i ordered 5 tungsten balls from rekluse. i put them in. its a little draggy, but im using the same spring/locknut setting as before. same gap, idle and spring setting. how does it engage? almost immediately, right off idle. total hookup. still very smooth, but torqier (sp?). the engine is doing alot of the work and the clutch cover temp has dropped dramatically. this is with 14/48 gearing, though. i want to gear it with a 47t rear and use a 15t for desert, 14t for tight stuff. it feels like it needs 1 or even 5 more heavy balls to tune it to a 15t, to make it perfect. its close though. rekluse should include 3 tungsten balls with every 426 clutch they sell. that would make sense.
