Hi all,bike is up and running.All it needed carbs,fuel pump and all fuel system cleaned thoroughly.Thanks to all of you guys for help.
Now trying to sort bloody brakes with pistons dead stuck in calipers,what a joke,any ideas on how to get them out?thanks
-
Hi all may aswell put my penny in, lol. l know you said you got a new battery but have you checked to see how many volts it got, new or old it still could be bad battery. Will need the full 12volts after charging to help start it, if below ( like 10 volts) you may need more powerful battery. You said it has fired but not started is that fuel cock tap working on main and reserve tank? is fuel getting to the carbs? is the chock working aswell? . have you checked all the spark plugs for a good spark in each. If you got a good spark in each its could be fuel, if not wiring. try a volt meter and test bulb. you could also get a spark plug tester.
Hi Nick,thanks for reply.When i try starting the bike battery is always fully charged around 12.8 v. After all kind of checks i've done and with help of you all i thinks its either fuel not getting to carbs or most obvious carbs need proper cleaning.Kind of cleaned them other day but couldn't get to the rear of each carb as screws are dead stuck.So will give it a last go this week.Thanks

Sorry had computer issues, so its a vacume pump?
Whatever if you cannot prove thepump yet then yes the carbs as already said are going to need a clean. Take your time and don't interchange parts between carbs do one at a time and have the digital camera handy and take lots of pics so you don't get lost putting it back together.
Tried again with fully charged battery,didn't want to fire .So tried starting it with Easy Start ,it started kind of running whilst i had Start button on with little throttle,once i released it stopped and didn't run again.Probably dirty carbs at the back need somehow take them apart completely.Any more suggestions?Thanks

Oh,no thats ok.Sorry had computer issues, so its a vacume pump?

Yes its a vacume pump and unserviceable part unfortunately.Tried cleaning the carbs,cleaned i would say just just front of carbs as couldn't unscrew back of the carbs without completely damaging the screws.So put the bike together again.At first couple attempts it was just started sound then engine was trying to sstart with sounds kind of puf puf puf at which battery started to die,so battery is fully charged today,will try again later .Thanks

Anyone

Ok,if anyone reading this thread,squirted some carb cleaner in to carbs still attached.(done it lazy way).tried starting the bike,bike started and was running for about 5 seconds->stalled.tried to start it again and there was a big bang some tiny smoke was out of hole in exhaust system hole and smelt carb cleaner.touched the hole with finger and there was some carb cleaner.
So i suppose during all 5 secs engine was running on carb cleaner???
So i need to do proper carb overhaul?
Thanks
-
Yes but it won't be causing this as the bike hasn't run yet. It only causes issue when the fuel is drawn from the tank faster than air can replace it.
Your next step is to prove the fuel pump or bypass it and use some sort of bottle with fuel in it to gravity feed the carbs. Till then we cannot move on.
Also if it makes any sense,there is some kind of tiny howling/whistling sound coming out of fuel tank cap now and then

Hi again.Took the fuel pump out,took it apart haven't noticed anything special although i'm not the expert.pump is run by vaccum not electric one.took the fuel hose which goes from pump to the fuel hose joint which is in the middle of 4 carbs.And noticed the plastic kind of plug,plugged in to the fuel hose joint,couldn't see how fuel would go through that plug so took it out.got bike together,started still same problem,not firing,just starter sound.so is it time for carbs to be cleaned?don't think its difficult job but will have to do it on my drive:)
-
Haven't doneanything on a bike today,but read that fuel tank breather hose IF its plugged can cause bike stalling,is it true?thanks
-
Ok check the pump next then, best to work through logically or you get lost and miss things. Its normally something small that causes the problems.
Did the bike run ok before storage?
Got no idea as it was standing for 2 years before i bought it.i removed the spark plugs and squirted some petrol and it fired,so something with fuel distribution
-
Yes but does it inhibit the bike starting when the wires are connected together, or not connected together.
Bike turns over same with wires as they were or connected together,bike just don't want to fire.seems like fuel not getting anywhere.thanks
-
You might want to confirm what it does, depending on the wiring you may have made it definitely not start.
Checked on xj600 service manual and some over websites ,says it clutch lever safety switch,same i've done with side stand switch as it can be problem.So now on carbs or fuel pump otherwise its mystery.I'm in to the cars,but bikes are more complicated for me as its my first bike.cheers
-
Hi again all.Drained the carbs today,still can't start it.tomorrow hopefully going to remove carbs completely and try to clean them.Anything esle i should look at ?It feels like no fuel is getting to the engine itself,may the pump be faulty or something like that?thanks
-
Never done a XJ, as far as normall practice goes its an old bike which is a plus. The carbs won't be all fancy they will just be regular cv carbs so they should come off together mounted on a rail of some kind. May have to pull the airbox to get room?
Be worth having a look around the float bowls though as the older stuff quite often had a drain point on the float bowls so you could drain the carbs down, my TDR has and that is a 88 bike.
Yeah buddy was thinking about draining them first aswell.Found an unpluged plug near clutch lever,so bypassed them by connecting 2 wires together.still same problem.Side stand a bit greasy too so will try to clean it aswell.
Cheers

