Installed a new Honda clutch(01 CR250) a couple months ago. No other changes. Basket is perfect. Now starting to die very often at slow speeds with lever pulled in completely. When lever gap is correct it is much worse and lurches. When tightened too much, hoping to achieve disengagement, it still stalls too often. I don't like to run it too tight. Never had a problem like this with this bike in 9.5 years. This is first new clutch. Very, very difficult and tiring to ride a tight woods enduro. HELP!
