Martin, thank you very much for your informative reply. I had about given up on getting a reply since I checked back every day after posting for about 10 days, but had no reply.
I need a little clarification on the primary fixed sheave. Isn't it part of the clutch? If so, will the replacement part that you mentioned be necessary if I switch to the HiT clutch? I had gotten an email response regarding this question that said that I would have to obstruct the primary fixed sheave on the HiT. I am not real sure what that means. How is it obstructed? Or, would it be better to be replaced with the replacement you have suggested? Will the replacement fit the HiT without fabrication?
Btw, I am having to cut some "desires" out in order to keep the cost within budget. If I was going to change the variator, I would go with the Costa variator. But I have had to choose to go with the Pulley clutch and weights instead. Based on my goals, not only does it fit my budget better, but from what I have been able to glean from blogs, and other information both on the internet and from my mechanic, it may meet my goals better. I was not going to change the clutch, but it has been shown that the clutch greatly helps the Pulley weights and they work together for good effect.
Regarding the weights, 14 is the original weight? Hmmm. That is heavier than I thought. I thought I had looked that up on the Aprilia website.
What is your recommendation for the best drive belt to use and why? I don't have much experience with this, have only used OEM belts. But some say the Kevlar belts are the way to go because they reduce stretching, but others say that stretching is not that much of a problem and that the OEM belts last longer than the OEM belts. What is your take?
I am going to be putting on a Leo Vince exhaust, what would be the best choice for air intake? I was considering the XSH tuning airfilter, but I am unfamiliar with it. What is your recommendation?
Okay, I'll try to answer in short:
1) The primary fixed sheave you'll need is art no C8208 or KBR10004 (reinforced version).
2) All the gaskets are included in delivery with the KÜBLER kit.
3) I'd recommend using the MALOSSI Delta Clutch for your Atlantic 200, art no M5211821.
4) The torsion controller works perfectly with both the HIT and the MALOSSI clutch.
5) The belt PI833578 is no OEM part, we have removed the PIAGGIO logo so as not to confuse the customer there.
6) For the correct roller weights we cannot give you a weight that will definitely fit your scooter set-up. You'll have to experiment a little here. 14g should be the weight provided with the Multivar. Just order some additional weights to see which will suit your set-up best.
7) As you are about to change the cylinder and the clutch, we definitely recommend mounting a MALOSSI Multivar as well. The art no is M5111885.
8) We also recommend purchasing art no KBR10003 for the KÜBLER kit. See item description for information on what this item is all about.
