My friend's '89 GL1500 has been stood in storage, unridden, for the best part of 2 years. He asked me a few weeks back to take the bike out and to use it as my commuter bike for a while. My normal commuter is my '88 SuperMagna.
I had no problem with this suggestion, but with being off the road for so long, it needed to be checked over for anything that may have stopped working while being unused.
First thing was dodgy front indicators. This turned out to be corrosion on a block connector. dismantle, clean and re-assemble and all is well again.
The front fog/marker lights were out too. This was caused by a faulty relay. Replaced the relay and that issue was fixed.
Next was the inoperative brake lights. Again this was corrosion on the rear brake pedal switch. Cleaned and dry lubricated the switch, a bit of hand operation and it was good to go.
Oil was grand, although it should be changed. Brake fluid appears OK too, but a change should be done soon. Cooling system is tight and leakfree (as far as I could assertain).
My main concern however, is the tyres. The rear is date stamped 1307 while the front is date stamped 4808.
I have mentioned the age of the tyres to him, but he says ''There's plenty of tread left on them yet, they'll be grand''.
Personally, I wouldn't ride on tyres over 5 years old.
A cool day, a bit of wet on the road, a tight bend, a bit too much speed, the notorious spilt diesel on the road, a mixture of any of the above and you're asking for trouble.
What do you guys say?
Change them? Keep them on ('cos there's plenty of tread left)?
How old would be too old for motorcycle tyres?
Check for any stress fractures or fatiguing of the sidewalls. I wouldn't have any problem using 5 year old tires provided they performed correctly. A safe road test will make up your mind on new tires. I am sure there are many of us that have ridden on tires that need replacing that were less than 5 years old:lash:
