I have just done a lot of work on a couple of these Red.....have a good look at the frame around the top shock mounts, the lower frame rails and all the welds in general.....rust and cracking is common. The rear brake pedal pivot is usually got lots of play in it....make up a new bush for the frame and a new pivot pin. The swingarm bushes are another headache....we just made up new phosfer bronze bushes and hardened steel sleeves and fitted hardened steel shims for the clearance. You goona need a mate with a lathe
. The rear brake torque arm is a shit set up as well....cut the lug off the frame, weld a 10mm bolt/stud in place, get a 85 KX125 brake arm, mod the rear angle where it fits the backing plate and you will have a trick looking rear brake arm (alloy with lots of slots in it). Another lathe job is the rear brake backing plate....make a new phosfer bronze bush there and check the little brake cams in the backing plates for play as well....you may have to re-make them. Cool bikes that are made on the light weight side of things and wear out through neglect but worth doing. Really nice bikes to ride.
