HI, I picked up my first Raider about a week ago. I’ve been in love with these sleds since I first saw my uncles stashed away in his garage nearly twenty years ago. Mine is a 73 and has a Sachs 440 engine retro fitted into it. I’m currently working through the drivetrain and everything looks pretty good really. I’m concerned about the tracks. They are complete with no tears however one of the track shows a decent amount of delamination on the inside. Can I still use these? should I get new? Any idea if anyone has any?? Please let me know I wuld love some advice.
