Stop, first do not do anything yet.sjparker wrote:Ok so took the bike into an independant mechanic for diagnostics this is what he's come back with:
"One coil pack has packed up the other one has a very weak spark also the sparking unit has burnt out. sparking unit is £272+ the VAT, coils are £124+ VAT each"
Should I go with the genuine parts or is there anywhere else to pick them up slightly cheaper?
Thanks in advance all!
I think its a very bad idea to take it to these dealers. You need to take it to an old bike specialist if you want the best service, or learn to do thing yourself. That diagnositc sounds like it could be sort of correct (not common at all but lets go into that)
Coils are indeed 125+ vat but they rarely fail, you can test them yourself following the service book on the website. A far more common fault is bad connection to the coils / faulty leads.
Many times people have replaced coils to fix the problem when the real problem was a poor connection and plug leads which were fixed as a byproduct of changing the coil, cleaning up the connections would have allowed the old coil to work fine.
If your coil(s) have actually failed id put a cheap second hand one in there, they rarely go wrong. I'd want to re-test the coils myself according to the book to be sure they have gone.
Sparking unit is parts book took for ignition box. If this has burnt out then how are you getting any sparks? It could be kind of faulty but unless they have already swapped it for a known good one to confirm then how are they provding the igntiion box is faulty?
Which leads me onto the next point. The ignition box does not just burn out.. overvoltage will kill it which is a classic sign of faulty charging system.
If the ignition box is burned out id want a full test of the charging system done ortherwise you could just replace all these parts to burn them out again.
It really depends on how the garage has proved all the parts are faulty, if done methodically it looks like a charging overload has burned the stuff out (common on this bike) so that is something you also need checking / fixing if faulty.. but then again this kind of thing can be caused by poor connection / low battery so could also be stabbing in the dark.
Not wanting to slag anyone off without knowing their process but you can easily confirm all of their diagnosis by yourself with the shop maunal and a multimeter..
The sparkunit aka cdi is long discontinued now so i dont know how they are giving you a price on that as you cannot buy them new anymore.... that is a bit suspicious
If the ignition box is fried your best bet is probably to fit an ignitech unit (its programmable which if a bonus if you want to fiddle with the bike but it also works as a standard box should you not wnat to fiddle, and its available to buy and its cheaper than the non existant stock)
I would even replace the coils until id tested them and proved they are no good.
