Question about 1998 Honda VT 750 C2 Shadow

1 Answer

1998 honda shadow will not start

The bike has been sitting for a few months. tried to start it. It would run for few seconds then stop. This was on full choke. After about 30 minutes of back and forth it finally would stay running, but only on full choke. Finally got it to throttle up with choke off after about an hour, but would only run if you were on the gas. If you tried to let it idle it would die. Also, front cylinder would not get hot and exhaust from this cylinder would not warm up untillI was finally able to throttle it up. then it got hot. Replaced the spark plugs, now all I can get it to do is to run a few seconds with choke on, and then it dies. What is wrong?

Hi and welcome to FixYa,

Initially, a few possibilities you may want to check/explore:

  • stale gasoline;
  • clogged fuel filter (inside the tank above the fuel shutoff valve;
  • clogged, bocked, varnished, gummed carbs, jets, air pin holes;
  • stuffed air filter/box;
  • vacuum leak (rubber coupling, manifold side);
  • air leak (airbox base assembly seated/fitted on the carbs.
Basically, a general cleanup of the fuel lines, tank and the carbs. Sitting for some time tends to leave varnish like coating on most parts.

Good luck and Thank you for using FixYa. Happy Holidays.

Honda 5.5 hp stops

Honda had a problem with the gas cap not venting properly, but commonly it will run for several minutes at a time before stopping. 30 seconds sounds like possible fuel delivery problem like a sticking float or dirty carb jet..especially if you have to run it with the choke on. A bad air filter...very dirty, or oil soaked might do this. Check your oil level. Sitting, oil is a little higher level than when running and these motors will not run if the oil level is too low.

Well after you clean it out and get it running make sure you dump some sta-bil into the gas tank next time it is going to sit idle for over 3 months. the gas turns into a shellac which glues up the carburetor.

My bike hasnt been ridden for a few months, and you need to give it full choke to start and keep it going, it wont idle when the choke is depressed, It is A Vstar 650 Classic

was fuel left in the carburetors when you parked it your metering jets might be slightly clogged with varnish i dont recomend opening them yourself take it to a professional and next time you park it for an extended period of time close the fuel valve and leave the bike running until the carbs run out of gas "the bike will stop running when this happens"

Good morning I have a 1995 Triumph Daytona 900. I use the bike to get to work and leave it sitting in the sun all day. When the weather is hot the bike starts fine but after going a few hundred meters it...

Possibly the fuel tank vent system is plugged and the sun causes pressure changes within the tank. Try to park in a shady spot for a day to see if this changes anything.

Yamaha TW 200 starts but won't run.

If the bike has sat for a long period of time without being run - the gas that is sitting in the carb(s) will shellac.. Then the carb(s) would need to be cleaned and "rebuilt"..

Wont fire turns over faster than normal

if you still havent started the bike yet from sitting.then i dont think the choke has anything to do with your problem.but ether way take the plugs out.I think your piston rings are frozen from sitting.did u winterrize it?with the plugs out pour a little auto trans fluid in each cylinder.very crank the bike over to coat the cylinders. becareful it could be messy now let the bike sit overnight.the next day crank bike over again.but this time for a few tries.then install fresh plugs.and try to start it.p.s there will be white smoke from the transmission fluid. that will go away in a couple of minutes.then all should be good.
