Bike sat for two years didnt have the problem before tried adjusting it to no avail it is not fully locked up when I apply the rear brake the bike will stop but the idle will lower showing theres still some resistance and bike will not shift unless its up on the stand with the rear wheel off the ground should I pull the clutch out maybe it just needs cleaning dont want to spend money on it since my unemployment ran out just want to sell it it has 15000 miles on it thanks
