I'm really impressed by this 2008 CRF100 that I plated and have been running as a street scoot for a few years now. I'm also grateful for this forum and those users who take their time to post information. Thanks TT and thanks fellow users! Armed with little else than information provided from here mainly, the CRF has been an awesome street ride year round... sun, rain, ice, and snow. I've followed as much basic maintenance as I could based on instruction, opinion, and advice here. The CRF is half of my primary transportation "fleet" (CRF and a Honda street bike) and it does about 65% (maybe more?) of my local travel for groceries, visiting, etc. I'm surprised that it has held up so well. I'll use the search function but since I'm posting now, anyone have ideas or opinions on maintaining the stock exhaust for external rust? More specifically, is there anything I can do about surface rust or should it be left alone (perhaps acts as its own protective layer for the deeper metal)? Anyone else still running these Honda 100s plated for street?
