I just bought my first TW last night, it's a 92 with 6200 miles. I noticed the throttle run is broken, and I can't seem to find a replacement anywhere. All I can find is 2001-2016 tubes. Any ideas where I can find one that'll fit? Also my throttle sticks open even when it's not being pulled. And it seems like the tube is where it needs to be. Any idea what could cause that? Thanks in advance!
