Thanks I will look into it.When I got my front brake off I found what on a car would be a bad ball joint,is that what it's call on this?

[oxidized_black]

yes, pretty much the same suspension and names of parts.

[farrier1]

I have all brakes cleaned.Anyone know what kind of brake fluid to use in 1995 polaris 300 2x4?

[oxidized_black]

it probably calls for dot3 but i would use dot4 ...

[farrier1]

I found it finally in that down loaded manual.Got starter last night and putting it in today.Back in my day when I have bike or car that sat for a long time I put a little oil in the spark plug hole the night before trying to start it.Is this still a good idea?

[farrier1]

I have most things cleaned or replaced good compression.Fired a few times.I pulled plug rusty water.Did this a few times then pulled head.Rusty thick watery mess cean out.but where did it come from.I don't think there is crank oil.Any good thoughts where it is from and how to correct?

i would think if there's water in the head it came from the gas tank or someone had it in water before it was parked ???

maybe with it sitting under the blankets, and so humid during the summers, the moisture was wicked up thru the carb into the head ??
