Hello.
I don't know about any other post but this one is certainly here. Can you kindly decribe your issue in detail so people can understand the problem and possbly come up with a solution. There are quite a few experienced people here are usually quite willing to help out. Especially Alan, he is our resident genius!

I should note I asked this gentleman to come here to post his issue. I am clear he has a problem. I just need a little help figuring out what it is. His bike is somehow suddenly only going half speed?
