I put a new starter in my '03 WR450 with the '04 upgrades (old one died). The starter is spinning fine, but it doesn't seem to be engaging, or should i say turning the engine over. Sometimes it will catch and it sounds as it should, and the bike fires up. Other times you hit the button and release quickly and you get nothing, nothing nothing and it catches and then nothing. ***! Is there any way i could have put it back together wrong or missed something? I'm pretty sure this isn't the case.The kickstart still gets her going but the button would be nice to use again. Cheers Chris.
