1988 GL 1500 Starting Problems

Have changed fuel pump on my 1988 GL1500 but still acts as though it still is not getting fuel I did get it to run if choke was kept on half way but now acts as though it is not getting fire to the plugs?

    Yes on and off for about four years I would start it up and run it in the garage to bring the engine to op.temp. but did not drive it but very little and noticed as time went by that it started acting like it was starving for fuel and started noticing I would have to run it on choke part way just to get it to idle and accelerating was out of the question. Does the 1500 have a petcock i'm not aware that it does.

    I pulled the carbs and found that jet #20 on both carbs to be plugged I cleaned them and put them back in and found jet #19 to be clear. Can the obstruction in jet #20 cause the problems that I had mentioned or should I look into it further?

    I tried your suggestions and they worked now all I have to do is balance the carbs. Thanks for the help.

    was the bike sitting for a while before you rode it again? carbs might be dirty internally.

    is the petcock in the ON position or RESERVE position? if in the ON position, does it have enough gas in the tank? if you move it to reserve, does it do the same thing?

Petcock is #4 in this pic:

you should be able to switch between ON and RESERVE with this lever.

sure sounds like its starving for fuel as time went on so something is gumming up,

i would check to see if the fuel filter is clogged (#2 in the above pic) and if you can reach it, disconnect the output of the filter and see how it flows. if its a good stream, then focus on the carbs. if it doesn't, then replace it.

carbs may have gum & tarnish in them. you'll have to remove them and give it a thorough cleaning. if you're not comfortable doing any of this, then take it to a dealer or independant shop. if you're ok with removing the carbs, but not comfortable cleaning them internally, then take them to a shop that can do this.

if you can get them off and want to see just how bad they are, then remove the bowls (#5 in this pic):

and see how bad the gum looks. it will smell like varnish and look either very sticky or very hard. be careful removing the bowls to keep the gasket in one piece. it it tears, then you'll need a new one from honda.

pay particular attention to the jets (#19 & #20 in the pic) as these little holes plug up almost immediately once gas starts going bad. you can remove the main jet and slow jet and give them a cleaning with carb cleaner and a bread tie (with the plastic removed, using it like a pipe cleaner). they are brass so be sure not to deform them with tools.

going any further will take patiences and a little skill, but you can try the above at a minimum and put it back on to see if it will run.

good luck.

99 vulcon 800 only runs with choke pulled out... why

Your mixture may be too lean (too much air, not enough fuel). When you put the choke on it "chokes" the amount air in the mixture and enriches the fuel ratio. If you can find the air/fuel mixture screw on the carb (I have no idea if there is an adjustable one or where it is on your model, sorry) then screw it in gently until it seats softly counting how many turns to seat it. Write this number down, do not rely on memory and at least you then have the original setting to get it running even though you need choke. DO NOT OVER TIGHTEN and then back it out about about 1 and a half turns and then start the engine. If it runs without the choke you will be near the setting required. If it doesn't run then try another half turn out and retry. No, then turn it back to the one and a half and turn it half a turn inwards. Still nothing, then soft seat again and turn out two and a half and try again. Once you get it running fairly smoothly, then it is just a case of fine tuning it only this time with the engine running. Just screw it in and out as required, listening to the engine speed and once it is idling at its' fastest, that should be the optimum setting. Easy job really, just a matter of finding where the screw is. I cant stress highly enough though about the soft seating of the screw. Too tightly seated will damage the screws face so just turn gently until you feel resistance and don't force it.
Hope that is of some help.

96 gold wing 1500 changed the oil and filter started bike once now will not start

Check you kill switch. Changing oil should have nothing to do with starting. Changing fuel filter is recommended. Could be a fuel pump problem. Is fuel pump getting power. Check fuel pump relay and or fuse and find any connector in the wiring that feeds the pump and inspect. Could also be an ignition problem. To bettet answer, I would need more info.

I have a 1998 Honda GL1500 it is running so hot that it is discoloring the heat shields. The gauges shows normal. Any suggestions?

If you are running stock pipes, i would say your carbs are to blame. After periods of non use or high mileage the jets build up with debris and decrease the flow of fuel. causing the engine to run hot.

When my gl1500 gets warmed up, motor oil leaks out of a hose directly underneath the crank case. how do i stop this oil leak?

too much crankcase pressure can be caused by oil level to high, or worn piston oil rings, thus drawing pressure from the combustion chamber into the crankcase. If your oil level was to high, then that is most likely the cause of your problem.
