Greetings everyone from a long time minibike, dirtbike, ATV, snowmobile, car, etc guy!

In 2002 I bought an ’86 Fourtrax 70 for my oldest daughter for her 5th birthday. It’s been a great little bike and all the kids have had a blast with it. No real issues other that general maintenance until now. Here’s where I need some help…

Suddenly, it won’t shift into neutral (and therefore won’t start). Rather than bypass the neutral safety switch I’d like to figure out why it won’t shift properly. It shifts into all 4 gears fine but not neutral.

I’m not opposed to pulling the whole thing apart and going through all the systems… it’s probably due! But before I split the case, are there any suggestions on how to get it to shift properly?

Thanks in advance for your help!
Paul
