Yes it's an old thread, but the best topics never go away. How about a fully enclosed chain guard?
Tonight I ordered some brake fluid reserviors, inline petcocks and some 3mm 'Y' fittings from ebay, they were really cheap and should be here by the end of December, don't ask where they're coming from. Hopefully they'll be worth the $10 I spent and with some clear tubing, zip ties and some tiny diameter brass tubing JB-welded to the 'Y' fittings, I'll be able to put a pair of cheap systems together, one for my 650 and another for a Honda project bike.
I figure a small reservoir set to oil very lightly will be much better chain maintenance than my regular neglectful habits.
