And in other news, Ryan Go dropped by from Milwaukee last weekend to grab a fairly complete Grande that I had lying around .... So y'all know what that means .... I lent it to him for R&D....
Vespa Cranks pipe in the works! I'm super super excited to see what he comes up with and ideally I'll have the dual carb engine running on this roller so we can test the pipe when he's done.
No more annoying ass proma circuits, and finally a decent vespa pipe! My hopes are high.

Also I don't think I mentioned this before but the stud hole on the pinasco case half was shifted off center by about 1.5mm from the stock location.
I couldn't get the jug to fit all the way down. So, I had to file out that hole on the jug. I just happened to have a perfectly shaped round file that made quick work of it. I tried to take a pic to show the misalignment but it didn't come out great so I won't even bother. But I took off a little bit of material and everything fits together snugly.
Lapped the head to the jug as well, on 400 then 600 grit sandpaper. Fresh rings, gap checked. Used piston but a nearly new cylinder. Once everything goes togeher this week I will make sure the piston clears all the ports, and then measure the compression to see where my starting point is.
I am going to try and run higher than stock compression and use a parmakit cdi box for the timing retard and I think that combined with the liquid cooled head should be able to keep the engine reasonably cool and free of detonation conditions even with the higher compression.
