i got a `99 kx 250 5 days ago and it feels ike its got a plastic clutch cover almost definetely. is that normal? should i replace. also ive never ridden a 2 stroke but when i try to start goin i always stall t like when im letting clutch out and givin it gas i go for a foot i guess then stall? do just give it more gas or what? cant wait to go riding!
