Something like a car, get past a certain mileage/Kms and nobody wants to buy it, or you get pittance for it. Motorcycle the same. I've asked many who make this type of comment if they wanted me to buy the vehicle and not drive it.At that many miles they will still run great, but you about have to give it away to get rid of it. Little repair jobs can get to be expensive. Just have to decide how much time and money you want to keep putting into it. I gave my 1500 away at 235K because it wasn`t cost effective to fix anymore. Wanted a 1800 anyway.
My old 1500 still purred like a kitten, BUT once the drive shaft splines stripped out, the fairing was cracked by the 2 screws that hold front of fairing on, the bike would quit running at the slightest rain fall, turn signal switch needing replacing, 4 way flasher switch likewise, and it needed a rear cubby hole door. Still looked good enough some people that didn`t know better asked if it was a new bike. But it had 235K miles.
Or older, my '85 has 66K on it and runs like it. ALL of the factory maintenance is done and EVERY bearing and spline has fresh grease. The '81 will have 53K on it and have the same maintenance standard. I will not live long enough to wear these bikes out.there comes a point when you have to ask yourself,
what is it you really want to do?
Keep fighting the good fight, or just trade it off and get something newer.
