My Sprint Scoot, SR70 MHR Speed

Sprengmeister

Xtreme SR Tuner
Hello,

now I want to present my scoot in this forum. I come from Germany so please forgive me that I have
to speak English (which is also not the best :) ). I drive scooters almost for 5 years, worked also for Scooter-Attack,
but in 2 weeks I have to go for 9 months to the army :(...
Some years ago I´ve bought an Aprilia SR50 www, which is air cooled. I´ve tuned it more and more after a time, at first only with
sport parts like Top Trophy cilinders, Tecnigas exhausts... after some time I switched to mid race with TOP Nardo exhaust and so on, was an
exciting feeling at that time :).
Last year I´ve decided to build up a Sprint Scoot, which is liquid cooled.

Unfortunately I didn´t think about to buy a piaggio engine, I´ve decided to take my Minarelli engine.
At first I wanted to take a Polini EVO cilinder but after a time a thought about the MHR Speed cilinder.

I´ve bought all parts and after some weeks I had them here at home.

I had also a second Minarelli engine for my scoot of a Malaguti F12, which was at this time fixed under my scoot.
I took my original engine and brought some parts to Koopmans, which is 300km far away from here. At home I´ve prepared everything for my project.

The exhaust is chromed, some parts polished, a friend made frame bars of V2A steel for me, some parts were painted and so on...

Last week I was at Koopmans on the dynojet and had around real 18 PS, perhaps I can achieve 18,5-19 PS in the near future but it is Minarelli, not Piaggio...

So this is my setup at the moment:

MHR Speed cilinder stage 5 fkt
Carters stage 3 fkt
Engine prepared for Overrange
MHR crankshaft
MHR Overrange KIT
MHR Delta Clutch
MHR Wingbell
MHR Air Filter
MHR Innenrotor
Mikuni TM 24 carburateur
Yasuni C20 exhaust
+16% gearing
TOP gearingcap
Short Tommaselli gasgrap
and some little parts... :)

In future there will be also a AIM digital revolution counter
Which optic-parts are at the scoot you can see on the pics which I will comment a little bit :)


This was my scoot 2 years ago, looks very original

Thats how he was summer 2002, some optik parts were there and a little bit mid race stuff, but air cooled

So I put the engine with a friend under the scoot, the front-rim is of a benelli and the back-rim of a F12, only to test the weekend
The other parts were painted

After some days, i put the first painted parts at the scoot. The black/blue lacquer is from BMW, the other is neon-orange.

How nice Carsten!!
I already told you the scoots looks pretty good, but telling it again wont hurt anyone ;)
Next time we meet (@ koopmans or something) we will do a little sprint! :*
 
ThanX a lot for all replies!!!

The chroming of the exhaust had cost 70€, the 2 running boards where your feet are on had cost 60€.
The cap in front of the waterpump is a chromed one of TNT, the cap in front of the Overrange is polished, will be chromed in some weeks.
Hehe Mol, ok, I´ll be there someday :). But I have to match each part with the other still a little bit, it´s not soo perfevt but we will see....

Have a nice day


Ciao Carsten
