coughing, spluttering, and dying...

[andym]

but enough about my man flu,

I'm having some trouble with me bike, and figured someone here would possibly know a man that maybe knew someone at some point some time ago that maybe knew a thing or two about bikes.

I've been using my intruder 125 to and from work for a few weeks now and with the odd hick-up here and there (runnin' like a bag of sh*t at times), I put some super unleaded in as recommended by a biker friend and it seemed to run fine after that. Unfortunately over the last few days it just doesn't want to play fair.

It will run for a while and then cut out (maybe a couple of miles tops), every time I stop at lights it will cut out and usually takes about 5-10 seconds to restart.

I was going to take the carburetor off and give it a darn good clean, but haven't got a clue how to do it.

So does can someone point me in the direction of a repair manual for a suzuki intruder vl125 (I've looked online and can't find anything).

Or if someone could explain how to get at the carburetor (do I need to take the petrol tank off), any help would be greatly appreciated as I have today off and need to get it running for tomorrow.... fingers crossed.

Thanks in advance

hi,you should have a look for the haynes manual and then you can do all your own maintenance

i know what its like to not have a clue how everything works

Haynes dont do a manuaul for 125 intruder & yes I think you would have to take tank off to get to carb propperly try this link for pdf , it may take a few mins to show ? & may help with stripping carb ? ( if its the right type & year ) https://www.scoot.bg/arhiv_na_opisanie_motori/125cc%20(VL125%20A4121%202000).pdf

Thanks Rusty, will check that out....

Rob, I did look and couldn't find any

cheers

Could be carb icing, my CBR does it in the really cold weather, i just try running with the choke on for aslong as possible and keep the revs above 6k. Try keeping your bike in the house at night like me lol.

You or the bike stay in the house Carlos?

OK I've finally had the chance to have a proper look at the bike, I took the air filter off and the first thing I noticed was the strong pong of petrol.... not too unusual I thought... when I took the foam out of the air filter there is what appears to be some kind of oil, water and petrol mix.... or light brown sludge. Anyone.... HELP

[c_dug]

If the oil has been over filled at some point I think it can vent in to the air box, nothing major if it is that, just the bike preventing itself blowing any seals.

[andym]

so will cleaning the carb sort it? and do I need to take it off to do that? cause I can't get the bloody mesh off the inside of the air filter

[c_dug]

Assuming that the oil in the airbox has just been vented into there from the crank case then it has nothing to do with the carbs at all.

Not sure cleaning out the carbs will do much to help the issues you are having either to be honest Either way since you have got it that far apart I guess you may as well carry on

Can't be any more help with taking your bike apart as I have never worked on an intruder before.

not a lot of the bike took apart atm, got the air filter (and mesh off), and there isn't any oil in there... what I did find was about 3-4 tablespoons of water (since it's so cold in the garage I decided to soak it all up with kitchen roll and set light to it.... and WOOOMMMPPPHHHH.... the kitchen roll went out.

Now I know moisture can build up in them parts.... but isn't that a bit much? if so how would I cut down on moisture build up?

[andym]

I've found a part called the air valve.... I've taken it off and too me it looks like there should be a button on top that can be pressed.... but it is seized solid.

[cloric_tzr]

have you checked your spark plug? im guessing it a four stroke? my tzr has pipes coming off my coolant system going to the carb to warm it up. do most other bikes not have this? carb iceing? new to me

If your engine worked on regular 95RON fuel, no reason it would worn ANY better on 97 RON 'Super'.
all it has is a couple of extra RON points which mean it can stand a higher compression ratio and a tad more advance on the ignition without 'pinking'.
If it didn't pink on 95, wont pink on 97, and your wasting your money on the stuff.
Next up; fluids in air-box.
Slimy stuff sounds like oil.
Flamable stuff, petrol
Neither is a good sign.
Most modern bikes have vent-hoses on the gearbox and engine that are fed into the air-box, so any oily vapour from the motor is sucked and burned, rather than dumped as slim on the road.
Likewise the carburettor over-flows.

Lets presume that the petrol was from the vent-pipes, that means that the float bowl (or bowls, does it have one or two carbs?) is over filling.

Means incrorrect float height; worn float valve, or sticking float valve, or.... I cant be arsed..... you need to clean the carburettor(s) and inspect all the niggly bits!

That's a certain. Still many other maledies that could be giving you grief, but petrol in air-box -> over-filling float-bowl venting to air-box.

Incorrect float hight will make the motor run rough. Enritchment from having neat fuel in the air-box make will make it rougher.

You need to sort and eliminate that one first. There may be other problems, but thats your starting point.

Next up; spark-plugs, at the very least, with fuel in the air-box and pottentially an over-flowing float bowl, your motor will have been running bludy ritch, I'd expect your sparkers to be as black as the ace of spades.

THEY need to be pulled, and at the very least cleaned and gapped, if not replaced.

If you have any facility for adjusting spark timing, that should also be done to eliminate variables.

THEN, if its not running better, we can start looking at other stuff.

And the mayonaise in the air-box, could mean that teh engine's been over filled with oil at some point, or been layed over far enough for som eoil to flow into the over-flow.... OR worryingly, that the bores are worn and you have 'blow-by' past the piston rings, allowing combustion pressure into the crank-case making it 'blow' a little oil through the over-flow.

Check the oil level, top up, to mark, and KEEP AN EYE On it. This can give advanced warning of major motor maledies.

Report back when carb cleaned and inspected.

Yes, you probably will have to take the petrol tank off to get at teh carb(s). May be possible without, but usially a lot easier with the tank out the way.

You'll also need to disconnect the throttle cable, and the choke, and the fuel-line.

damn that was a long post...

liquid in the air filter/box was just water (and oil, still not sure where that came from), tested the liquid by soaking it all up on kitchen roll and setting light to it.... and rather than a nice big fireball... it went out.

checked the spark plugs a couple of times and they look to be perfectly healthy.

I'm guessing that it was running like a pile of poo because the water in the airbox was getting into the carb from time to time.

haven't cleaned out the carb yet, but dried all the water out, cleaned the filter etc, took it for a test ride and ran perfectly.

Took it to work today.... I mean a friend took it to work today on the motorway (since I wouldn't be allowed on the motorway with a provisional), and while doing about 70ish suddenly the power just buggered off and left me to coast to the hard shoulder... I mean him to the hard shoulder. Was a bit of a barstuard to start again, and only fired up with the choke on full. Got to work and parked it up.... went to ride home and everything seemed to be fine for a couple of miles, I didn't take the chance on the motorway this time, but then it started spluttering and cutting out and didn't want to stay running.... only to find I had turned the tap to reserve tank to see if it ran the same and forgot to turn it back.

Rest of the journey home and there wasn't even a cough.

Hopefully fingers crossed it's sorted for a few days.... will need to do a few checks every week though to make sure there are no build ups anywhere.... that and go back to regular unleaded since it doesn't make any difference from what I've noticed.

Anyway.... thanks for all the replies

[cloric_tzr]

i dont see why it would be coughing and spluttering on reserve?
unless the pipes blocked i run my tzr on reserve all the time even with a full tank.

im starting to think from reading all of ur thread/replies/posts
that you may have shit floating in your tank causin blockages every now an then resulting in the said symptoms. take ur tank off empty it via where u put fuel in, into a somthing you can put the fuel through a siv see ehat you collect.
