Just had my Rinny to the dealer for 1st service- 100 mile drive each way and $230 (included rejetting for high altitude)! Now I find I have an oil leak! A fair amount of new oil was on the cardboard I have under the machine this morning. I think the oil drain plug is OK, but due to a recent move I couldn't find my large metric sockets to check (is it about a 19mm?). Anyway the oil is around the two small holes in the plastic skid plate. So after I find the proper socket and check the drain plug, is there anywhere else the oil could be coming from in that area? It's not anywhere near the oil filter housing, so I don't think that is the problem. I may end up having to go back to the dealer thru some bad weather if I can't find the problem!
