What? You thought that was the piston?

Nice tool, makes it look easy. I use one of those tough square shank Craftsman screwdrivers that fits the slots well & it's still a battle

I guess it kinda does look like a piston. Kinda on parr with all of the cylinder rebuild threads that are happening right now.

I made the tool quite a few years ago. I took an extra socket that I had, and then made a wide notch in it (can't remember how wide...1/4", 5/16", or 3/8?) Then I welded in a piece of however thick flat bar that was needed to match the notch in the cylinder stub. It makes it VERY easy to remove the stub.

I've been trying to upload the rest of the pictures, but my phone won't let me. I keep getting a "Unable to upload file. The given source has not been uploaded." every time I try to upload a pic.

I cut the neck off of the Sito as close to the weld as possible.

I fired up the MiG welder and zapped the two together. I also added two holes for the exhaust springs. I used a ball tipped carbide bit on my die grinder to create the holes.

I squirted it with some high temp exhaust paint, and then remounted it all back together.

I went out for an 80 mile ride the next day to test it out....and zero exhaust leaks!

Is this mod really needs for a Sito exhaust on a cast iron cylinder? Probably not?...unless you have a a leak that you can't get rid of. Where this mod does come into play is when you have an aluminum cylinder. It's not good to clamp down an exhaust to an aluminum stub. Over time it can damage the stub. I did this same exact mod on my Pinasco 215 kit a few weeks ago, and I have zero leaks on that scooter as well. I figured I'd be the one to spend the money to be the beta tester on these parts. I give it two thumbs up.

Thank you guys! The modification was one that I have been interested in doing for a few years, but I was hoping someone else would do it first so I could see if it was worth it. I think it might be a little over a little too over the top for most box exhaust systems that are mounted on a cast iron cylinder. All the parts rounded up probably costs more than most would want to spend on something so trivial....But if you have a persistent exhaust leak, then this might be the ticket.

I think the weld on O ring neck was about $35, the GS exhaust stub was about $40, springs are about $4 each, and the big pack of weld on spring hooks were about $12 (all USD). That adds up to one expensive Sito!...but it doesn't leak, so I'm happy! I'd definitely do it again.

Hi Whodat,

I remember back when this was started and being excited, and i was then offline for awhile and today got to burn feverishly through the pages of this thread, very much worth the wait.

Great stuff,

Thanks for providing such an entertaining build

Well thank you for following along Jackson! There's still a few more little things to add. You know it goes, a project is really never finished.

Since warm weather riding is pretty much a thing of the past in the Pacific Northwest now, it's time to fit a flyscreen on the PK. Looks are always debatable with screens, but no one can deny the functionality of them when it get wet and cold out!

I had an extra flyscreen from one of my P's, but it was black acrylic, and I wanted white. I found a NOS upper and lower screen that was white on (thanks!)Scoot.net. The older screens were bettter quality than the newer ones. I also search around for transparent pink plastic surplus to make the upper screen out of, but I couldn't find a tint that I liked. Then I took a closer look at the extra black screen that I had...and duh, it had the perfect rose colored tint. After all these years of using it (close to 20 years!). I guess I never paid much attention to what color it actually was . I had to get a bit creative making my own flyscreen mounting, but when I finish it was strong enough that it didn't vibrate.

I ordered up some Cycra brand handguard shields in a white (dirtbike specific parts). The shields are a different tone of white than the flyscreen, but I don't care. The reason for the shields is to help keep my hands warm and dry. Since the PK has grip heaters, I should be good to go for the rest of the fall and some winter ridding.

And a glamour shot of it. I think the white lower portion and the rose tint upper is spot on for this build.

Well about 4 months later and I finally got around to installing one of those old school PM Tuning "up and over" pipes. I've been intrigued by them for years, but never had a scooter that I would want to install one on. Months ago Roliver gave all of us here a heads up about a guy selling some PM Tuning pipes on eBay for cheap. I bought one and it's been sitting on the shelf...until a few days ago.

I did a dry fit on a spare P2 engine that I had on the shelf, but the PM pipe didn't fit that well. In fact it didn't fit whatsoever. The pipe is actually designed to fit the PX2 case. They're a smidge bit different shape, but when I held the PM bracket against my PX2 case, I still don't think it would have fit that engine either.

I took a flapper wheel and then a wire wheel to clean the old weld off. I made extra darn sure that i didn't grind into the pipe. Having the metal too thin there wouldn't be good for long term durability.

Here's a pic of the bracket that PM provided. It wasn't going to work whatsoever. I ended up buying a couple (and a couple spares) rubber isolators from McMaster Carr.

I ended up using zip ties to hold the pipe bracket in the correct position so that I could tack weld it into place.

Once the pipe was unbolted I finished welding it up. This is what it looks like after i used a wire wheel on the weld bead.

Of course I had to notch out the floorboard so that the downtube (or uptube in this case) would fit. I used a double sided flapper wheel. It makes it super easy to sand in a circular shape at awkward angles.
