Titolo: [English] Leo 150 problem when accelerating.

Again sorry by the language, but hope most of you can understand it anyway.
English is also not my native language, but i'm better at that then italien
:)
But to the problem.
Whan accelerating with full throttle from 0km/h the acceleration almost
slows down around 40-50km/h, and the engine goes down to a lower rotational
speed. The engine then accelerates slowly up the revs and from 65 the
acceleration is again normal. The same happens when i let go of the gas (has
to slow down sometimes, for corners and so on :) from higher speeds. The
acceleration is very slow around 50km/h, and the engine can't get the revs
up.
The leo has done 24000km and has a  freeway exhaust, but the problem was
there before that was changed. Since the topspeed is normal i think the
answer most be in the transmission. But the belt and rollers are fine.
Any ideas ?
(If i did'nt express myself clearly enough just say so, and i'll try again)
My own idea's that I haven't tried yet
1) The spring in the rear pulley has become soft, so the vario runs to high
a gear and at around 40km/h the gearing is to high for the motor so it can't
maintain the revs.
2) The rollers in there are supposed to be original aprilia spares at 10,5g
a piece. I could try some polini rollers at 10g or maybe some 9,5g normally
used on a 125cc leo. But i would prefer to find out what is wrong with the
original setup.
On another note
I have heard about the daytona camshaft which may give an extra horsepower
from several places, but lately i have also seen a Malossi camchaft for the
leo. Anyone knows the difference between them ?
Anyone has dyno-runs of tuned leo's ?

 can you understand my?
Yes clearly.
But the rollers are fine (i.e. they don't have edges) and they are aprilia
spare parts and have the weight the aprilia says matches the motor. But
you're also right that lighter rollers may cure the problems.
I'm just not certain that there are'nt other problems ...

Ps had a nice trip to Sweden today in good weather. The "ferry" people took
the leo for a moped which only costed 1/10 of a motorcycle ... :) But who am
i to complain when it saves me money


I think you have verified this part of the gearing, or not?
I'm not understand very well that you say.....
I remember you, my english is not very good! sorry!  :-(
Your rollers are equal that original aprilia?
Your strap is ok?
If this part is ok, your problem are other site. You thik this?
sorry for my reply repetitive!   BYE   :-)


can i reply directly on your mail in future?

 Your strap is ok?
Yes, both the belt and rollers are fine (all are original aprilia spare
parts). I have not disassembled the clotch end of the transmission yet, but
i suspect that the spring there is to worn down.

Hi Anders
first of all compliment for your home page: its very good and complete.
I think that rollers and the belt could be worn, but you said that they r
ok.
So it could be the filter that is dirty, try to clean it whit some petrol.
About the camshaft i know that the daytona give 1.5 hp to hight rpm.
The malossi isnt yet on sale. I asked them when it is ready and they said
that they are preparing also the motor 180cc. In july they COULD be
ready.......so it means in september!!!!!!
I wold like to know if u could give me the traslation in english of the
