Great job as usual. Busy day in the shop.

With the 0.8mm packer it will go ok but the blowdown is getting big for that. Torque will be escaping. If you just put a stock gasket 0.2mm with the 0.8mm it will be 1.0mm.

Lots of pictures but can't make out the shape of the exhaust port roof. If its anything like the bottom of the port, it went well. If you can put some paper in there to make a port map, it will show the shape better. How you feel about grinding Nicasil now?

You got the crank cut. And split it to do it too. Must be great having all the tools to hand. Rotary ended plenty big enough as well.

SIP road chrome is just too loud. Anything is better than that. No experience with the FACO but I'm sure this is going to need some way bigger jets than the normal 225.
A fine days work

Wow SaFiS very nice. Certainly a productive day. Is the double o-ring lever for leaking? That seems to be a thing mine always leak with new rings. Amazing work all around.

Thanks guys!!

Jack, port pic following. Stock gasket is 0,13mm so I'll be adding two (top and bottom of the packer). Exercising on this cylinder was a bit nerve wrecking but I'm more confident now. The b@stard, did chip at me on one of the exhaust port corners, so I had to "reshape" it a bit just to avoid helping it continue. All corners chamfered and finished with a 2000 grit sand paper. One thing I'm in doubt though. All the measurements I took were with the packer in. That's how it supposed to be, right?? Or did I f@cked it up??

@hibbert: Correct!! Double o-ring to avoid leaking. I do this on all the vespas when I work on the clutch side...

Port shape looking good. Taking pictures down the cylinder often makes them look flatter. The corners are the tricky part. If this was for a speed tune, they would have needed moving. In fact the whole port would need re shaping. As it is though it will go well.
If the exhaust port is the 34.30mm you said from the top. Then all is fine. You went slightly over but no matter. Going to rev more, quite a lot more than the usual Pinasco 213. I think he'll be plenty happy with the power.

Never mentioned but this is ported for stock gearing. 23/65 and 35 tooth.
Be sure the squish is tight (1.1mm or less). 69mm is a big piston and we don't want detonation.

I would use the alternate German P200/T5 jetting as a base.
BE4 AC120 with 52/140 MJ130 and reduce main from there.
Timing at static 18 should be ok to start with.

Piston will be run in after a few laps around the block and the harder you run rings in, the better they work. Will be all ready for the roadtrip in no time

Just a heads up. Our "Paulo Pinasco" kit (as we named it) has been running strong, although hot at times. Torque is crazy and compared to another friend's "old" Malossi kitted PX, my friend is always one gear up. Following photo (max values saved in speedo) is from last week, on a trip he took to a nearby city (76Kms total) for a Vespa gathering. Continuous uphill for half of the way, two-up and WOT. SIP speedo is not perfectly calibrated and the 116Km/h indicated, is actually more. He now wants to try a 24 clutch cog I have on the self

How is this working out? Sounds like it performs as expected. If getting that hot and managing 9000 rpm on that porting, it is running a bit weak. Obviously not enough to blow up but still slightly weak. Up one jet size should do it.
It will pull a 24 tooth cog. I have a 24 tooth on a stock 200 box in my PX200 (very tuned iron stock cylinder with similar numbers) and it pulls as hard in 4th as it does in 2nd.

Jack, this was on a continuous uphill, with his wife, so it's not his everyday temps. He usually stays below 150C. Main is 135. We tried a 138 but it was bogging. Overall, he's very pleased and the FACO Box did a great job compared to the broken SIP chrome he had...

If only getting hot when pushed hard, then not so much of an issue.

135 main seems quite big. What are all the other jets in the carb?
And timing at 18?
