Question about 2003 Yamaha Road Star Warrior
Backfiring and cutting out liike this is probably a symptom of one or both of the following: too rich a fuel mixture, or too weak a spark. Take your spark plugs and see if they tips look tan or black. If black, your fuel mixture needs to be leaned out. Another possible cause is a dirty and or clooged air filter, which can reduce the air flow into the engine. Take it out, bang the dust and debris out. If it looks really dirty, replace it -- they're cheap. If your spark is too weak, you may also notice a loss of power, especially at higher revs. If none of these seem to be the culprit, have your ignition timing checked.

all bike are to be checked in the upright position! then find out how much the bike takes from your manual if you dont have a manual ...do the following ..when you just change oil and not filter you will be adding less oil,"almost" all bikes take @ 3 quarts oil minimum, so what i do to be safe!! is always after draining is put in two quarts no problem, but with the third bottle i only pour in half.. drop oil cap back on and start the bike and let it run for a minute, the turn it back off, then check oil level, if it doesn't register anything on the stick or sight glass then your o.k. to add the rest. now take a reading, and only fill to almost full, i always under fill my bikes, because over filling will cause damage to internal bearing by the air bubbles from the splashing of the crank in the oil pan. Same as cars.
If you found this helpful can i get a rating?

You can adjust it by slackening the cable...unless it has hydraulic operation....Otherwise get it replaced before you do more damage..ie clutch dust and debris in the oil, so dont forget the oil and filter change too.

gear selector may be jammed inside the casing or broken
check that the shifter is tight on the shaft!
check clutch adjustment
try rocking bike back n forth without using clutch while you try ******* the gear lever it may come unstuck
but get it looked at if it frees up!

Does the bike have a sidestand switch that cuts the power if the stand is left down? If it does, disconnect it and temporarily join the ends together and try starting....

sounds like fuel starvation
do you have a petcock plugging or a dirty carb?
pull the fuel line and check flow
