Alrighty folks, more news.
So, I learned tonight, there are two kinds of rear vario for a c2!!!
Well one part is different, the plastic bit! And this MIGHT be a part of my issue.
Here below you can see the two styles. Mine was the top, with these super cool sharp ass rivets. The bottom is a spare I had. Ignore the red for now.
Okay, so if you read this whole thread, you’d know I milled the spacer on the front vario to allow the front cheeks to close more, granting more belt travel. That’s cool, except what happens to the rear then? It must also give more and spread open wider to take up slack. The belt itself going lower than the ware line on that photo above and it’s possible the bottom of my belt is getting chewed up on those rivets. This is a theory and I can’t prove it as there’s not enough miles on it to show a new belt line on the rear cheeks. **** see a little side note about this as well at the end
So to help alleviate this I’m going to switch the the black plastic jawn. The cheeks themselves are different, so I’ll switch the whole inside cheek over. But also, since the black plastic piece just sits in the cheek, I’d assume you could actually grind those rivets flat and have no issues. What’s left of the rivets should act like posts to hold it in place the same way the black plastic piece does with the three black oval shaped nubs.
A little something else I’m going to try, this relates to the red circles in the last photo.
In the second photo what I circled is the same piece I have circled in the third. It’s a spacer to not allow them to close any more, I’m going to try and grind that down on the lathe just a hair to get rid of half that gap or even make them touch. This will make the rear belt ride higher at idle and apply more force to the front vario. Maybe not letting it slip?
To be honest I talked to Parker about his polini and Gila c2 builds. Both run the decompression valve head and he’s selling me one. I feel like this will actually alleviate the problem more than anything. Belt can’t slip if the compression is 0 haha ¯\_(ツ)_/¯
**** regarding to the stars earlier this is a little bit of a tangent. I also talked to Parker about windowing the front vario to get full use of the front cheeks, he has and he still can’t get the belt all the way to the top of the front. I feel this might actually be part of the back vario restriction, the plastic piece in question on this whole thread acts as a stopper, the front might actually max out because the rear can’t go any further. I’ll continue this post below so I can upload another photo to explain.
