Hello CBK and welcome to the ATV Connection. It's great to have another mechanic check in. I'll bet you will soon be sharing your experiences and problem solving skills with others, especially in the Honda brand forum.
Start a thread in the Honda brand section and I'm sure you will get good responses.
I've read posts by a fellow from England, username is merryman I think. I gather he used to work in a Honda ATV dealership and seems very knowledgeable on Honda ATVs and their transmissions. Search for him and his posts and you may learn some things about your machine's transmission.
