That brake fluid should be replaced.
Valves adjusted.
No reason to inspect hoses, just replace all both of em.
It's too cheap to hassle with trying to decide if they should be replaced. They are old, grab some fresh. If the belt looks good & it stays outta the sun, it's most likely okay.Besides, it's not like you will be caught a hundred miles from home if it poops out.

Since you ride so little, maybe having the work done would be more cost effective than learning.
IF you want to learn it, I will help all I can. Get a manual & tools. It's really easy.
If you are interested, we can discuss what tools you just have to have to do this level of maintenace/

One of the great things about the Savage is how simple the MC is. Yeah it would be nice to have all the whistles and buzzers, but if you don't have them it simplifies things immensely.

I would say wait until the normal maintenance interval. Why is the dealer recommending a tune up now? If you are going to have the dealer do the maintenance, are they offering a discount to do the work now. (Enough of a discount to justify doing some of the maintenance a year or two early (based on riding less than 1,000 miles per year). Incidently some things should be done on a maximum time interval regardless of how many miles you ride.

Are the valves so clattery you are worried? How long since they were adjusted( in Miles)?
The Floof on shutdown is desireable, not something to repair.
Is the plug gone oin the right side of the carb? I mean, Has the pilot screw been adjusted? I am guessing either you are at a great elevation for the stock jets to work or someone has rejetted it. Whats your elevation?
For $250.00 they could well do plenty on it. I expect they have listened & know darn well the valves are okay. They are supposed to make a bit of a clackey sound.They wont replace the belt for that $250.00. I expect your money will buy you a brake flush & 2 hoses & a new spark plug & oil change. YIP sceamin PEEE!! Or, is this to repair the leak, too? I would let them fix the leak & do the rest yourself. It's okay to start on it & finish it a few days later. Get a tarp & cover it if it's an outsider. Oh, park it on one too, so you can find stuff when it falls between fingers.

yeah it is not the fuel hose, that is what I thought it was at first but the whole petcock is soaked in fuel and the weird thing is it only leaks when the bike is leaned over on its kick stand. I am going to hold off on the tune up until I hit 11,000 miles. I can change the fluid and brake lines myself in the meantime. I am just waiting on them you call me to tell me what the fuel leak is.  As for the backfire after shut off it is not very loud. and the valves are not clattering. The bike is just so perfect and un-abused that I didn't want to put something off that needed to be done. As for the altitude, I bought the bike in Northern C.A in the foothills and it backfired after shut off up there as well. Now the bike is living in San Diego. So I just assumed that the altitude had something to do with it. I am still not sure how long I will keep it though. I am about a half inch short of 6 feet tall so the bike is a little cramped. I think I might switch to a ninja 250. we'll see though
