I just put in a tankful of gas after riding around with no problems. Immediately after putting in the gas the bike started sputtering, and backfiring and trying to stall out. I'm assuming it's bad gas since it was running fine just minutes before, but I don't know how to drain the bad gas. I also noticed that there was a loose hose on the right side of the bike, just under the tank. There was a little nub under the tank so I put the hose on it thinking that may be the problem, but with the hose on or off that nub I still have the same problem.

Re: Bike sputtering and stalling out when revving
If it is bad gas then you need not only drain the tank but the carbs as well.
If the tank has the valve with three positions on it such as on, off and pri.
then you need to put it in the pri position after you remove the main outlet fuel line from the tank and make sure you have a suitable container to catch it in.
On the bottom of the carbs you'll find a screw which i think requires a phillips screw driver. You'll need to back those screws out until you have a fuel flow coming from the bottom of the carbs. After that close down the screws and replace the fuel lines. Leave it in the pri position until after you have put new gas in the tank. Once, this is done then turn the lever to the on position and it should start. If it doesn't then it could be dirt in the carb or no fuel flow to the carbs re blockage in the tank filter. I do believe also, that this pitcock may have a diaphragm in
it. If it doesn't then you shouldn't have a pri on the petcock lever on the tank.
Try this before, looking anywhere else.

Hi Bruce, might have gotten some bad gas. Drain the tank, clean the fuel filter, check the bottom of tank for rust, dirt, water ect. Then ckeck fuel pump pressure, refill tank with a gallon of fresh gas from a different source and take it for a ride. good luck
Chances are there is a water build up in the carb float bowls. The water comes from condensation in the gas tank. Try draining the carbs. Another possibility is carburetor main jets partially plugged up. You must clean the carbs if plugged jets are found to be the problem. Please rate my answer. Thanks.
turn left, sputter, sputter, pop! sputter, sputter..............vvveeerrrooommm !? WTF? Crazy 91 Honda CRX just became a death car tryin to get through an intersection. Checked all my wires and ended up in the gas tank tryin to put the fuel pump back together. POS pump is in the left side of the tank!? So if you got a few miles on it the fuel pump screen can fall off. Turn left and the last 1/8th of a tank goes to the right leaving a 3/4 ton chevy in your girlfrends lap...well almost. I still got the CRX, the girl got droped off at the car wash cuz she smelled like poo.
The sputtering was a bit of water in the bad gas you got and the smoke was probably from a bit of diesel fuel that was put into a gasoline storage tank in error. The temp guage going bad is just one of those things that happen from time to time, probably just a bad sensor. The idle speed change is a bit quirky but easy to adjust. Stick a fresh set of plugs in the bike and the starting problem should clear up.
You drained the tank but did not drain the carbs. Plugs should not need to be changed. Contact your states weights and measures department. There is groundwater and trash getting into the fuel storage tanks. Gas may be leaching into th soil.

It sounds like you probably need to replace the fuel filter, or you may have alot of trash in the bottom of your gas tank, possibly even water in the gas. If you can, take the tank off and clean it out well, making note if there is any trash in it, by emptying it into a bucket so you can examine it. Go ahead and replace the filter if you find any trash or water in the gas tank. If it is ok, then the next thing would be to check the fuel line for aging. Sometimes in rare cases, the hose gets old and weak and when you try to pull fuel through it, it can collapse and essential stop the gas flow, just as if you have turned the gas off, then when the suction is stopped the hose will open back up and appear to be in good shape. You can use your fingers and squeeze the line the entire length and see if it seems to feel excessively soft, if so that could also be causing your problem.
A few things to check/do
* make sure there is no animals living in the airbox
make sure your idle is at or around 1200rpm +- 100rpm
start looking for someone in your area that can do a good fuel injection set-up
what do the spark plugs look like? is sounds rich
the clicking and hissing is the fuel injectors and the air bypass , when the air bypass screws are out a bunch it can get loud. screwing these in will richen the bike and lower the idle. I would bet that they have been used to get the idle up and that is why they are loud.
The techtron will work fine as you have it. I doubt that it will help what you have described.
I would do the easy things yourself (new plugs and check air filter) and find someone to set up the fuel injection properly. plan on around 1-2 hours of shop time to set it up. They should also be able to read any codes if there is something wrong.
sounds like the throttle cables need to be looked over .( he get everything back to where it was before the lubing?)as one may be out of sync with the other. the oil change has NOTHING to do with the sputtering and surging ,stall .it would only apply if the clutch was slipping and that would make the bike rev with the car oil.
