Question about 1990 Honda CB 1

Open Question

I have a 1990 Honda CB1 400F that was having problems idling. I would start it with the choke on all the way and the bike would struggle to keep running and then slowly build up to 2000 rpm. After the engine was good and hot everything ran okay. I noticed that the choke lever was really had to push, so I lubed the cable up and all was smooth. I figured since I had the access to the carbs that I would blast some carb cleaner in them, I have no idea how long it has been since they were cleaned. I put everything back together and ran the bike. It sputtered because on the carb cleaner and so I left it over night. I tried running it the next day and it ran sweet. Then suddenly it mysteriously died and it hasn't run since. Did the carb cleaner do something? Did I mess something up?

I have a supermagna and used fuel stablizer once and it wasnt fit it gummed my carbs up,ive cleaned mine often and it isnt rocket science,remove the tank airbox assembly,loosen up the boot flanges that hook the carbs to the motor(ones on carb)then remove the carbs,then the cables,choke and throttle,do not remove carbs from assembly(leave all 4 together)remove the bottoms and tops of a carb,removefloat and jet,then remove all the brass jets and clean them so you can see through holes,,blow out all the holes in carbs,and reasemble,works for me every time,about two hours to do,good luck

SOURCE: will only run with full choke and absolutely no throttle.

Carbs gummed up. Need a serious cleaning or a full ruubers replacement/rebuild kit. Gas turns to gummy when left stting in the fuel bowls.

Use a couple of cans of Sea Foam.. best stuff in the world.

SOURCE: Honda CG125 stalls when choke closed

Hi mate, what you want to do is take a dump in the petrol tank. This usually cleans the carb out with your **** and works surprisingly well.

Backfires at idle (sometimes) but seems through air intake not exhaust ? Bike struggles to start without choke when warm ??


A bike that backfires through the carb has ignition timing that is too far advanced. This will also cause bad starting. Get the timing fixed.

2007 Honda shadow spirit 1100. Has set up for 6 months and will fire but will not idle without choke on full.


Failure to idle (or even start/ run) without the choke is indicative of dirty carb(s), partially clogged slow jet. Leaving a bike to sit with un-stabilized fuel is inviting problems, ethanol is the culprit.

Bike start but when it is normal working temp it cut out and struggle to start and don't pick up refs


Sounds like a carburator or fuel injector problem,,,If carburator the automatic choke's heat sensor is sticking...if injectors, the elec tronic pick-up for engine temp is faulty.

My 2002 honda xr200r will only start with full choke on and at that I must play with throttle


Although there are three positions to the choke, full choke is applied in the Up position. If you are having problems starting the bike try adjusting the idle and air adjustment screws. Idle is on the side and air is centered under near the float bowl. Consult the owners manual for the # of turn out from an easy seat. If that doesn't work remove the carb and all jets and screws and clean. also make sure that the decompression cable is in good working order!

I just bought a 1999 Honda Aero and it did not come with an owner manual. Where is the choke on this bike. Is there any free down loads with "getting started" on the Honda Aero/shadow of this...


The choke is on your left hand handle bar, it is the black slide down lever. 1. Push the lever inward to choke the bike 2. give the throttle two turns and start the bike. ( do this so you don't drain your battery, even with a new battery you need give the bike the gas to start or you will have to recharge the battery) You will hear the engine change pitch when it warms up, push the choke upwards and the bike should idle on its own.

What position should the choke lever be when starting a cold 1986 Shadow motorcycle?


The rubber cover can be tightened or loosened to hold the choke lever in place. I like to set the rubber cover just tight enough to keep the choke out but if I start driving it starts to slip back in by itself. If you pull the plunger all the way out it will raise the idle and should be the best position for the initial start. You may find you have to touch/ twist the throttle just a teeny bit to get the first pop. Then run full choke for the first 10-20 seconds till the fast idle is steady. Then push in the choke till you have a slower more comfortable fast idle. At 45-60 seconds push the choke in just enough to keep it idling. It should be safe to slow drive with the choke out about a quarter of the way. Take the choke off completely when the bike will idle on it's own 1 to 2 blocks down the road. If the bike is still boggy on take off put enough choke back on to get a smooth take off , then while slowly cruising during warm up push the choke all the way back in. Take it easy till the engine is warm.

Stalling when starting


I would check that the rubber seals for the Choke circuit are in good shape and that the choke is actually working properly.
