I would bet they be's rusted up so solid and stuck or's rust pitted deep as the Grand Canyon
I had a lot of fun riding the 200SX , it is so easy to maneuver , lots of power , light weight , was super reliable for me and the ones I had were put thru HELL , mostly by family members and friends who were trying to keep up with 300's thru the mud ----the only problems I had with them was the chain slack and wear from running the chain in slop , they are a bit small , limited tire size and finding parts
I like that engine so much , I have a 86 200SX engine /wiring harness that has been rejugged , ran one time on the table and ready to go into a cart one day , last week I was playing around with the project , a 82 Club Car DS golf cart , with a swing arm , live axle rear end , chain driven , jack shafted , 5 forward , 1 reverse , automatic , electric and pull start 200SX engine , it could be fun[/QUOT
I think its just the seals, honestly I haven't removed them, just got them moving a bit,an bleed brakes several times, they are not leaking, but just don't seem to hold pressure. I will go a little further into them after reading these comments,an see if I can source the rubber seals, lot of the other models in this year range look like they may work,but not will to just order $30 rebuild for one side with just a gamble of they look like they fit.
