I just installed the Kwaker 92081-1760 springs, no test ride yet. The Kawi springs measured 91mm long with approx. 5 turns per inch. The stock springs measured 103mm with approx. 3.5 turns per inch. Both springs are approx. 14 mm OD. The wire gauge appears similar. My "good" caliper's battery was dead, & the cheapo plastic caliper isn't precise enough to measure the thickness; to the naked eye (at least mine) they appear very similar, if not the same.

On my last test run the bike pulled strongly with the 158 mains, no shims, & stock springs, however the plugs were on the lean side of optimum afterward, so I'm going to try 160 mains next.

I want to run the bike with the new springs first & no other changes though, time & weather permitting. More to follow as available.
