I was going to rebuild my trailboss master cylinder/handle/whole assembly(w/e), after trying to get it apart, a few other things not right, i decided im gonna just buy one off ebay.

is showing that they will fit my 1997 trailboss, but do others? Would help to be able to widen my search.

Basically, is the brake line fitting the same size as the rest?

 

Most of the master cylinder problems are because of worn piston seal or sucking air from a worn seal under the reservoir. Item#9 and 17.Dirt Cheap Yamaha, Honda, Arctic Cat & Polaris OEM Parts & Accessories – Cycle Parts Warehouse
Most other Polaris models will interchange,can't speak for a universal one as some threads may be metric others standard.http://www.ebay.com/itm/POLARIS-ATV-MASTER-CYLINDER-PISTON-SPRING-SEAL-5020671-7041311-3610022-56-89-/301084014232?pt=Motors_ATV_Parts_Accessories&hash=item461a017698&vxp=mtr

 

I just found one that looks identical to mine on ebay. A few hours of searching, found one with OBO and saved about 25$.

Now I just need to swap my drive sprocket out so i can run my 25" tires. I've read that the stock sprocket has 14t and I need one with maybe 12 or 11. I would imagine a 250 would bog going uphill with 25x10x12s

 

Just looked at a few diagrams for the 97 trail boss. Appearently the stock tooth count is 12. So will I need to change anything out for 25" tires? They are the stock dunlops from a 2011-2012 ranger. I am ordering some 12x7 4/4 rear wheels.
