I am cleaning the exhaust valves.....well, trying to! Here's my problem: I take off the spring clip and plastic cover. Remove the next spring....and then there is a small bolt in the center that is holding the diaphragm with the cable tie around it. I seem to be having a problem getting that bolt out because the head of it is made of plastic. I tried holding the diaphragm and turning the center bolt, but if I keep going this way all I am going to do is round off the corners. Any advice in how to get that bolt out without damaging anything?
This motor has over 5,000 miles and I can't say if these were ever serviced because I've only had the sled for a year. I'm thinking this is the cause of my problem.
Have I missed something or am I looking at this wrong? Please let me know. I found a thread on cleaning these from January and it gives some excellent advice in removing the valve......I dream of getting that far some day
