400 2 stroke bebuild?
I have a buddy who has a 95 Polaris 400 that just won't run right anymore. I told him I would take a look at it but don'tknow where to start. I was told that NO maintenance was performed since it was new. So I am guessing a top-end rebuild , carb kit, checking all fuel lines and such. Any advice would be appreiciated guys.

I would start simply by looking at the sparkplug. My 400 2 stroke fouled one every once in awhile. Carb rebuilt would probably be my next step, unless you know what your compression should be and do that check first. My 400 was trouble free so I really couldnt give any other advice. Please let us know what you find. Good luck!
I assume when you mentioned oil changes, you were refering to the drive systems????

That old of a 400 will most likely need top end rebuild. You can do a compression check to make sure. If compression is low it wont run. Piston, rings, head gasket and hone or bore will do the trick. Then clean the carb while its off. You can get some good trouble free years out of the motors but they all will need top end work at some point.

Maybe I should have been clearer.
