I have a clicking noise that I hear when I get on the throttle, that is annoying to me. But first a little history. When we first bought the trike, I was not wearing my hearing aids that I have had for a few years. I did not like the way they were performing for me, they just made noise louder I but I couldn’t make out what people were saying. But after selling our business property we were able to purchase the trike and we decided to make some doctor appointments to make sure we were in good health. And one of the things was to look at my hearing and this time go to an ENT to get checked out. I had gotten a pair of demo hearing aids for a week or ten days to see if I liked them. We made a couple of rides and I was hearing this rapid clicking noise. Just so happened that we needed to take the trike in for the 500-mile service to change the oils out. And as it happened I had an appointment to take the hearing aids back to the ENT. As I was getting ready I put one of the hearing aids in and the change battery sound was going off so I didn’t put them in, I just put them in the case to take with me. I drove to the dealership to drop the trike off. I mentioned to the service manager that I was hearing this clicking noise and I wanted them to check into it. But I mentioned that I did not hear it driving in. Minnie picks me up and we go to see the ENT. We walk out with a new pair of hearing aids for me and head home. The service guy calls and says they are done and I can pick up the trike. The service guy says nothing to worry about the noise I’m hearing. I ride home and I can hear the noise. So, if I have the hearing aids in I hear the noise without the hearing aids no noise.
Found where the noise is coming from
Minnie says she can’t hear the noise. I did some research on what might be making the noise. And I found out that the rocker arm shafts have a notch in them that the bolt is supposed to butt up against, locking the rocker arm shafts in place. However, the bolt hole is too large, leaving a gap. This gap allows the shaft to rotate and hit the bolt causing a tick. There is a fix for this. You can buy an aftermarket bushing that can stop the shaft from rotating. I bought the Rocker Locker from Custom DK Products.
I did the install myself, it took me about 3 hours to complete the job. I was a little hesitant at first. The fuel tank needed to removed and the valve covers look they would be hard to get off. But the job went well. I had to raise the back wheels off the ground so I could rotate the engine to get the valves in the “basic position” to release the rocker arm presser on the valves. Removed one shaft bolt, inserted the tool to align the shaft, inserted the brass bushing with a rubber mallet, re-installed the shaft bolt, torqued the bolt to specs and re-installed all of the parts.
Here are some pictures. I need to remember to stop and take more pictures. The pictures I took were to help me remember where parts went back when re-installing. But there are the pictures that show one of the first modifications that I did, and that was to raise my fuel tank. One picture shows the front of the tank raised 1 1/2″. One picture shows the back of the fuel tank raised up 3/4″. And one picture shows that the lift exposes more of the chrome valve covers, which make it look a little better to me, when they are nice and clean. But the main purpose of the lift is to let more air to flow over the engine and remove some of the heat.
I took a short ride around the block and didn’t hear the clicking noise, but later in the evening on the way to our HOG chapter meeting I could still hear the clicking noise. Looks like I have some more research to do. What a bummer. I guess I could just ride without the hearing aids.
