Daytona 600

ok i know its not an sv! there is such a wide knowledge base on here i thought i would give someone on here a try.
a mate has a 54 plate daytona 600. it has decided not to start 60% of the time all of the time. i have tried disconnecting the ecu and reconnecting it, i have made sure the battery is fully charged, checked all connections i can see. cleaned clutch switch, sidestand switch, nuetral light comes on. kill switch operates normally, fuel pump primes and relay gives a meaty click. when it starts it is absolutely sweet as a nut. revs up to redline on the road so not a fuelling issue methinks. oh and i have ripped out the datatool factory standarrd s3 alarm and binned it! blanking plug installed in its place.
i am talking to various chaps on triumphtorque, and i try everything they say.....its not even my bike and i am now pulling my hair out. the guy does not have much spare cash to take it to a dealer so as a few guys on here have trumpys i thought someone may shed light.
oh and i have also told him to sell it and buy a curvy.

forgot to mention the bike turns over quite happily when not starting, voltage on battery is 13.5 at start,drops to 11.55 while cranking and goes back up to 12 ish when ign on and not cranked. when it does run battery shows 12.5 and a blip of throttle will see it climb into the high 13's so guessing reg/wreck not duff

It sounds as like something as simple as a loose connection might be the trouble, as the problem is intermittent. However the other probable cause is a sensor/electronics problem.
There is no realistic way to tell what and where the fault might be without some sort of diagnostic tool, Tuneboy for instance.
However such things are expensive, the only sensible way to procede is to take the machine to a suitably equipped dealer, probably a Triumph dealer, even though everyone, without exception, that works in the motorcycle trade is a thief and worthy of being labelled a 'stealer'.

TBH that voltage with it running is a little low imo. Tickover on my bike is 14.2V and at 4000rpm 14.4V. The battery should be 12.8V when fully charged. You say that when the bike is off the battery is at 13.5V?

Does seem a slightly odd issue ill agree... Ill try and think about it.

I had similar problem with a GSXR. It would start fine from jump but not from battery even though battery was otherwise healthy... changed plugs and all was well.

Ok so these honest businessmen will not be cheap

Do you need the expensive tuneboy keycode to do the diagnostic stuff?
See if you can find local boy who has tuneboy cable.

to be fair i have managed to track down a trumpet owner with a tuneboy, unfortunately he lives in chesterfield and my mate is worried about making it. apologies for the stealer ref sid. but have you seen how much a triumph dealer charges just to answer the phone! that being said, did manage to get a blanking plug for the datatool for free even posted to us as my mates wife would not let him spend any more on his bike! could the plugs really be a prob chris? as i said it runs lovely when it starts, but it is as non comittal as a politician as to whether it will.

I would have thourght its the plugs or more likely the coils. Does it have a problem after hes washes it? Mine just cranks over if i havnt put it in neutral stange thing that it is... Also it takes a while if i have given it a good soaking. So dont

nope he never washes it. he was using it through winter, as i said when it starts, it gets nice and warm , then i have redlined it up the road through the gears and there is absolutely no hesitancy or indication that there is a fault of any description. just wont bleeding start. then you shout at it, and vroom it will fire up. do that a couple of times then back to original problem! do they have a throttle position sensor on them? and would that make a difference, if so where would it be. i only know a bit about carbed bikes not a jot about injection. as sid has said it is likely to be a connection somewhere, but you take the tank of a trumpy and its like spaghetti under there!

I can't remember what you can and what you can't do without the key. You may well be right.

As above, may be worth asking the Tuneboy owner what can and can't be done without the key, before embarking on a journey the bike may not complete.

I appreciate that professional services do not come cheap - at the moment however the bike is the best part of useless, thus it seems to me a false economy not to spend whatever's required to at least diagnose the trouble. A Daytona 600 is a lot of money to have as an ornament.

Does it have an engine warning light?
