I also found that the chain was way too tight, but at least the PO had replaced the stocker with an RK. I adjusted the chain and then lubed it with Maxima Chain wax.
The swingarm is really well built, and it incorporates a spring loaded chain idler.
I'll need to double check the chain tension when Linda is aboard the quad, but it's much better than before.
I also changed the engine oil, and used Mobil 1 synthetic 10W30, since there is no wet clutch to worry about.
