.@CROSSBOLT, txs alot
@MOUSEJUNKS, txs too, didnt know there were two versions,

EDIT:
since I do no offroad or have dusty conditions it became CROSSBOLTs version.

On my scoot was already minimal configuration, filterwise, just a very thin layer of foam, not worth to be called filter.

Decided for version "minimal minus 1":
-cutted this basketlike  part off (red circle)
-cut a fiberglass mesh into shape
-hotglued it in this frame (pls see pics)

Made a 3D scan before cutting, if I really need this protruding part, I might start the  3D printer.

Happy and safe scootering, Ruffus

By doing these mods to lower the temp inside the tranny, is it to extend engine life, improve mpg, increase acceleration and speed, all
of above?
2014 BV 350  "IndiGO" (fast, strong and tireless)
2006 Honda Rebel 250  "Snow Leopard" (stealthy, agile and durable)
2018 Lance Cali Classic 200i  "Black Panther" (smooth, nimble, quiet and quick)
2016 Wolf V-50 (sold)

Wanted a Kymco, ended up w a Lance, but that forum is inactive, so I am here

Extend belt life! Heat is the enemy of any flexible product.

Engine will last forever with reasonable care but tires and belts need to be cool to last.

You need a filter to protect the smooth pulley surfaces from dust and rocks which can be abrasive. The belt rides on these smooth surfaces so even a minor imperfection can wear out the belt prematurely. Sand or dirt or even road grime between the belt and pulleys may cause the belt to slip and lose power transmission.

The other reason is to prevent damage from overheating. The drive belt is made from kelvar and rubber and it's highly possible the rubber can be damaged or destroyed from excessive heat. The dry clutch has friction material which may glaze over from overheating and cause a jerky acceleration from clutch slipping as it has difficulty gripping the clutch bell.

Preventing overheating and entry of dirt will extend the life of all the components.

Duh  (me, not you CB)

Did not know that.  Knew it glazed over time, but not how/why.

Gone from knowing nothing 4 yrs ago to...knowing something, much in part to this forum.  Much appreciation to all those educating me.
