DIY Budget ($140ish) Overrange Setup for Longcase Minarelli

[dcdirtrider]

For anybody who doesn't want to spend $300+ on an overrange kit, here is what you need for a budget "overrange" setup on a long-case Minarelli. I am currently running this setup on my 2000 Aprilia SR50 Minarelli. 








1) Oversized variator, (S6-5616634 or ‎MS-5112800)- $100(ish)

2) BWS 100, Jog 90 122mm torque driver- $30(ish)

3) Yamaha 4VP-17641-00 774x17.7mm CVT Drive Belt- $10(ish)



*The cheapest place to get the Stage6 variator is usually Brixiamoto ($100, in picture), since their US shipping is about $15. Just expect a month in processing/shipping time. Don't know about Malossi.



*The cheapest place to get the BWS 100 driver is AliEx, but expect it to be unbalanced (wobbly, in picture) if you get the cheap one from "Glixal" ($25). AliEx now has fairly easy returns, compared to the ol' "negotiate with seller" style, so it might be worth a shot if you're in the US. You can get a used OEM driver from Europe using eBay, or spend a bit more for the TWH/JISO (Taiwan) options. I have not tried the Taiwan drivers to see if they're any better, so this will be at your own risk. I do have the TWH unit sitting in storage, since the lip on the back makes contact with the gearbox cover. Maybe some shims behind the driver will help?


*And the cheapest place to get a belt is also AliEx, several belts options can be found for well under $10. I'm using one from the "CQZY&CY" store (in picture), and no issues so far after about 100 miles. If you're looking for name-brand belts, you can use the models Scarabeo 100 2T, BWS 100, and Aerox 100 to find belts. I've also used a belt that's meant for a Peugeot Speedfight 50 that has listed measurements at 770x18mm. So just another model that happens to have a similar belt size. Stage6's oversized/overrange belt is almost the same exact dimensions to the AliEx belts, but usually runs around $50-100 for a single belt in the US... gross. 


I am not a scooter/motorcycle tech, so try at your own risk. I have not compared acceleration, so this all might be pointless. However, ne benefit of this setup over the "professional" kits, the belt doesn't appear to make contact with the case-ribs so case modifications may not be necessary.  Anyway, hope this helps!

Where did you find that Kundo F1? Thats one hell of a rare pipe, even here in Europe! I sold one to someone of this forum some years back tho🤔

The exhaust? It's an SCR Corse, so nothing terribly special. Would not recommend buying it though, the bracket requires major modifications (welding/grinding) to fit properly.  I had to weld a washer on the end of the bracket to extend the slot, otherwise the rubber mount would tear, then the exhaust would fall off. Oh, and SCR's customer support was pointless when asking about the alignment issue. Just buy a C16 if you want this lol

Thanks.
That SCR looks like a direct copy from the early 2000's Kundo!
