Title: Brains trust required
Post by: steve porter on Thursday, 09 July 2020, 08:50 PM
So the last couple of days I have noticed a hesitation when giving it a handful from low revs in a high gear that clears itself if I roll off and then roll on less enthusiastically, and today I gave it a serve away from the lights and it spluttered and then cleared itself. It starts, idles and runs perfectly when  just riding around normally.I'm thinking the dreaded tea bag or hpf blockage, but not sure if these are the symptoms or not. All advice greatly appreciated

No brains trust here, however, I'd be checking the fuel filters & the air filter.    Big handful n she coughs / hesitates, is gotta be either fuel or air.  I'd say low fuel - for whatever reason, could be filters, injectors getting blocked, although not likely.  Fuel line not kinked?

Aye I'd start with fuel filters too.

Yea, feels like fuel, so will do the HP bypass this weekend

I've just started running a magnetic tank bag and my first thought was that it was blocking the tank breather, but yesterday left the bag off and it still did it

just lifted the tank and water pissed out of the breather/ overflow hose, it was pinched between the tank and the fuel line, my fault for not routing it properly,hopefully that was the problem, am using it today so will know shortly

Bastard, still the same, so picked up the bits on my rounds inc air filter and plugs HP filter and hose, so filter cleaning and bypass time over the weekend

i`ll have a look, might try the propane method if the filters don`t seem blocked

Tea bag was totally covered in rust and shit , but the HP filter doesn't seem restricted  from what I can tell anyway, squirted a whole can of carb clean through it both ways anyway and no crap came out,so will see how it runs next week, pissing rain here all weekend

Hope so, but zero experience with this so won't know until I ride it

@steve porter
This is why I added an inline filter before the teabag .
Helps reduce and crap building up where you can't easily see it .
Hope all is well when you get to try it .
Once summer has relaxed abmnd the rain is less . :cheers:

I'd seen the pics and read the stories, but was still surprised by the amount of shit I found

Working perfectly again, inline LP filter ordered which  I will install ASAP

Glad to hear it. 

The other day when i had my tank off i found mines still got the tank cleaner rolling around inside (a couple of magnets in a plastic cage) does yours still have this? I had the fuel pump out to clean the teabag and hp filter flush.  There was some rust flakes but all stuck to the tank cleaner.  Works well i think.

Would  seem to me if you're  getting a lot of rubbish in the teabag, your tank cleaner could  be missing or de-magnetized?

Just a thought....

First I've heard of it, when I do the filter I will have a rummage around

All my years with 14, never heard of tank cleaner.
Title: Re: Brains trust required
Post by: Hooli on Tuesday, 14 July 2020, 09:38 PM
Sounds like an aftermarket thing to me.
Title: Re: Brains trust required
Post by: Eric GSX1400K3 on Tuesday, 14 July 2020, 10:37 PM
Next time i pull the tank off abd fuel pump out i will take a photo of what i call the tank cleaner that's rolling around inside.
Title: Re: Brains trust required

Gotta be aftermarket, I've 2 tanks & neither have that item.
Title: Re: Brains trust required
Post by: Hooli on Wednesday, 15 July 2020, 06:21 AM
I've been inside the tank of five 14s over the years & none have had it.
Title: Re: Brains trust required
Post by: steve porter on Wednesday, 15 July 2020, 06:28 AM
does sound like a good idea though
Title: Re: Brains trust required
Post by: Hooli on Wednesday, 15 July 2020, 06:38 AM
It does aye. I suspect a big magnet on the outside of the tank would do a similar thing too.

Magnets in a plastic bag rolling around? Could someone explain how a magnet could roll around in a steel tank please.
Title: Re: Brains trust required

Eric, put a pic up of this thing.
Title: Re: Brains trust required

Will do. Give me a couple of days.

 OK so curiosity got the better of me and so i took the tank off and fuel pump out last night.

Here are the two widgets that roll around in my tank.  Apologies, they are not magnetic, but looking at the inside of the tank when tipped on its side its perfectly clean and zero rubbish in the teabag, i think they are doing their job amicably.

The last photo is of the inside upper side of the tank, i could not get one from the side or lower edge.  Tank is original Dec 2002, still has the inspection sticker on the underside up near the head stem.

Thanks for the pic's Eric, I've never seen them before.

I had similar, but not the same, looking things in my old Ducati tanks that were Tin pellets in cages  that were supposed to help with valve cushioning post leaded petrol

Decided to go a mesh cleanable LP pre tea bag filter and fitted it in a position that I can keep an eye on it just by lifting the seat. within a couple of minutes  It had already stopped a small bit of crap from reaching the tea bag

@steve porter
Like it .
I did this year's ago and it does save some of the crap getting to the teabag.
And easy to see.
The problem with the teabag is it's not easy/quick to get at so often gets forgotten untill there a problem with the bikes running.
When it should be checked regularly as part of routine maintenance/servicing.

Now I have my head around it I have ordered the recommended filter and will do the HP bypass, I'm pretty sure it will sit in front of the LP one I just did, but will test fit for room first
