OTTO DIY V2 Silicon Inserts


OTTO DIY created the V2 Upgrade Kit to bring some of the magic of the Korean lever offerings such as the Myoungshun Fanta and Crown 303 series to the Sanwa JLF. While it isn't exactly the same feel as a traditional Korean lever when upgraded, the JLF jumps into action with the awesome addition of silicon grommets instead of the standard bowl pivot of a standard JLF. This adds tension at the top of the lever and tightens up the overall experience significantly. Die hard Korean lever users will appreciate the update to the JLF and those trying to get a new lever experience without making the jump to a full Korean lever will immediately notice the tighter control it offers with the kit installed.

These new inserts allow you to replace the stock V2 Kit inserts and further adjust the overall feel. Each color represents a different degree of reflection offering up to 16 different combinations of feel when combined with the stock JLF spring or the V2 kit's lighter spring.

Included with this Insert Kit:

  • White V2 Shaft Core (replaces the RED core included standard with V2 Kits)
  • RED 40 Tension Silicon Insert
  • ORANGE 50 Tension Silicon Insert
  • GREEN 60 Tension Silicon Insert
  • BLUE 70 Tension Silicon Insert
