Just replaced my Swing arm Zerks. The old ones did not work so well and i would like to keep the swingarm lubed.
Rip out the old nipple with pliers.
Im going to use a 6mm zerk nipple i picked up at Oreillys. I used 6mm because i already had a metric tap and since its a metric bike why switch. I also like to measure how deep im drilling it out.
After you drill it....You tap it!
Clean out the shavings as much as possible. Thread in your new zerk/nipple
Give it a squirt to clear out any shavings and old grease, then slap it back on the bike.
