Oh the horror...........I went out by the motorcycle and saw what looked like a tiny drop of water on the floor next to the bike near (under) the left grip. Well it wasn't water it was clutch fluid. So I looked and couldn't really see any signs of leaking until I got the flashlight out. Yep, wet at the plunger and bushing!! Took it all apart and cleaned everything. Back together and actuated the clutch many times, could not produce any amount of oil so this is a very slow leak.
So, I have on order the guts from the spring to the plunger from HDL, parts on the way.
My question is to those that have been here before. I'm not worried about the removal or installation of the master cylinder itself and bleeding. I am however wondering how much a PITA changing out the guts is going to be. Is there any secrets I need to know?
TIA for any information!
23 years old and 173,000 miles. I wish these parts lasted a bit longer. LOL

No, it's pretty simple and straightforward.  Thanks, so a generic snap ring pliers like I use on the drive shaft should work? The Honda manual has a special tool (of course) listed but it says its a snap ring pliers. |

Next question. Can I empty the master cylinder and change out these parts without removing the master cylinder from the bike?

Yes. Done it on a number of Hondas that use this master cylinder. As pointed out above, good set of snap ring pliers and away you go. Make sure to protect your paint from any residual fluid that escapes, and I'd suggest vacuuming it out at the slave cylinder bleeder before beginning work at the handlebar. |

I've only done it from a bench. Too much chance of scratching, spilling, losing parts for this old man. |

I remove it from the bike so I can clean it out real well with brake cleaner. I also run a hone in and out a couple of times. I make sure the two ports are open and clean. The job is not bad. The most frustrating part is the snap ring, but you will be able to get it. I do chuck it up in my bench vice using padding in the jaws when I do the snap ring. It is easier if you push the plunger down a bit with one hand and put the snap ring with the other. One beer job. Check YouTube for a Brakecrafters video. They show it really well.

Ok, I have a final resolution to report. Another VRCC member Farside came over to help. And I m glad he was there. I did not remove the master cylinder from the main hydraulic line so having a set of hands to steady the master and also to hold the flashlight at times made all the difference.
The hardest part was getting the circlip out because my circlip pliers wouldn’t reach in far enough. I had to grind the nose pieces to extend their reach. Once we figured that out it went real fast.
Oh ya if you buy the set from Honda the oil seal comes not installed on the main piston and that’s a tough installation lots of stretching and prying being careful not go break or damage the seal.
The end result is a fabulous feeling clutch. It now engages significantly earlier and smoother. Slow speed control is way better and smoothness in the lever is back like new. And!!!! No leaking.
The whole thing cost a bit under 100 bucks

Working on the same job, just finding it easier to take it to the bench..... I bought m/c circlip pliers from Amazon -- $18 bucks and was ok.... Getting the oil seal on the main piston is a royal PIA! --- I tore one seal and had to reorder a 2nd kit... Havent attacked it a 2nd time, but gonna figure out something to get it to go smooth.... |

I didn’t think to use some oil. But not sure it would make it easier or harder. It’s stretching the seal that is the hard trick. All slick with oil may not be helpful

I did drop some fluid on it, it does slide on the shaft easy enough, but then its too slick to grab and pull over the area it supposed to go. I tore it good while fooling with a screw driver.... And you cant just buy another seal solo.... bleah |
