Fork seals gone on honda nsr 125
280 ml on the older models, and 320ml on the newer models.
1. you need to elevate the bike with a jack or something so the front wheel is off the ground.
2. undo the Allen bolt on the side of the fork, then proceed to take the main wheel socket bolt/bar out, so the the wheel comes off, the speedo drive will come off leave that hanging around lol.
3. take of the socket bolts attaching the brake caliper to the fork, dont leave it hanging secure it somewhere, so you dont damage the brake cable tube.
4.take handle bars off, one allen bolt on each one.
5. then unscrew the the 2 socket bolts that hold the folks on, if you follow the folks down you will see 2 socket bolts take them out. do the same on other folk.
6.then pull one folk at a time down, maybe tap it if its hard. and you will have the folk out in your hands.
7.unscrew the big socket bolt at the top of the folk out, but apply pressure, sometimes the bolt will fly off, so be careful.
8. take the big long plastic tube out along with the spring, and tip the folk upside down and pump it to get most of the oil out.
9.then go to the bottom of the folk and undo the allen bolt, when its moving around freely and not coming out put the spring in and push down and twist the allen bolt should come straight out.
10.pump it a few times and then you take the folk tube out completely and give everything a clean, it will be stiff when you get it near the top so get momentum and yank hard and it will pop out.
11. then the bottom pit of the folk that the tube goes into, if you look into it you will see the oil seal, take the cur-clip out and it should come out pretty easily.
12 give the folk tubes a rub down with fine sandpaper say 1000 grain or 800 grain, to get rid of little bumps, look carefully feel it with your hand, to see if theres any pitting, you will be able to see it, thats not good but make sure its not on the part of the tube which goes up and down the oil seal when compressed down.
13.put folk tube back in the bottom of the folk, then put spring in puch down tighten allen bolt.
14.put new oil seal on and push it down its best to use a oil seal hammer tool thingy, but if your careful you can tap it down with a hammer and something small and flat at the bottom, i used a bolt, worked well.
careful dont damage the oil seal.
15. put cur -clip back in, it should click, make sure its on the closest ridge to the oil seal.
16. put 280 ml, of oil or if you have a newer model 320ml, of fork oil in the tube, pump it a few times to get air out and oil to the bottom chamber.
17. put the spring back in and the long plastic tube, and put the top bolt on for now not to lose not to tight.
18. attach the folk to the bike again and same with the other one, make sure you align the little ridge on the top of the folk, with the top of the steering bar, the top steering the bar the folk go into last. its late lol getting confused lol. oh and when y0ou align make sure you tighten the bolts holding the folk in place.
19.then put the steering grips/bars back on and then tighten the top bolt tight cant remember the torque setting. then you know everythign from there. phew
