Hello

I'm trying to find information on where to get an oil injection pump for a 1999 Polaris Sport 400. When the atv is running it is shooting oil into the exhaust pipe.

They are gear driven off the cranksahft I have never had one go bad. Maybe the oil pump is not set correctly this I have seen before. Have you just recently installed a throttle cable?

Welcome aboard, maybe it's a oil cooled exhaust? ;-)

96polaris sportsman 400

I scored a piston in my 96polaris sportsman 400.when I removed cyl. and it looked as if this engine was not getting enough oil.this engine has never being ran low on oil.I wanted to check the pump and removed the cover and found the pump broke in half in the middle.I have been unable to find a new pump as Polaris say this pump is no longer available from Polaris parts.My question is the hole to the gear drive off the crank need to be plugged? or can I just replace the cover and seal it all off and premix my fuel.

LDH, They make a cover plate for it, but I just left the pump in there and ran the output to the input. Seems to work fine.
