Go to your nearest bike shop that carries dirt bike accessories. Get a fuel cap silicone vent line. Swap it in place of the stock vacuum line. It will hold up to the radiant heat off the back of the engine much better/longer than the stock line does.
Go to the nearest "tuner" car shop with your fuel line and get a silicone replacement for the same reason, plus the fact that the stock "fuel" line is actually a chunk of vacuum hose...
Inline fuel filter is a must. I prefer the metal type with a porous bronze "stone" over a generic paper or plastic cored throw away type. If you want a throwaway type, get one suitable for 69-71 Dodge trucks with a 318. Huge, but it works very well. I get a few months at a time out of one on a truck with a rusty gas tank. The filter is available for 1/4, 5/16 and 3/8 fuel lines.
On the old forum we had two very memorable Savage failures... one snapped the con rod at 178K miles and change... the other one grenaded the engine at a touch over 200K miles... and they were both the early 4 speed type.
My odometer quit working years ago at 15K and change showing. The engine/transmission are flawless, the electrical system failed in 2010. The bike is a 1998 model that was already ridden hard. Good oil, decent filters, proper belt tension (tool sets them too tight), properly inflated tires for YOUR weight and riding style, making the bike fit you, etc are critical to getting a long service life out of them. Bikes over 500cc have a rated service life of 5 years or 15K miles... the 1500 Drifter is going to roll 90K in the next couple weeks or so... it was purchased in 2007 with 1600 miles on it, it's a 1999 model. Will likely need a clutch at 100K or so. My friend actually rode it from WA to TN in 2011 when he moved, and he does not own a four wheeled vehicle.
Subaru Outback? EJ22 engine is nearly indestructible, the EJ25 and the 6 cylinder versions, not so much... We've got a first year with an EJ22 and an automatic transmission sitting in the driveway. It's last real trip was Memphis to Nashville and back. 226K miles or so and it was done. Body metal is flawless, powertrain doesn't want to play anymore. Not throwing any codes, pretty sure the ecu decided to tell us "F U"...
