To prevent front derailleur chain rub on your bike, you can adjust the derailleur's position and limit screws, ensure proper cable tension, and check for any bent or damaged components that may be causing the issue. Regular maintenance and tuning of your bike's front derailleur can help prevent chain rub and ensure smooth shifting.
Once you reach 100K you're running on or at the limit of life expectancy of the timing chain, chain tension-er, cam chain gear and crankshaft chain gear. All four should be replaced as a set. You will also need to replace timing cover gasket and the crankshaft front cover seal. Cost of parts < $75.00 but not an easy job.
