If some of you remember, I got a problem with my Pinasco 177 http://www.germanscooterforum.de/index.php...=1&t=21129&st=0

And finally I bought a new one, "Sprint Chris" said to reound the corner, but what else do you suggest ?

Sprint Chris, if you're reading what have you done to yours ?

hi

andre did most of my modification...

he made the pistons layout like a malossi (with the cif system)

there are pictures in the forum just search after: andre+pinasco

as far as iknow he lowered the exhaust port about 1 to 1,5mm and also higered it about 4mm

according to this the exhaust port gets wider from botoom to top

like this: ________________

-------------------

instead of a round layout

plus i made the 3 engine ports fitting to the pinasco ports

thats basicaly all

(took three days)

so long chris

He forgot to mention that this modification was done together with a new crankshaft.

In fact he has now nearly 195 ccm, which has a huge impact on the performance of the cylinder...

no i didn't forget to mention this

lorn already knows and also has this crankshaft :grins:

Thanks for the info, and I've found a picture,

but if andre has drawing of it, I'll appreciate. Or I'll go standard...
