Anybody out there had any experience with nylon sprockets? Specifically the DuPont Zytel ST sprockets sold by NEP? Also, is the Tsubaki HSL (Heavy duty Self Lubing) chain that they sold with their sprocket as a kit really self lubing? Au Nguyen

Nylon sprockets work well if you maintain your chain and
countersprocket meticulously. You didn't mention whether its
for a dirt or street motorcycle but they do work well for both.
I would be hesitant to run a nylon sprocket on a street bike
larger than a 650 cc displacement.
I have never run one myself but a close friend did on a Honda
CR 250 dirt bike. He maintained it "fairly" well and chewed all
the teeth off the sprocket.
As for a "self lubricating" O-ring chain they do work well but
it is still smart to spray O-ring compatible chain lubricant on it
every 500 miles or so for a street bike and less for dirt. The
O-ring seals lubricant inside the rollers which is great but dry
metal to dry O-ring will wear out the O-ring.
Hope this helped... Is it springtime yet???

I've read of Joe Minton's (Motorcyclist / Rider magazines) experiences with NEP nylon sprockets and Tsubaki HSL self lube chain. He had it on a Yamaha XS650 (twin) and the results were excellent. I think I will put them on my KZ550. Au Nguyen "Keep warm, and watch out for ice !"
