Been using them on the latemodels the past couple of years and this was the first year for the modified.

Like them, every 4 nights prop the rearend up on jackstands and unhook both the top and bottom bar (4 link) or swingarm and rear bar (Z Link) and spin the birdcage to keep everything lubed up and keep the grease from settling in the bottom.

You cant just change them out for the nylon liners. You would have to get birdcages made for them or machine yours to accept the bearings if possible. Several places make a good bearing cage, BSB, PPM, TWM etc. We run the PPM bearing cages and they are great no complaints at all.

The problem with the nylon is the grease attracts dirt and then it starts to wear into the housing. Plus as the housing gets hot during racing I think it makes the nylon swell and if you dont have enough clearance they start to bind up.
