Nice fit, easy rebuild with all necessary parts.

  Posted:

This is a perfect fit. Much better than the same kit two years ago. On my 78 stock cylinder even felt fits nice. Always a tricky fix - or maybe I am just better. Buy it.

  Posted:

good kit does what it suppose to do. The return spring could be a little stronger.

  Posted:

it's a cheap kit but often the mastercylinder is just worn too much..

  Posted:

Worked well. Does not come with a new circlip though.

  Posted:

got the job the first time

  Posted:

Fast and dependable, also very helpful in the tech area. thanks J&P

  Posted:

perfect fit

  Posted:

Piston was milled wrong. Itwas out of round Had to put old one back in

  Posted:

Worked like a dream needed nothing.

  Posted:

The new piston did not fit into the bore, wouldn't even start. The snap ring is too thick, would not fit into the groove properly. Had to re-use the old parts.

  Posted:

Fits and works just right

  Posted:

very nice kit, although it wouldve been nice if it came with a cover gasket.

  Posted:

gotta have it....

  Posted:

good kit, good price

  Posted:

No problems,looks good and fitted fine.

  Posted:

Worked great!

  Posted:

Spring was way too soft, had to use the old spring.

  Posted:

work great

  Posted:

While the kit picture shows the seal for the cover it was not included. Also the plunger will not fit without modification. Poor quality construction.

  Posted:

compared to the oem part...the spring is not up to par....too weak... needs to be thicker ....also the fiber gasket is thicker than the orignal hd part....

  Posted:

Works great and great price. Everyone is right though the spring is a bit to weak so I had to use the original one as well.

  Posted:

THE SPRING WAS TOO WEAK, THE O-RING WAS TOO TIGHT. I DESTROYED THE CUP TRYING TO TAKE IT BACK APART.

  Posted:

Used this kit on a 1980 Sportster that I rebuilt. Everything was great about the kit except the return spring was a little weaker than the original and wasn't functioning quite right. I used the original spring and everything works great.

  Posted:

Sealing parts worked correctly but return spring was too weak had to use original.

  Posted:

Spring is to weak.

  Posted:

The return spring was not strong enough to push the piston back. I had to use old spring which is much stronger and thicker then the one in the kit. All the other parts in the kit were good.
