Bike jumps and stalls

Hi gonna explain the problem an the fix.Take it to a very good motorcycle shop tell them you want the clutch changed the clutch cable changed and a full tune -up oil an the works let them know the clutch was grabbing.It will be fixed it sounds like the clutch plates might be warped an grabbing not an adjustment issue the plates aren't releasing inside the engine and are locking up. ......Good Luck hope this helped old bike mech :-)

See if you can push the bike with it in gear and the clutch lever pulled in. If the clutch is stuck, push start the bike, jump on, get to about 10 mph, pull in the clutch lever and hit the rear brake hard. This will usually break a stuck clutch loose.

Get car oil out - friction reducing properties ruin wet clutches - put bike oil in
Make sure cable is adjusted properly
Plates may get stuck together after time unused - see my tip for quickly releasing seized clutches

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.

these bikes run on wet clutch plates the grade of oil must not be the right on if the oil is ok then there must be a problem with the oil pump not working once it gets hot

hi mate try not to use fully synthetic oil use semi synthetic and if its clutch slipping you will tell because when you put it in 1st gear it will jump forward or move a little bit but if not then your clutch is perfect also check chain tension if to tight will cause clunking good luck buddy :)

this may help,it doesnt sound like the clutch is out of adjustment,it sounds like the clutch plates have become stuck together,(this happens quite a bit if the bike has been parked for a while..ie over winter)..to fix it get the bike moving,down a drive way or something..then just bang it into gear,then shift into the highest gear you can by shifting without the clutch,once you have a bit of pace on simply hold the clutch lever in and work the throttle on and off all the while holding the clutch lever in,the clutch should free itself fairly quickly and should be back to normall,a lot of older bikes are good at doing this..hope this helps

Did you do an oil change recently? Sometimes a motor cycles clutch shares the oil with the engine and a different kind of oil then the bike requires will cause the clutch to slip. This happens alot especially if someone switches to some types of synthetic oil when the bike had regular oil before the oil change.

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!

1) Can you push the bike while it's in gear with the clutch pulled in? [If so, clutch is disengaging OK]

2) If not, check when you pull in the clutch lever that it pulls all the way through to the actual clutch [If not, replace broken clutch cable]

3) If so, clutch is binding. Either fix it properly by stripping the clutch.. or just brute-force the plates apart. :-)

Brute-force clutch plate separation: First make sure you have enough oil in the engine (wet clutch), then basically you're looking at either riding it with the clutch lever pulled in until the plates come apart or with the rear wheel in the air CAREFULLY running it in first gear against the rear brake while the clutch is pulled in.
