If you ride everyday "commute" rain or shine, clean chain WD40,then just use 90wt gear oil, have to do it every week and works for me cheap. Did it on my 1989 GSXR 1100 and my 98 TL1000R,no problems. The only small problem was when I first owned my 89 GSXR the manuel said to use Kerosine to clean the chain, don't do that, bad choice, WD-40 is a better Choice. My own opinion.
