My Baby is a non-starter!

Battery is good, but Im getting more and more suspicious of the fuel-map chip.

I bought it off Ebay around August last year when I put the K&N filter in to match the race cans that were on when I bought the bike. Shes ran fine throughout, (tan plugs are testament to that), and I have no reason to suspect the chip other than the fact Im getting fuel and sparks but no ignition.
Im wondering now if the chip has failed/is failing and is sending too much fuel through and basically soaking the plugs so they cant fire?
My thinking stems from when I was trying the plugs out against the head to check they were sparking. The rag I had covered the open plug-hole with must have accumulated and then released a lot of petrol vapour because as I was thumbing the starter and watching the spark the air in front of me ignited and I very nearly shat myself!

I now know the plugs spark and the fuel burns outside of the engine, (because of the extra air?), so it seems to me that there aint enough air/too much fuel inside the engine!
That make sense?
Unfortunately, I bolloxed the OE chip when I switched it out fer this-un so I cant put it back in to check!

Anyone have one I could try, (GregD or Bigun maybe as you guys are local)?
In the meantime, Ive ordered another race chip off Ebay, (will I never learn!?!?), but its coming from Spain I think so prolly wont be with me til the end of next week or the week after.
I need her back on the road NOW!!!

I haven't got a spare chip I'm afraid m8. Still on the original. Give me a shout if you want a hand with owt tho. A fresh pair of eyes might help.

Dont spose anyone would be willing to 'lend' me their entire ECU box, rather than just the chip, (they are buggers to remove/refit anyway!)?
That way, it would be a simple case of seat off, lift the ECU cover, unplug the two electrical connectors and then swap the boxes over.
No need to even open em up!

At least that way I can determine whether my box and/or chip is goosed.

I have an original chip that works if you need to borrow it

pm me with addy etc if needed

(And chips are not hard to swap!)

before you start getting deep in to it have you made sure the choke is working correctly.

Yeah; Checked all cables were moving freely when I had the airbox off n they all seem ok.
Theres deffo fuel getting through, so my theory is now that its too much fuel which is basically soaking the plugs n not allowing em to fire the moment the starter button is pressed.
Ive tried every conceivable way of firing her up; No throttle, full choke, half choke, no choke everything-inbetween-choke, fully open throttle and every combination I can think of, (after the fuel has been allowed to air-out and the plugs have been dried and/or replaced).
Its really stumped me this problem as there was no warning whatsoever and it seems to have developed while the bike was stood for a couple of days.
In summary; Im getting nice healthy sparks, (at least when earthed against the outside of the head), there is fuel coming through, (the filter n strainer are clear of debris, the fuel pump looks ok and it can be heard priming when the ignition key is turned, also the plugs are wet when Ive pulled em out and the smell from the end-cans tells me its blowing the fuel through n out), and finally there are no diagnostic codes showing apart from '0' when the ignition is on.
The battery is fine and the starter and engine are both spinning freely with pressure blowing outta the end-cans and there are no untoward noises that might indicate the sprag clutch or other mechanical failure.
So, to my mind either the fuel map has gone tits-up and its simply pouring the stuff through the injectors, drowning the spark, or the ECU itself is playing-up and not reporting error codes properley!?!?

Im really loathe to send her to M&S to see if they can remedy the situation, so my last idea is to try an ECU or chip that is deffo working and see if thats the problem.
Other than that, Im all outta ideas!

Oh, @ALI; PM sent fella!

You can have a shot with mine if you don't blow it up! Trouble is, I'm not available this week as i'm away for a few days. Shout up if you can wait!

Cheers Bigun. I should hopefully get Aladinsanes OE chip in the next few days to try that out, but I may still have doubts about the actual ECU itself if there is no change with another chip in.
Will have to wait n see!
Cheers all fer the help; Bunch o stars!

I can take the ecu complete with standard chip off mine and I'm working in Cramlington from tuesday, possibly rest of week if thats any help

Also if theres definately a spark, have you tried squirting easystart in?

EU-BLOODY-REKA!!!!!

Got the new race-chip today, (a 'Triton' from a seller in Spain; Not sure about quality or longevity...), that I'd figured I wouldn't see til next week, slotted it into the ECU, and voila!

That beautiful V-Twin music that I love and have missed so much was ringing loud in my shed!

I cant believe that after having the bike in bits all week, nearly setting fire to my face, and cursing all of Italy while I worked on her, that it was all down to the bloody fuel map on the chip failing!

Im just pleased shes fettled, though Im gonna have to wait to ride her as the engine oil has been a little diluted by fuel that was pushed past the rings when she was flooded a couple o three times.
Ive dumped the shitty-oil, but I cant find anywhere local that supplies 15/50 Semi so will prolly have to wait until the weekend to go hunting fer some.

Still, Ive had her running, (fer only a few seconds), and thats all that matters!
Iam one happy-again lil bunny!!!

Once again, thanks fer all the help and advice fellas; I love this site, me!

Dont laugh ok, but try ebay for oil. I bought off these guys, http://cgi.ebay.co.uk/Motul-6100-15w-50 ... dZViewItem

Very quick delivery and massive savings.

falcomunky · #27 Post by **falcomunky** » Mon Feb 18, 2008 8:42 pm

Cheers fer the link Syltiz. You or anyone else tried the Motul 6100 15w-50 semi-synthetic engine oil? Just thinking it does seem mighty cheap fer 10 litres!

Also, I was thinking of sticking some 10w40 in the bike, (I happen to have a few litres spare), and running her for a while, (not riding), just to flush out any fuel, then sticking the 15w50 in. Should be ok shouldnt it?

Syltiz · #28 Post by **Syltiz** » Mon Feb 18, 2008 9:48 pm

I have used that same oil for over 1000 miles and had no problems. I think its good oil, its just cheap cos it comes from Germany (I think anyway). All their oil seems cheap - check out their ebay shop.

falcomunky · #29 Post by **falcomunky** » Mon Feb 18, 2008 10:38 pm

Sold! Just ordered a couple, so should see me right fer the next oil change or two.

Cheers peeps!
