Looks like a very good site Thanks.
Nice A Speedengine made like a Simonini.
TICKLING BARNNice 🙂 also stole some pictures of vespa-ciao.nl haha
But what is this .. :pest
i think that’s the simonini LC Cilinder for Vespa 🙂 I see a picture of the Sprocatti engine that now belongs to Fredzzz on Barry’s worktable too 😀
oh yeah, finially I see someone who attached the waterpump the same as me.
I cant open the page, is the link broken or did something fail on my side?
That simonini LC cilinder looks like a normal ac cilinder, only with a kind of cheap looking watercooling pipes attached. It is in anyway not a very effecient way to cool it.
Can someone post another link of this page, because it isn’t working at my pc either.
It doent work at my place 2, but I want to see=)
Google cache doesn’t show anything two.
This morning at 6am it worked perfect.I would to send a e-mail,because I don’t like that someone take my pics,before asking.
The page is dead, indeed it has been working but now its dead

That simonini LC cilinder looks like a normal ac cilinder, only with a kind of cheap looking watercooling pipes attached. It is in anyway not a very effecient way to cool it.why not? i think it’s a good way to cool though. so you say Polini 60LC kits don’t cool good too? couse it’s not exclusively LC or exclusively AC, but both? now the core cooles better, normaly the core cooles less because it gets less air flow for cooling. and the ribs cool the same (good enough), because they get the same amount of air. at least, this is my theorie.

I would like to see an all liquid cooled cilinder over a cilinder thats air cooled, except having a LC addition. It’s transferring heat from only a small surface of the whole cilinder. It’s not enough to cool the cilinder only by the radiator provided. I would like to see that cilinder liquid cooled, because then you can replace the flywheel by a rotor ignition device, as in the sprocatti engine.
I don’t say 60LC kits from polini don’t cool well. This is something else. The 60 LC has it’s head only cooled by water. The system as shown in this topic is only cooling a small part of the cilinder, and probably not making contact that good. How farther from te heat source you go, the less likely it will be that the cooling device is effecient enough to be cost effective.
It’s better that the whole cilinder gets liquid cooled, and the flywheel gets replaced by a rotor ignition. This way you will have a lot more throtle response and a lot more cooling.
But cooling also depends on the type of radiator and pump used.
AC cilinders are really not bad , its true that it is to bad that there isnt a nice 46mm LC cilinder for vespa but i dont think its nessescery.
The huge advantage for vespa will be that you can safely put on a rotor, and get a cilinder with some more agressive timings.
I even saw a AC aerox with a stage 6 racing i think AC hitting the 18 BHP with it and do sprints with all the plastic plating on the scooter. So AC can be just fine to ride with because the vespa cilinders dont even get to 13000 rpm.
I can’t agree with you Kapot:
The part of the simo cylinder where the water flows is the right part, closer to the head is hotter, the polini cilinder is also liquid cooled in that area(not just the head like you said).
The head on the simo cylinder is air cooled , so I think you have the best of both worlds.
Also, both cylinders still have the forced cooling coming from the ventilator/flywheel, so I think both systems are efficient. Inner rotor ignition will not give better cooling because you lose the forced cooling.
much more throtle response :con. what do you think, LC scooters etc don’t have a flywheel? offcourse they have! but a plastic flywheel witch doesn’t weight a thing! how much response do you think it costs? if you place that on a vespa, a plastic flywheel, you have a flywheel anyway and you don’t remark the difference between riding without a flywheel or with a plastic flywheel. so a bit of creativity will do it.
