I just got a 98 Polaris Sport/Scrambler 400 2X4 that is missing the front master cylinder. My local dealer wants $119 for it. Are there any replacements for cheaper? Anyone have a used one? I searched and found some threads here about a replacement that changes the side where the cylinder is located, and I do not think I want to do that....

Thanks!

Hey check ebay, there is always scrambler and sport parts. I think any polaris master cylender will work.

 

You can adapt a 400ex master cylinder which is cheaper when bought new, but it will be on your throttle. Unless you get luck on ebay, your choices are limited.

 

If you do buy new I would try to update to the 2001 model or newer. Much better unit. I believe it will bolt right on.

 

Do like Bubba said, update to a 2001, you can also change over to the braided lines at that time, and really improve your stopping ability.

400FN, who's doin' the chromoly frame for you? Any price available?

I have a long time friend who is a welder, and is good at it. But right now he is in Virginia on a job. He is supposed to be in soon, and he has no idea what I have in store, but if he is willing to tackle the job, I'm willing to dish out the dough. But if he can't do cromolly, I have a welder here locally who can weld aluminum, so I may go that route if the chromolly can't be done. Another friend of mine who is in college and studying to be a mechanical engineer already has a 250r frame modified to fit a 400 motor drawn up on AutoCAD, and we may build a frame out of regular steel tubing first just to make sure everything is drawn up the way we need it. More like a test unit than anything. Either way, I will have a lighter and better frame.

 

If I put a 2001 master cylinder on it, will I have to upgrade the hoses then, or will it fit without upgrading right now?

Thanks!
