Hi,
I’m new here in this Forum and I can not speak or read Dutch. 🙁So I try to ask my question in english.
Do you have experiences with the above two cylinder kits?
I like to know the pros and cons of both with regards to quality, performance, life cycle and every other good or bad things that occured in your experiences.:Dcu,Ralf
.-{2F4OV}-.I haven’t driven with the 46mm Athena, but I have driven with the 46mm Pinasco.
This is a very fast cilinder (the black one). It is made of aluminium and therefore it has a good heat transfer ratio. But this is similar to the athena. The quality of the Pinasco is better. I think this is a pretty big diffenrence and it shows in the price of the cilinder. Which cilinder is faster I can’t tell. I think the Pinasco as well, but I’m not sure. So in my opinion quality is the headmaking diffenrence;)
Yes, quality difference was my understanding too. But what’s about performance? You say it is very fast. I don’t have an idea what this means exactly. Could someone make a ranking compared to the Malossi 46,5mm Cylinder kit? Not the DEPS.
As I have an engine with the Malossi 46,5mm I could get a feeling about what is very fast compared to the Malossi.cu,Ralf
there’s a thread on in this forum with a lot of good info on the malossi 46.5, pinasco 46 and a little bit of info on the athena. you can see it here; [url]http://www.vespa-ciao.nl/forums.php?m=posts&q=8098[/url]
i ended up going with the pinasco, though it’ll be some time before it arrives at my door step as i live in the u.s. and i had to order from fredHey terrydean, that link is a good advice. I didn’t realize that.
After having seen the negative statements about the Athena cylinder kits this option will be dead for me.
Hope you will tell us your experiences with your Pinasco kit.:)For me there are now only two options left. The very expensive Pinasco 46mm kit or the Malossi 46,5mm kit.
What cylinder should I use for my new engine project : simonini side inlet, 19er DellOrto, mono ratio 7:1, and simonini racing ?
So far I’ve heard that the Pinasco is making much mor RPM’s than the Malossi. Is the Pinasco the right character for my setup plans? :concu,Ralf
The 4§mm pinasco hava a lot of torque.The Athena revvs more.
Does the Pinasco have enough torque as it is bought or do I need to drill the boost ports first?
cu,Ralf
I would’t buy the Athena, this is why:

The exhaust porth in the cilinder realy sucks:o
AW50-4t | 13.13 | Gianelli Citypower | 3.2Nm@6000rpm | 3.0pk@6700rpm
Home made engine dynoThanks for the help making my decission.
I will now buy a Pinasco 46mm. Do I need to open the boost ports or does the cylinder have enough power like it will be delivered?
If I need to open the ports, what difference will it make in torque or RPM? Will I get more torque in the lower RPM’s ?cu,Ralf
p.s. could somebody tell me how to upload a picture in my post? I wanted to add a pic here but had no luck.
You can use something like imageshack and put the image link between the

.-{2F4OV}-.I think it will perform better if you open the booster ports. But I would try it first without opening the ports.
First ride it in gently than after 300 km you adjust it as you like, its better to give the bearings, cilinder, piston/rings a chance to adept to eachother and then go gently crazy on the ports.
Tip : Learn to make gaskets and adjust them to.(timing and stuf)
TICKLING BARNThanks for the usefull tips
@ Crullie: what do you mean with learn to make gaskets? From my simple point of view I would make cutouts for the boost ports into the gasket. Is there any special you could suggest?:|
cu,Ralf
What do gaskets have to do with timing?
like the frenchman did in the 50cc race-engine topic, he made a thicker gasket between engine an the cilinder, then the timing will change…. correct me if i’m wrong
my thirtiest post, i’m gonna get me a coffee:)*Edjuh: Right! Forgot about that*
