Vanessa - Your question began a hugely valuable exchange of information .. I hope you read all the posts including the anti-clique posts, especially Saabsonette's in anti-clique, as to why the injectors can fail. The replacement clutch is only $3.00 I believe, very simple to exchange .. one screwdriver needed. I did mine at 10,000 miles. Also, getting dirt in the oil when refilling the oil tank would be a problem for the pump, and it gets dirty under the seat where the tank is, and there is a filtering screen to pour through we should always use if we use the injector, and I will continue to do so but I will be more careful about the clutch and cleaning under the seat. Best of riding to you.
