  • 01 xv16 road star starts but won't fire

    I have a 2001 xv16 road star a few months ago my boyfriend couldn't start it because the starter relay and the bike was left outside and rained on. We drained the gas and tried to bypass the starter relay it would start but after several n of failed attempts it began to sound like it was flooded. Moving forward a week we changed the relay and instant power but still no fire sprayed starter fluid into the air filter tries to fire but instantly cuts off....oh forgot i put 87 gas in it because tank was empty.....super bad choice drained it again and also drained the petcock......added the 93 fuel sprayed the air filter still sounds flooded i don't hear the fuel pump turnjng on but wonder if that could really be the 8ssue i am starting it n with a jumper box battery is old but bike is carborated why do i need a fuel pump i really just need to start the bike to drive 3 miles show it starts than i can do proper repairs anyway i get it going without buying a fuel pump need to drive it tomorrow...

      When was the last time your Bike was running? In other words, how long has the Bike sat? My Bike sat for 3 months and I forgot to drain the carburetor and the carb varnished up on me, I had to tear the carb apart and clean the old varnish out. BTY:

        October it ran about a mile when we got back it wouldn't start again.....i diagnosed the relay but since it was coming up winter we didn't attempt to do anything to start it. I am going to check the plus and see if their wet my boyfriend thinks fuel pump i honestly being a mechanic (not a bike) it doesn't make sense why the bike even has a fuel pump it's not fuel injected

          Drain the fuel out of the carb, hit the key and listen for the pump, if it's tickin', it's working. Also the Bikes were designed before ethanol fuel, me thinks you carb is buggered up, they are easy to work on, not much to them. In the pic the float, Needle and Needle Valve seat removed. If it is varnished up, get a can of carb cleaner and remove all rubber from the Carburetor.

            Carb definitely buggered thank you for your help

          The bikes are designed to run on low octane gas so the 93 isn't going to help anything and is a waste of money. You don't need the fuel pump on a carbureted bike, if you will search this site you will find the info to delete the fuel pump. I t's not expensive or hard to do.

            Key - “Got rained on”. High probability there is water in the tank, petcock, fuel pump, fuel line and carb bowl. Drain all, fill with fresh 87 fuel and a heavy dose of Seafoam.

            I would put a new plug in one of the left side wires and crank it with the plug grounded. If you have spark try new plugs on the left side and try firing of with starting fluid. The bike should have fired on the starting fluid before even with bad fuel or bad fuel pump. Buy the way, nice bike. Looks like someone has spent some time and money on that one.

              Watch the accelerator pump nozzle at the mouth of the carb while turning the throttle. If no fuel is visible then the carb is empty and the fuel pump is likely the culprit. With the look of that tank the fuel pump might not be there, can't tell without seeing the left side of the bike.

                    Sure bypass all with a pc of 5/16" fuel line from the petcock straight to the carb inlet with hose clamps.It will get you home but might not be the best for high speed and starve a bit.

                • #12
                  Also this maybe a real stupid question but do i have to remove the carb in order to drain the fuel?

                    Drain the tank at the petcock on off valve. the carb has a drain bolt on the bottom of the carb bowl. So no.

                  Update I found the plug the drain plug for the carburetor and was able to drain the fuel from the carburetor we drain the P petcock yesterday but when I drain the carburetor it was milky and white and so now we can't turn it on because we have to start the battery the battery is dead but so far that appears to possibly be that the issue is once we have a fully charged battery being restarted I'll let you guys know thanks but will the Milky gas actually be the problem like where it doesn't fire like it fires and then cuts off is it doesn't it doesn't allow it to idler anything's so but it turns over and it just won't complete its fire if it fires it sits with the starter fluid then it just shuts off immediately

                      Fuel pump comes on for about 10 seconds and if the ECU detects no rpm it shuts off.

                    Run some fresh gas though it and some seafoam and hope for the best.

                      You or whoever is working on this bike should put the carb back together and take this bike to the dealer.

                        Never removed the carb or any part of this bike

                      Well lucky i don't think you read the entire forum because i have not removed anything including the carb from this bike. I have only replaced the starter relay and drained old fuel. I cleaned the air filter and jump started nothing has been removed and can't take a bike to a dealer until i get it started.....ugh and well draining the carb definitely was part of the problem because its almost firing up....cross fingers once battery is fully charged we will be on the road to the dealer where i am trying to take it today to sell her....

                        There you go! Keep it simple......Rain is the key factor and a common problem. I converted my bike to run on milk, but once the price of a gallon of milk surpassed gasoline, I converted it back!

                        It is likely still sucking water/milk from the tank, fuel pump, fuel lines, etc. carb is likely turned to cheese in the passageways. Give it a heavy dose of Seafoam in the fuel. Run it at any rpm it will stay running to get the Seafoam through the system.
