I bought the splice diva edition (yes the sticker is already gone lol) and will be installing the firm spring. what oil should i put in it when i reassemble? I don't live near a bike shop so can i go to the auto parts and get some motor oil? if not there how about a motorcycle shop? Just let me know my options, and btw i am 210 pounds but not too aggressive so should i go away from the 5 weight?
