Well l purchased a kick lever from a CRF150R for my CR500RE, no good, it is too short; very hard to kick-over, plus the higher compression just caused the swivel joint to stretch and go sloppy after only 10 kicks :-(
I have been using a CR500RG lever as it's a little longer than stock but it still brings my boot too close to the side over, causing it to break :-(
Now l just ordered a 2001 CR250 item to try ...... Will give feedback.
