thank you sirYes, it could be made to work if you have all the parts. They are basically the same bike.

There is a rear foot brake kit available.
Major issue....The 1987 foot brake is mounted on the Kickstarter shaft. (see pic). I think the 1986 has a cover over the shaft which could create a major issue because the shaft doesn't protrude past the cover. Engine has to be taken apart.thank you sir
