I have two 1975 R90/6. I am taking the best parts off of each bike and restoring one and probably part out or sell the other. Anyhow, the bike I am using as the base build has short and flat handlebars on it. Makes for a uncomfortable ride for me. So, I was in the process of taking the taller handlebars from the donor bike and putting them on the build bike. When I tried to install the taller handlebars, they won't work because the cables and wiring are too short.
Does it seem right that these two 1975 bikes would have totally different lengths of cables and wires? As an example, on the left handlebar, the wires coming from the headlight bucket and going to the left grip (turn signals, headlight switch, etc.) measure about 7 inches on the build bike that had the shorter handlebars and the same wire on the donor bike measures about 13 inches.
Any ideas, comments or suggestions?
