I run the original vario.
This contains 8 x Dr Pulley sliders 18Gr (2517-18G)

A Dr Pulley hit clutch, with 2 spacer rings under the original compression spring.

Ceramic coated downpipe from a Mp3 500.

Mivv exhaust.

The new HPE cilinder and piston from the newest type Mp3 500.
Compression ratio was 10,5 : 1.
Compression now is 11,0 : 1.

The rest is original.

The thin rear tyre is now 140/60-14.
The original high tyre was 150/70-14.

I see you put a lot of thought in your setup. What is your tuning target? The dyno diagram shows the acceleration rpm around 6500.

Did you see differences between the old and HPE cylinder?

For the HIT clutch there are different opinions to find. The theory sounds convincing to me, but I have not found proof (like 0-100kph comparisions) that it delivers higher acceleration. What is your experience with it?

Thanks for sharing all your project and insights!

With the hpe i can feel it has more torque.
I have driven the donor Beverly with the standard, and later with the Hpe cilinder.

The clutch works verry good, when the clutch bites, it bites and does not slip.
With the original clutch, tested in the beverly, it could slip through.
This is mostly from a stop to full throttle launch.

This is the setup, all the power is where i want and need it.
Setup is perfect.

You did serious project and built it almost from scratch. Glad to see that you had idea, good will, tools and needed knowledge to do all this. I know exactly how you feel when have produced your own dream-scooter since I build and drive something similar (Sportcity 350ie).
Enjoy;-)

Hello, yes i have seen that bike.
The donor for that was a 460cc Piaggio X9.
That was a more 'easy' build.
With big wheels, and a engine that is outside the frame.

I have seen more of these easy builds, that could have been mutch better if they took more time to do the build.

But most people don't care, they just want it to be fast.

You're totaly right- difference between your and this build is really big. We could see that you started with this project after longer research with almost unlimited tools availability, knowledge and experience. I'll say that budget wasn't bottleneck too;-)
I had issue with steering angle since my scooter wasn't projected for such speed- so had to increase steering angle from 25.5 to 26.5. I hope you'll not meet this issue but take care during first top speed testing.
Also glad to hear that in your country you didn't had more problems during "homologation". In my country they expecting so detail project with all posible calculations that's almost imposible to pass;-)
Stay well and fast and receive my congratulation one more time!

I have been secretly following this topic since the day you started building it but made an account to share some info with you today
The only reason why i liked this project so much is because there was 1 in croatia built years ago that was sadly crashed
It changed many owners throu out its life and the last owner was here in my city of Rijeka

Sad news- I didn't know.
Now I'm almost sure that this is only one in the world and based on owner dedication would run for many years...
I'm also almost sure that based on her car damage lady didn't had injury but just made insurance scam...
dOmo greetings from Zagreb;-)

Had some small jobs to do.
Had to change someting in the cooling system.
When driving verry slow, and running idle, the engine temp was getting to high.
I first thought that the original waterpump had not enough flow for the crossflow radiator.
But it truned out i had 2 airlocks in the system.
Changed the system, made 2 extra points to bleed the system and now it is all okay.

The flexible hose that goes to the air filter under the seat was mechanically to weak.
After 1000Km there were already 2 small holes in the hose.
So changed the hose to a modified Gilera Nexus 500 hose from the 2005 model.

The new flexible hose is thicker, so the plastic cover that was above the old hose has to be changed.
Now i made this from metal.






















The Gilera Nexus 500 hose, with a 45 degree alloy tube.




The metal cover is powder coated, and placed the Agip Sticker.
The Agip sticker is more correct with the construction year of the bike.









And today i drove it for the first time this year.
This was also the first time after the dyno setup.
The throttle respons is perfect, and the power....... bwah, nice!
Top speed, not tested yet.
