Vespa Shenanigans

So quite a bit has happened to the vespa since I posted last. I gave up lightening the brass weights.

It now has a Kinetic CDI... It's static which I hate. I absolutely hate hate hate that all of my bikes have static ignitions - it's just so dumb. Going to try and experiment with the HPI cdi box since it's fired by peak voltage instead of a trigger coil.

In addition to the CDI, I've also made some lighter weight aluminum roller weights for the variator. A lot of people destroy or flat spot their roller casings with "home made" weights, but I feel like this is because they use nuts etc. for weights - I purchased 11mm diameter aluminum bar stock to make mine, so there is no unsupported surface on the rollers. They're 2.8 grams and fantastic. I think this is going to be the next thing to add to the "davy sprocket" parts line on treats.



Right now the vespa is hitting 380*F ish... I attribute this to low gearing and static timing. Race gears are $85 and a variator is $110. I figured I'd go with modified stock on the variator and try to adapt an HPI box over christmas. I recently picked up a 12.10 carb from Brad to drill out to 13mm as well as a spare set of ramp plates to have a go at a notching attempt on. I'd say it went pretty well.
I stuck with 12mm notch height - the optimum range is 12-10mm I hear.

I tried to sorta match what the ramp would turn into at this point in the wall - we'll see if it does any good.


Obviously, how the roller is going to travel up the new notched wall.

This is how far out the roller should travel. Whether or not it's going to get stuck on the outer ramp plate is yet to be seen, but I'd say it's definitely a possibility.

Also, I go some new cable housing, some new bars, some new grips and some new tires! Huzzah! Finishing up the wiring and cables in my apartment before I sneak it back down past the RA's to be locked up outside :(
