2003 ec250 clutch issue
After running fine the clutch on my sons bike would not dissengage. I bled the hydraulic clutch which did seem to have air in it, but the bleeding did not resolve the issue----that being that even if the clutch lever is pulled in the clutch is still engaged.
Can anyone provide me a shortcut on what to do? Thx, Mike |

Does the clutch lever feel like it did before, like it should be working? Or is it limp like there is air in the system?

Did this happen after the bike sat for a while? If so mine did the same thing so I put it in neutral and push started it then once the engine was running the clutch freed up and worked like normal. I'm not sure why this happens sometimes maybe someone can chime in with a reason.

Bike had not been sitting, lever feels good, especially after bleed.
will try pushing bike, and rocking it---but I think the issue is that the push rod that opens the clutch plates is not activating, and thus the clutch is always engaged. I'm thinking the hydraulic clutch mechanism is broke. Every other street and dirt bike I have has a cable |

The clutch on my new to me 03 EC250 drags bad also...at the lever feels pretty normal although maybe stiffer than a Husky or KTM....drags just enough to kill it when you put it into gear....mine is overfilled with tranny fluid so I am going to start there and also have a little moisture at the lower clutch hose joint...so a few brass washers there...mybe all that will help....

Search for my thread, on my EC250 one of the nuts in the the clutch assembly came loose and had to be tightened.

Yesterday, tore out basket and plates were stuck together pretty hard. Prior owner's fluid was thin and redish, not bad looking for solids. Plates had some wear, but not bad. No warpage or burning.
Took apart and reassembled plates used Shell Rotella 15/40 full synthetic for lube. Tested the clutch actuator and it worked fine. Reassembled and have slight improvement---if in gear and not running, pulling the clutch lever does not let the clutch loose. You have to put it in neutral to start it. Once running, the clutch does dissengage the drive enough to stop in gear, but seems to drag a bit. Once I put a new clutch pack in an RM250 and I had a similar issue, but I thought that was just because the new cork and steel plates were toward the thick range of spec. Any ideas? |

Basically a bad dragging clutch is from inadequate drive/driven plate clearance from one or more sets of plates at any one measured point, or overall pressure plate travel.
Are you sure that it IS bled completely? Lever adjusted correctly, especially when bleeding? Master/slave free of internal leaks, that is when lever is held in does pressure plate creep back to engagement from spring pressure? Basket notched severely? Loose basket like Sideshow noted? Rubber shock dampers in basket intact (basket not moving around on ring gear)? Sounds like the bike had some type of ATF in it. My son's KX85 had the clutch pack stick tight after sitting like this for a short time. Rotella should be good when the main problem is solved. |

bleed it alot of times so no air, maybe the seals in the MC is letting the pressure bypass? I haver no visible external leaks. and i'm not loosing oil from the system? Is it just a new sealkit for MC & SC that I need?
