Cosy adventures continue - beginners learning curve.

Today the bike and I had a good long run!  But the Engine died on the A82 while overtaking! eeek Stuck between an off ramp and a hard place!!  I got Rescued by my recovery chum.   Initial diagnosis suggested I had knocked the kill switch during the manouvre but neither of us could be sure what position it was in! Idiot Check!

Continued and then discovered hesitation when throttle is full for a long time 55mph plus.  It died once more.  Returned home a different route  (sub 55 mainly)  with no problems.   I didn't exceed 55 for long enough to tell,  it seems to be extended full throttle it struggles with.  Closing it again solves it or if its really bad when it stops, just restarting seems to fix it.  But it takes a few attempts and it's like the carb is empty.

What do think?  new fuel pump and filter in order? 
Will be getting my pal to give me an escort for some 60mph fault finding I think!!!

I LOVE this Nodding and waving thing!    I feel like everyone knows me!  Cornering is all coming together too, smooth and relaxed.

Sounds like fuel starvation. Probably caused by a blocked fuel pump breather. It is a common problem on Leader engined bikes. You need to find a small disk of foil - looking like brass or similar that is on the underside of the fuel pump. Clean it with a clean rag using white spirit or similar.

If that doesn't work the fuel filter may be blocked, or a hose in the vacuum system that powers the pump may be splint, but try the suggested 2 minute fix first. The fuel pump is mounted on the right of the frame alongside the engine on most Leader engined bikes, just where the breather breaths in muck thrown up by the wheels.

Hmmmmm mine appears to be bottom left beside fuel tank and needs lower panel off?  (Judging by haynes manual picture of the item i'm looking for.)   I dont have anything on the right except ht coil and spark plug.

How many panels need to come off!!  Is there an order that makes it easier?

I have a big pile of screws yet everything is till firmly attached or inaccessable. 

I found daves list - surely not all these are neccessary for one belly pan?

Screen - 3 bolts
Supports - 2 bolts
Perspex deflector - 4 bolts
Seat - 3 bolts
Nose - 5 screws
Fairing - 10 screws
Speedo cluster - 4 screws
Digidash 3 screws
Handlebar shrouds - 3 screws
Tunnel top - 2 screws (plus seat removal)
Side panels/Bellypan - 8 bolts and 12 screws
Rear lower panels - 3 screws each
Rear painted panels - 3 screws each
Rear mudguard - 4 bolts
Rear grey trim - 2 screws
Front mudguard - 4 bolts
Fascia panel with glovebox - 1 bolt (plus removal of fairing and tunnel screws)
Headlights - 3 bolts
Rear lights - 1 bolt each
Footrests - 5 screws

Might be lower left - I have never had a 125 X9. As for the belly pan - it is about the last thing to come off the frame - I know - Jim halped me replace a broken one.

I would be surprised if all this had to come off for the fuel pump though. It is powered from the engine vaccum on a leader so is normally near the engine. I assumed it would be accessable from underneath after removing a lower panel three screws - one hidden behind the rear panel, or at most an upper panel, which requires a long hex key. Others may know more.

Its a non evo

I attempted a panel strip but everything still attached despite huge pile of screws.  its possible i was being too gentle.  Its raining so I have buttoned it all back up and abandoned for now.
Just to check I'm not being an idiot here are some pics.

It looks like the vac pipe comes out the top by the carb and descends alongside the fuel pipe down to the front left beside fuel tank.  I cant see a fuel filter anywhere but there is a non return valve up at the top.  annotated pics are here http://www.cosybike.co.uk/transitpics.html



The white protrusion has a foil breather?  But thats carb related is it not?


The pipe looks in good condition at the engine end.

Hurray!   Suspension fixed - The rear wheel steering is gone! eek!

But its Back to scooter hospital for alternator/regulator attention I think. There seems to be a lack of volts to the extent that the battery flats and it just dies.  Surely it must go after this! 

Also discovered the perils of greasy garage forecourts with slight slopes - Falling off while stationary, petrol everywhere, me skiting about trying to stand up, carnage!, but the mirrors are easily fixed.  I suppose thats why you start with a crappy bike! 

[cosybike]

Diagnosis - 1 Coil short of a full alternator...not unlike the owner then...sending away for rewinding.

Fingers crossed I start adding ride reports to this thread....

[cosybike]

Could it possibly be true....Never have I been so quite excited about 14 volts before.  Todays long distance charging and power use test seems to have been successful.  The alternator needed rewound.

And we saved a Hedgehog crossing the road in the town of Busby.  (presumably the hedghog is called Busby?)  Stopped the cars behind and commanded a bus to stop!  Scooped up and into the undergrowth in his direction of travel.

[Dave Milnes]

Was it expensive?

[joyce]

What, the hedgehog??

[Dave Milnes]

Yes re-winding a hedgehog around the stator coil doesn't come cheap.

[Gary]

Wouldn't cat-gut be cheaper?

[Dave Milnes]

Harder to run over though!

[Gary]

But easier to pick up.

[cosybike]

£160 Is that dear? average? labour is included in that too. 

Today's cosybike takings paid for it!   Fashion show lighting fee    No glamourous models

[jimc]

I've lost the plot - £160 for what exactly?  If for the total work in getting the stator re-wound with not a finger lifted by you - cheap I'd say.

[cosybike]

Breather cleaned by me - still cutting out at speed,  has to be filter or vacuum pipes or pump.  gonna be replacing the lot!!  If that fails I'm gonna shoot myself.   Charging is good and batteries are keeping their power though. 

Could an electric fuel pump be fitted instead?

[Dave Milnes]

One from a 250 Evo is cheapest, smallest and simplest. It will fit in the same place with a bit of jiggling. CM10901
