Upgraded clutch springs from H-T

Has anyone tried these stronger clutch pack springs from Happy Trails? I am thinking that if they help the sticky clutch plate when cold, they are worth the 20 bucks. Also, A firmer clutch lever isn't a bad thing, but I'd like to hear a testimony from someone who is living with it day-to-day.

Clutch plates experience adhesion sometimes when first starting, after sitting in a bath of oil, despite the compression of the cutch springs. An inevitable characteristic of a "wet" clutch, I fear.

The adhesion is a function of the properties of the motor oil, not clutch spring compression, IMHO.

A "heavier" clutch lever's of no particular disadvantage, except in heavy stop-and-go traffic, or riding in a parade, when hand fatigue becomes an issue.

Yet, the KLR clutch as-built is rather robust. Unless I experienced clutch slippage (from all the magnificent power-enhancing mods I performed on the engine, like installing the vaunted PCV valve mod), I would not replace stock clutch aprings of service-specification free length with stiffer ones. YMMV; won't hurt anything to upgrade the springs, if the clutch basket will take the additional pressure. (Your left hand may not thank you, after a few miles of stop-and-go on the Interstate, however!)

Okay then, thank you for the information. I guess I prefer the wet clutch slip durability over its adhesive properties when cold. Maybe a thinner oil for the winter could be considered. Anyway, I think I'll forget it for now.