Unlikely on a 20year old bike, worth making it habit to hold the front brake and the clutch as you press the button though.
2 reasons,
1 Pulling the clutch reduces the load on the starter as the clutch will not transmit as much load, some but it will give the starter and battery an easier time.
2 If it starts and you do have an issue holding the brake will help stall it, the back brake may work as well but in my exp if something happens you grip tighter,and both feet on the floor is always better.
If you didn't drain the carbs even though you added new fuel you still have the 2 year old rubbish in the carbs and much as you might hope you won't draw the new stuff through. It will gradually dilute as it blends. You would be cranking it for hours before it will go if thats the cause of the prob.
Yeah you're right was thinking to clean carbs aswell.is it a big job?do i need to dismantle them completely?thanks
-
You did drain the old stuff out of the tank and carbs first?
No i didn't pal,do you need to press clutch lever when you're starting the bike?(it's my first bike)
-
Has about 2 gallons, from bone dry?
Will she go if you use reserve or prime?
How old is the fuel in the tank, modern stuff is crap and an engine that hasn't run for a while may need some fresh stuff to run. Where when its in regularish use it will be ok on older fuel. Like its used once a month
and the fuel is 6 months old before its filled.Hi Cynic,fuel in a tank is about 2 years old,so i've put 2 gallons of fresh one.still no luck.tried it in RES/PRIME/ON
It's my first bike,so thats how i start it:key is on,light neutral went on,pressing button RUN and then START.Oil light comes on,bike's turning over but not starting.
Cheers

Can you bump start it?
Battery is new and always fully charged before i try to start the bike,so dunno if it will help?
-
What happens when you try to start it? You said you have new plugs... have you checked for spark? You know you have fuel? Does the bike have a petcock? Is it in the on position? Does the bike require you to pull in the clutch when you start it? Is there a side stand cutoff switch? I know those are all pretty basic, but those are the only suggestions I can think of off the top of my head. If the bike turns over but doesn't catch it could very well be something entirely different. I'm sure the folks on here have loads of experience getting machines started after years of standing.
Hi Sacha,when i try to start ,it just turns over and over and nothing happening.took spark plugs out ,squirted some petrol inside and it fired.It has about 2 gallons in tank.Petcock in ON position.
Removed tank today and cleaned couple hoses as thought there is blockage,still no luck.
Thanks for reply by the way.

Anyone?

Hi again guys.Having a problem starting the bike.New battery,new plugs but it doesn't fire up.I know its obvious thing after all bike was standing for 2 years,but where should i start?fuel pipes,carbs?Thanks
-
Yeah,thanks pal will have to sort bike battery charger,saves me spending more if i wreck that new battery.thanksHi
Car battery chargers have a high charge output and Car batteries can cope with higher charge rates, If you charge a bike battery with one it can cause the battery to get very warm and this can damage the bike battery, but that is not to say you could not get away with it but I wouldnt try it, I have just brought a trickle charger from wemoto for bike 6/12 volt batteries it came with in 2 days and it only cost £15.52 delivered to my door.
-
Hi, NO you CAN'T, that's the simple answer cos a car charger has a different amperage to a bike charger, if you look at your car charger you will see the OUTPUT is about 1.3 to 4.5 amps but a bike one will be about 500 to 650 milliamps so if you use your car one it will cook the bike battery into a pile of crud, even if your CAREFUL it will wreck the battery cos it will be to much input for the battery to cope with. If your new battery has the seperate container of acid/distiled water pack with it then fill it as directed and connect it to your bike (it has been pre charged but the manufacturer) then start your bike and take it for a run of about 40/50 miles that should be enough for the battery to get fully up to power, that's all you need to do anything else is a waste of time. Hope that helps?
Yeah think you're right.problem is won't be able to take it for a ride as it has no mot or tax(bought it last week without battery).so just want to see if bike starts and engine running smooth and to see if anything else needed sorting out.Will it hurt a battery if i feel it with acid(and yes it came in separate container) and try to start the bike until i sort th bike charger?thanks
-
Hi guys,just bought a new bike battery with separate acid pack.Can i charge it with car battery charger?Although did a small research regarding that,want your all opinion aswell as answers to this question are ranging from " Oh yes,if used carefully" to "Oh no you'll explode the battery".Charger itself is Halfords make for engine 1800cc and over.Fast charge rating is 7.5adc,slow/standart 5.5adc
Any help is appreciated
and the fuel is 6 months old before its filled.
