Most carb problems happen when the bike sits. If things are running really poorly you need to clean out your carbs. There should be a fuel/air mixture screw. That's pretty much the only adjustment you'll need for tuning. Your best bet is to find a guide for your bike. The end game is to have your spark plug tan coloured. If not enough gas is getting through you will have white spark plugs, If too much gets through you'll have black plugs. Oil can cause blackness too. There is also an adjustment for idle. You can adjust an idle stopper so that the throttle returns to 1000rpm or 2000rpm when you let go. (I think most should be set just over 1000rpm)

For the more technical parts of how a carb works; There is a slow jet that allows gas through when the bike idles. At full throttle the main jet will be supplying most of the gas. In between it will slowly transition. The fuel screw adjusts the opening in the fuel line. (sort of)

The reason one carb is handy for maintenance is; To tune most 1970's Honda fours for example you need to set the timing, then valve clearances(otherwise you could tune to accommodate improper settings), then you set your fuel mixture on each carb, Then you have to hook up 4 vacuum gauges to each of the 4 carbs and adjust the setting on each carb slide so you have identical vacuum readings at idle, half throttle, then full. One carb doesn't need this last step.

I learned the most from reading clymers and hanes manuals. Definitely worth picking up. Just read through once or twice before you dig into anything. Some instructions are unclear or they tell you how to take something apart and then say "do the reverse to assemble"

Well, may as well post my Honda cb650.(I tried but i'm too lazy/stupid to upload a picture) My bike has developed a total loss oiling system too. So far I've rebuilt the carbs, head, front brake, swapped the alloy wheels for spokes, lowered gauges and headlight, added windshield. This past year I picked up a Triumph Trophy 1200. It's a great bike but rides aren't the same with a full fairing and quiet exhaust.

I second the savage being a good choice. Carb kits add up when maintenance time comes round. Then there is syncing the carbs (if there is more than one). ...although I still dream of getting a honda cbx with a 6 cylinder engine...

Hopefully the picture works^^. Just got a 1979 cb650 a few months back. Needed a bit of work, had been sitting for 3 years.

Since that picture it has had a new seat, new battery, front brake completely pulled apart and rebuilt(It was full of brake sludge, didn't work), new carb boots, carbs rebuilt and declogged, valves adjusted, carbs synced, tank cleaned, Ignition and seat lock fixed, new tires (shop put these on), new chain.

Hopefully by the end of summer I'll have new fork seals, shifter peg seal, and a custom seat I'm building from the pictured OG seat pan/foam. Seat will be close to original just slightly flatter and with 2.5" ribs across (if that makes any sense...)

Long term goals include exhaust headers that aren't rusting out, a paint job not inspired by orange peels, maybe pods, maybe removing side covers.

Built up my new-to-me late-90s Norco Rampage. I can ride XC again!

Rabbit truck? My friend had one of those. People always left notes on it in parking lots, trying to buy it. His didn't have any rust though...
