My 700 Base Model is sometimes quiet when I flip the lever and engage 4x4,sometimes just a click, but most of the time it's a solid thump when it snaps in. Normal??
Dropped it off at the dealer last Wed. They said they've never heard that before and would have to get with Yamaha. Warranty ran out last month. They're closed Sat-Mon so hopefully they'll give me a heads up today.It would be nice if Yamaha worked with them on any repairs. The thing has hardly been ridin. Like show room! Anyways I doubt that will be the case.You shouldn't be hearing any thump when engaging the 4wd. Sometimes you might hear a slight thump when coming out of 4wd once the spring tension pops the diff from 4wd to 2wd but nothing really noticeable.
That would be great. Still plan on switching over eventually like you did. I know the indicator light isn't really a big deal, but would like to see if they upgrade it a step further.On the front diff there is just a gear that slides back and forth to engage the 4x4. If you still have the cable actuator there is a heavy spring in the actuator itself that is quite possible part of the problem and I don't know of anything that could be done to fix it other than to go with the electric one. You can get the electric one from 501 Parts but it is costly to the point that I wouldn't do it without changing out the carrier housing to give you the diff lock with the electric servo.
Later today if I get time I'll take a couple of pictures of my old cable actuator where you can see the spring in it and understand where the noise could be caused by it.
