I know, I know, this issue has been hashed, re-hashed, and re-hashed again! I've been running without a throttle stop on my WR since brand new, but after hearing the stories about the slide plate cracking I'm ready to put the YZ stop in. What is the Yamaha part number for the '99 YZ stop? I've spent the last hour or so doing a search, but have only found info on the later WRs (the only part number I've found is 5JG-14591-00, not the part for my WR). Can anybody help? Thanks!
