Whats different between the 86-87 and 88-89 frames? Seems like allot of parts are the same.

I am not sure of all the differences,but here is what I know.

Where the swinger bolts on is completely different.88-89 had a soild tube swinger at the pivot area.So you have to use a 88=89 frame and swinger together..The 88-89 swingers were aluminum and shorter than the 86-87.The rear motor mount bolts directly to the frame on the 88-89,where the 86 motor had a added bracket that the swinger bolt passed thru the motor.

The 88-89 frames were made stronger,with better gussets.

The 88-89 had a different steering stem,with no headlight mounts.The 86 -87 steering stem had extra mounts on the stem to mount the headlight.If I remember correctly,the rear shock linkage was different too form 86-87 to 88-89,but I dont recall the specifics.

With the exception of the swingers,just about all parts interchange.

EDIT>>>>
The 86-87 also used a different grab bar with farther mount hole spacing.The 88-89 used a grab bar with closer hole spacing.
