Guest Posted February 7, 2008 Share Posted February 7, 2008 New to the forums basically its my motorbike, (obviously) about a week ago I managed to get it started using some easy start and ran it for a while then turned it off, I come to start it again and it just wont start, I have replaced the plugs and fully charged the battery, (the spark is good) it is fueling and on full choke when starting (tried on and off and full throttle) and the leeds are in the correct order, but it just isnt firing, it did mis fire at one stage after I put the air filters on but that was the only sign of life , 1984 suzuki gsx 400 btw. We think it might be a lack of compression but I am not positive on that.Any help is appreciated! Thanks! Quote Link to comment Share on other sites More sharing options...
Stu Posted February 7, 2008 Share Posted February 7, 2008 drain the carbs clean them out and put new fuel in the tank the fuel will have gone off if its been stood and gummed up the carbs welcome to the site by the way Stu Quote Link to comment Share on other sites More sharing options...

Guest Posted February 7, 2008 Share Posted February 7, 2008 drain the carbs clean them out and put new fuel in the tank the fuel will have gone off if its been stood and gummed up the carbs welcome to the site by the way Stu how long does it normally take to go bad?, its been sat for less than two months? would it really go bad in that time?

Guest Posted February 7, 2008 Share Posted February 7, 2008 It may have gone a bit stale.If it was running well before then copression isnt your fault.Undo the screws at the base of you carbs and let the fuel drain.Give it some new as Stu says and try that.For a 10 minute job it has to be worth doing?PS Hi!!

Guest Posted February 7, 2008 Share Posted February 7, 2008 hiya , yea this seems like the way to go, I will drain the carbs out and all the fuel from the tank, (and pop it in my car!) I think there may even be a chance of a blockage in the tank itself, which I can test by taking the fuel pipe off but if I leave it on full it shouldnt drain out because of the vacuum? and when i turn it on to res it will let fuel out straight into the carb? is that right? if fuel comes out fine then it must be a problem with the carbs I guess, it must have a fuel filter I would have thought not that I know where it is, p.s thanks for the replies youll have to bare with me im still a learner when it comes to mechanics! espcially bikes Quote Link to comment Share on other sites More sharing options...
Stu Posted February 8, 2008 Share Posted February 8, 2008 if you pull the pipes off the tank no fuel will come out!!!the tap is on a vacuum there is a thinner vacuum pipe on the tap which opens the tap when you start the bike i would also check this too make sure there is no splits in it or anything start with the basics clean carbs new fuel if still not starting start looking at other things Stu Quote Link to comment Share on other sites More sharing options...
Guest Posted February 8, 2008 Share Posted February 8, 2008 well after attempting to bump start it a good 10 times and getting a lot of mis fires we dissconnected the main connecters from the starter /timer and all the other connectors and cleaned them all up dried it off and managed to get it running again seems all good at the moment touch wood! when is a good time to sell a motorcycle btw?

Guest Posted February 8, 2008 Share Posted February 8, 2008 just sounds like you got all the poo fuel out of the carbs then gave up Pretty much we cleared the carbs out and put it on res so it would allow fuel to flow through and flush the carbs, so it was fueling and sparking so we just thought we would go for a bump start, which I think warmed it up maybe which finally allowed us to start it , I will probably sell around may then?

Guest Posted February 8, 2008 Share Posted February 8, 2008 March April May doesnt really matter.No direspect intended but is it the GSX400 you are selling as the demand may not be too high.What are you expecting for it if you dont mind me asking?

Stu Posted February 8, 2008 Share Posted February 8, 2008 nah the fuel tap works on a vacuum so you need the engine turning to allow the fuel to flow into the carbs.......bumping it will cause a little vacuum and get some fuel in but only a little at a time Quote Link to comment Share on other sites More sharing options...

Oh dont worry im not expecting much for it, the only reason it may be in demand is it comes in just short of the 33bhp so is great for someone with their A2 licence, has mot and tax till september, was hoping for around 300 really reckon it wouldnt make it?

Guest Posted February 8, 2008 Share Posted February 8, 2008 I dont think so.A member was selling his ZZR 250 which comes into the same bracket and it made £321 on ebay recently.Nice looking bike too.I am of the belief that most riders today dont look twice at retro's unless you are old like me!!PM me a picture or two.
