try this remove the clutch arm cover, remove the clutch arm and see if the arm moves on the rod it is attached to. if it does try tightening up the nut on top of it. if that does not work you might have to get a new arm or you can get a small screw and screw it in between the two pieces or drill a small hole in between the two and do the same thing. if you do not have the resources Manic Mechanic from creative engineering has a web site and he sells custom clutch arm assembly's, if you do not want to try to fix the arm.

hmm loosen up the flower nut then try tightening up the inner clutch spring (so you can get more travel in the clutch) then try to disengage the clutch again.

question with the pin in (what the arm moves) how much of it sticking out 1/4'in ?

i just reread and have a question the where the clutch pin in is take it out and turn your motor to see if their is a little bearing the same diameter of the pin you might need a magnet to get it out, if their is no bearing you will need to get one. If their is one put the bearing back in put a little grease in the hole first and the pin. proceed below

Ok take the clutch arm cover off again,

in that picture the position of the clutch arm. If the arm looks like that and your clutch is not disengaged you need to tighten up the inner spring some more try a full revolution, take the flower nut off this time so that you can get a good turn on it. if you cannot tighten it up anymore with the flower nut off skip this step.

leave the cover for the flower nut off for the time being.

when you put the clutch arm cover on line up the flat spot on the clutch arm so that it meets with the clutch pin.

now disengage the clutch and engauge the clutch a few times, while you are doing that look where the flower nut goes you should be seeing movement of the center rod where the flower nut goes.

while you have the flower nut off this would be a good time to clean the clutch pads, take off the clutch wheel the sliver one that is just a plate and look at the inside where the clutch pads meet the plate. is the plate shinny if so get a flat file and file it flat all around the surface to roughenit up, if you have some brake cleaner around spray some on the friction pads and let it dry.

if you can see a good amount of movement I'd say about 3/8 of an inch you can put the flower nut back on leave the little screw off that holds the position of the flower nut. do not wrench the flower nut on pull the clutch in and tighten it up a little,

try starting your bike now, if you cannot disengage the clutch tighten up the nut a little more and try again. after you find a point that the motor can start tighten the flower nut a 1/4 turn and reassemble.

good luck

wait a minute your clutch arm? is the flat spot on the arm lined up with the pin flat?
if it is you will need to use a hammer or some tool to knock off the arm from the rod and reposition it so that it is running inline with the motor. pic below. I have mine off set a little bit.
if it is out of alignment reset it get a perm marker and mark a point on the clutch arm and the nut in a line so that you can see if you pull in the clutch and the arm is slipping on the rod and let me know.






question with the pin in (what the arm moves) how much of it sticking out 1/4'in ?

so their is no movement of the threaded stud that the flower nut is on when you pull the clutch handle in? when you pull the handle in the flower nut and clutch plate should move out.

can you take some pictures for me. the first one with the clutch arm cover off that shows me how much the clutch pin is sticking out (looking side ways the like trying to look down the chain), the second one of the clutch plate with the flower nut on normal clutch position and one when you pull the clutch in. (push the clutch arm with your hand all the way as far as it will let you)

we will get to the solution of this problem dont stress out we need to go over stuff till we find it. i all ready have my next question if the pics cannot help out and if the clutch arm is in the wrong position.
if the arm is slipping you will need to do a little work to fix it dont worry it's an easy fix.
