Raask rearsets were for an RD250, but I fabbed a bracket for them that allowed me to save the original peg mounts. It took lots of trial and error with cardboard mockups to get everything lined up, but they work great.
To clear rearsets with kickstart lever, have to fold up the footpeg. Also had to cut and weld a Yamaha XS 750 kickstart lever to clear the brake pedal, but it works. Was just the excuse I needed to pick up a small arc welder and teach myself to weld! Rear braking was marginal at best, so replaced the original master cylinder (NLA whole or as a rebuild kit) with one from a '90s YZ. Required a modified bracket, extended "plunger" rod.
