica kit?

Did you tune the kit or match the cases at all?

If its box stock and has ripping power it might be just the ticket for my project - just need to find a radiator and someplace to mount it.

Thanks!

I've had a few different 70cc kits:
-Airsal single and double ring kits
-MHR replica
-MHR A/C 47.6mm

I would put this kit closest to the MHR 47.6mm kit. Its super ballsy.
I think the Manston replica is nearer to the MHR replica, not the MHR kit.

I tried getting video last night, but my friend didn't make it to my house
till dark. I will try again today, and get a video up by Monday!

Hey Mikal

I'm about to take the plunge from injected to carb as soon as Josh gets the parts in! Can't wait.
Are you still running the RSII and how did (does) it perform with your carb set up? I'm going with the Stage6 Modular top end and am planning to keep the RSII on it for now. Might have to change it out for a Yasuni.

The carb setup has been holding out well. I commute 45mins in a car to work everyday so I haven't had much time to ride. I kept the RSII on, and it runs just fine. When reading the instructions of the Malossi digitronic kit, it tells you that the kit is good to 12k rpm. Running a race pipe and cylinder kit may not be an option with the conversion. Regardless, my SR50 is just about as powerful as my a/c race kitted-yasuni c20 zuma was.

You will enjoy it. My friend has the morini with 70cc inject kit, and he cant hang with me anymore.

Picture quality is poor. Sorry. Blackberry isn't the best camera.

A few things are new this year. Naked bars with Koso gauge, rear under
panel, pillon cover.

Today I added a 3 degree advance woodruff(spie) key.

I haven't ridden much this year, but I have figured out that even if I don't
ride much, I still like to blow money on my scooter. It may be the only
'really nice' material possesion I have.

Thank you. There is nothing custom about my bike, but it is one of a
kind. I'm starting to like the way it looks. If you can find my 2005 zuma
thread, you'll see that bar set up is not strange to me. :roll:

Its a work in progress. There are still many things I'd like to do.
