TREATS

So while waiting for parts since January to complete this project I stumbled on a new idea. TREATS hooked me up with this...


Simonini's complete 100cc engine. It's all there; engine, side intake, cdi, crazy flywheel, 21mm carb, pipe...



Now I just need to figure out how its going to fit in my ciao.......
I'd like to do it differently than others have documented before. The issue is one side of the fins.



As you can see the right side of the fins extend past the engine mount while the left stays pretty symmetrical. Rufus cut the fins and installed extra fans to help with cooling. Pink ciao from Europe created an extra area on the frame for the fins to fit.

Not sure what direction I'll be going, but I really don't want to chop those fins if I can avoid it as I'm pretty sure they're detrimental to cooling this thing. Vespa engines are traditionally air cooled and have fan blades on their flywheels, this flywheel is flat and round like a puch. I don't know how they expect it to cool properly...

Sealed Bearing Conversion pt. 1

So i you've never done one of these before, you have to first rip out the cup and cone set up out of the wheel. Mine came this way shipped to me. This leaves a space for a bearing. For my sealed bearing conversion I went to the local bearing shop and came back with a bearing that had an OD that fits snuggly in this space. The challenge was finding the right ID. They only make bearings in certain sizes. What I decided to do in the end was go for a 1/2 inch ID. WHAT!?! Not Metric! I know. The only thing that will be standard on my bike. I sold out, but I don't want to get some crazy weird metric size that I'd have to search and search for the nuts for. And since I can't use my original 11mm axle, I took it in a new direction. The plan is to do a bolt through style similar to the Kinetic setup (which I just recently realized has sealed bearings). One bolt that goes through and a nut to seal the other end (with the appropriate spacers of course).

The axle however was much bigger than the 11mm. So I had to make adjustments to the wheel hub as well as the forks.

Rear Clutch Discovery!

So I'm not convinced that a ton of people realize this...mainly because I've heard no mention of it before, but I noticed some differences in two rear clutches that I have.



So this one is the original clutch I was running. To my measurements it has a 9 3/16mm plate. It also has large clutch pads.









On closer comparison you can see that the second clutch has a larger plate (10 3/16mm). This would allow for more bottom end than the smaller plate. Since both have the same inner piece this would not affect top speed. This smaller clutch also has smaller pads.






The coolest realization from all of this came when I took the clutch apart to clean it out. The second clutch is stamped with the vespa logo and a "2". It uses clutch springs that resemble those used for non-variating ciao clutches...the first clutch has springs with one longer side. This means something to me because a while back I ordered variating malossi clutch springs from treats; tried to install them, but couldn't because they did not have the long side that was needed...See this link for clutch number 1 innards...Notice the long sided spring? The second clutch has same sided springs, making the malossi springs usable.

I'll try to get pictures of inside the clutches so that this makes a little more sense to people other than me...

Update!


So this is what the inside of the clutch looks like. Pretty much similar except for the small, even sided springs. You also can see the vespa and #2 stamp.

Finger ports

So in my waiting for parts, I started tooling around with a stock vespa cylinder. After consulting with a few others I tried out an idea to make finger ports. This borrows technology from a puch #2 cylinder (I think) and allows for extra porting on the inside rather than the outside.






If you have a stock cylinder you'll know what i mean. Those tiny triangle ports are now open since I cut the cylinder skirt away.












Will it pay off? Who knows!?! I hope to try it out this weekend while I CONTINUE TO WAIT!

Evaporust

I've read up about Evaporust. Apparently its a environmentally safe way to get rid of rust. You just soak whatever you want and then you can just dump what's left and it won't kill anything. I want to eventually try using this for my tank, but I thought I'd first experiment on my rusted triple tree.

Before:



After:

It ate through the rust, and also took off some of the paint (which I don't mind because I want to repaint anyways). It said that It wouldn't damage powder coating...I think it only took off paint because it was chipped due to the rusting anyways. On to the tank!

Comparisons

I thought I'd take some pictures to compare my new performance stuff with their stock predecessors. First up we have the carb. The Calibretta is sooo massive with added length and a giant expansion chamber.










Which leads to the cylinder. Check out the difference in exhaust ports! It's the difference between my thumb fitting in there vs. my pinky.












There are obvious porting and cylinder size differences...Not sure what I'm going to have to do to case match as there are so many more ports. I'll have to look at that when i get my new cases.











I couldn't find my stock head, so this comparison is between a 70cc Olmpia header...I'm probably going to run into problems with this bad lad as well. Hopefully it will fit...???










When comparing the flywheel for the cdi unit, I noticed that on the inside has a straight cylinder where it fits over the cdi as opposed to the mellow ramp of the stock flywheel. I'm sure I'll figure out why soon...my assumption is that is just the shape that needs to fit with the cdi.

Waiting

So I've been waiting for parts to arrive at treats...I'm getting a little anxious. I know that he has the best deals, and he's been the most solid in terms of getting parts shipped quickly...But I'm getting anxious. Mr. Malossi needs to ship the parts to treatland soon!
