If the problem started after a flush I would definitely re-bleed the system. I personally prefer to use Speed Bleeders.

1998 Suzuki rm 125. Changed clutch lever and when pulled in its not engaging tried to adjust cable in all ways 1/4in play still nothing someone said to pull lever and duct tape it overnight maybe will...

I am sure it's a wet clutch. Pop your bike in neutural. Remove your clutch crank case cover and, using a screwdriver, separate the plates manually. Put the tip of your screwdriver between the edge of the clutch plates and turn the screwdriver. It will break the seal of your plates and spacers. Put it all together again. Do a fluid flush and refill your oil to recommended levels. Get the bike running again and give it a go. Should be fine. Good luck!

2008 Ducati S4RS dry clutch either sticks or doesn't disengage when I pull the clutch in riding, and sometimes I can't get the bike out of gear unless I stalling the motor while in gear.

Check to ensure the hydraulic mechanism is working properly and hasn't leaked. If it has leaked or there is air in the system, it wont allow the clutch to disengage properly and would be akin to a clutch cable being out of adjustment or broken. If the yydraulic release is working as it should be, you may have oil fouled clutch plates. Oil fouled plates would cause the bike to jump/lurch from a stop and could also stick together.

When I shift gears, even from nuteral to first the gears make a hard clunk when they come together. Is this a clutch disk problem??

It could be a clutch problem, if you're disengaging the clutch and holding it for several seconds prior to attempting to shift gears. The gear clusters are heavy enough that, even in an engine oil bath, they'll spin for several seconds after the clutch has been disengaged. Within 10-15 seconds, however, they should be nearly stationary, if the clutch is functioning properly. It can also be aggravated by low viscosity oil in the crankcase; check to make sure that the viscosity of the oil is at least 40W (10W-40, 20W40); sometimes, toward the end of the oil's service life, it can suffer a significant loss in viscosity. If keeping the clutch disengaged longer doesn't minimize the grinding, flush the clutch hydraulic line; if that doesn't work, the clutch assembly will have to be removed and examined for bent or buckled diaphragm spring, pressure plate or clutch disks.

To flush the clutch hydraulic line, remove the left (shift lever side) rear cylinder cover (3 cap screws, 8mm Allen). Beneath the cover at the bottom, you'll see a neoprene "trapdoor"; that covers the drain fitting for the hydraulic clutch assembly. Loosen the fitting, slide a flexible tube over the fitting to route the old fluid to a pan or jar (you really DON'T want the old hydraulic fluid floating around under the cover), and pump the clutch lever, periodically refilling the reservoir on the handlebars, until the fluid coming out the drain is clear and free of bubbles. Remove the flexible tubing, tighten the drain fitting, and recheck clutch operation and gear noise when shifting.

If flushing the clutch hydraulic line does not quiet shifts, I would have to recommend purchase of any one of a number of good maintenance manuals to facilitate removing and inspecting the clutch "pack", the illustrations make a very difficult-to-read procedure quite straightforward.

Clutch slippage

Drain fluid out of clutch cylinder. Clean out cylinder then look at bottom and you will see 2 small holes.Stick a small pin or wire into the hole that has a little check ball inside. Once you can push that ball in with the pin you will see some fluid come into the reservoir. That lets you know it was clogged. Now refill with dot 4 and bleed system. Clutch will not slip now. I just had the same problem and changed clutch spring, plates, etc and nothing worked until I did this.

When i pull the clutch on my dirt bike it doesn't spring back and when it's pulled the clutch doesn't engage.

First, get a new clutch cable. Tape the new cable to the old one and unhook the old one. Now you have a new cable and a reserve cable ready for use if needed during a race.

Second, change gearbox oil and install a new oil filter if your bike has one. All the dirt and grit in the oil is binding the clutch. Ride the bike for a couple of hours using the clutch often. Now drain the oil again and put in fresh oil. This will flush out the dirt and grit. Use 10w40 motor oil. Stick with the major brands; Pennzoil, Quaker State, Mobil or Shell.

Repsol MOTO Gasoline Motor OIl,4T,Sintetico synthetic blend 10W40

Repsol Moto 4T Sintetico Synthetic Oil - 10W40

Synthetic blend lubricant with high thermal stability, designed to meet the needs of the most technologically advanced 4-stroke motorcycle engines.
  • Excellent starting and lubrication in cold conditions due to its low viscosity.
  • Meets JASO MA API SJ requirements.
Its fine to change your oil with synthetic, Just be sure that you use synthetic from now on... I don't think its advisable to switch back to regular oil after using synthetic.

When i accelerate hard on my cx500 eurosport the clutch goes solid and i cannot change gear until i slow down ,any ideas ?

Change the oil and oil filter. Ride the bike for 50 miles or so then change th oil again but w/o another filter. Dirt and grit in the oil is making the clutch grab and not fully disengage. Changing oil will flush the gearbox. 10w40 motor oil.

Please rate this solution. Thanks bloohart!

Jumping about in first gear

Sounds like time for an oil change. Dirty, gritty oil is causing the clutch plates to grab. Change the oil filter along with the oil. Ride the bike a hundred miles or so then change the oil again. No new filter this time. Doing this should flush out the dirty oil.

The bike is 10 years old. It is probably time, (or past time), to replace the clutch cable. Most cables never seem to get lubricated. The oil and the cable are low cost items and you can't go wrong in doing the service.

Please rate this solution. Thanks Tony!
