my bike has 30,000 miles on it. should i start replacing parts like the voltage reg, starter relay and cam sensor etc? or just ride untill they need replacing?

 

...if it's not showing any signs of failure....

I've always thought, if it ain't broke, don't fix it...
or on the other hand, get out there and break something...

 

I don't believe the Evo has very many inherent flaws, but if there is one, it would be the cam bearing. I don't think theres much else thats likely to fail and actually cause any real damage. Upgrade to a Torrington cam bearing and ride it till something gives you trouble. But I would expect that would be a long ways away.

 

mines a 1990 so it already has the torrington in it! but thanks anyway! i guess i get a little paranoid riding this old great bike at times! lol!!

 

1990 didn't come out of the factory with a full complement bearing.

The OEM bearing on my 1998 FXDWG was still going strong at 65,000 miles when I put an EV27 cam and torrington bearing in.

 

Another 1990 here, owned from new. The things that failed early in the life of my bike have not given trouble since. In other words things like stator, ignition sender, gearbox oil seal, cylinder base gaskets, gear-lever return spring, all gave trouble or broke, but I have not had repeat problems since fixing or replacing them.

We just got back from a 2,750 mile trip from the UK to Budapest in Hungary. What gave us a problem? The rear wheel valve stem failed and gave us a flat! A part little more than a year old. Can't plan for that, except keeping roadside recovery up to date!

Ride on....

 

Just make sure your insurance policy has a 24/7 free towing on the policy and ride her till she tells you what she needs.

I second what everyone else said. Also I can't hurt to put a volt meter on it every now and then to make sure you are getting about 14 volts at about 2000 rpms. Just to let you know whe is charging. That is if you are concerned about the charging system.

 

If it ain't broke don't fix it. About the only thing you should keep an eye on in my opinion is wheel bearings. Have them re greased at every tire change. My bike (1995 Heritage) has 119,000 miles on it and it still runs fine.

 

Maybe take a look at the brake pads. Always repack your wheel bearing when you change tires. I always try to make notes in my manual after I do something so I know what I have done. Not that I remember to every time. Keep up on your maintenance. Change them fluids, it pays off in the long run. At 30,000 she's just broke in.
