how do you get a polaris atv starter gear in?

Answer 1

I assume you mean the remote starter bendix. Depending on model it will usually just slide into place, but may require that you press it in careful not to damage it. By the way Polaris has kept my lights on for the last 5 years. they are junk. Get yourself a good Japanese quad!

Answer 2

Always give year, make, engine size and model # when asking questions. No bikes/quads are created equal.
Look up your quad at

Get back to me with that info, what picture you're looking at, point out the #s and be a little more explicit in your question. Get what in where?
