Bike wont freewheel when in gear and clutch is engaged and engine not running ? is the clutch broke ?

The clutch is not engaging by the sounds of it ,does the clutch cable have some free play at the lever ?

So if you raise the revs to say about 4000 rpm and let the clutch out does it stall or judder or both will it engage at all and pull away ?

with engine not running rock the bike to and thro whilst trying to engage gear. If it still won't go it's the selector. If it does but will not engage when running it is you clutch so you will need to try any adjustments or change plates.

The starter clutch needs to be replaced. An alternator sgop will usually rebuild these for 1/2 of a new one. Rebu .A thumbs up would be greatly appreciated if this answer is helpful to you.

If the clutch is not engaging you may need to adjust it or it may be deflective. If the clutch is holding enough to cause the engine to rotate when you push the bike in gear it may still not be able to hold when the engine is running.

Clutch not engaging? If you have the bike in gear and engine not running...release the clutch you can still roll the bike? Can you feel proper tension on the clutch lever?

In the past when I adjusted the clutch on my Virago, I would have the bike in gear...with engine off, make sure pulling in the clutch allows the bike to roll..... Then with the engine running I would adjust for the point at which the clutch would begin to engage upon release. Make sure when released, the clutch is fully engaged and isn't slipping.

Sounds like your final drive belt is broke. Put the transmission in low gear with the engine off and try pushing the bike. If you can push the bike with the transmission in gear and the belt is not broke, it could be the front belt pulley is stripped in splined area where it goes on the countershaft. to check that take the rear master cylinder loose and remove the front pulley cover. Put the transmission in low gear with the engine off and push the bike. If the front pulley turns and the countershaft does not, the pulley is stripped.

Good Luck

personally I have never heard of a chain breaking and having any affect on the transmission and shifting. although if the chain broke and caught the shifter, it may have pulled the shifter so hard that it could have bent the shifting forks inside the transmission.. this would explain most of your problems..replace the chain,and with the bike "off" and in neutral, on level ground, rock it back and fourth about 6 inches and try shifting from neutral to 1st and then back up to neutral, and then to 2nd. keep rocking the bike back and fourth while doing this and do this WITHOUT using the clutch. If it wont go to the gears easily, the shift forks are likely bent. there is a safety switch for the kickstand that will shut the bike down if the kickstand is down and bike is in gear. if the kickstand is up and releasing the clutch shuts down the bike, the chain may have damaged that as well. Hope this helps..

Clutch discs are stuck, put the bike in gear, not running, pull in the clutch and push the bike back and forth to break the clutches loose. Once they break loose start the engine put the bike in gear, hold the front brake, and slip the clutch a little to remove any built up or stuck crud on the plates.
