Hi, Thanks for your response.Don't know really it just goes dzzzzzzzzzzt and then stops when ever the ignition is turned on. Big thankyou to oldgitonabike "you've been fantastic mate" got a spark using your method,(jump lead) + different plug ,now running sweet, selecting gears,etc,etc. Can't thankyou enough,I'd have never have found the stand problem. All the best,John. Would love to know for sure what the sound is when ignition turned on,power valve opening ??????

Will do tomorrow,time to get cleaned up now. Just wondered if this could have been anything to do with it and would it have damaged CDI. Will be in touch ,but please let me know any of your thoughts as I really appreciate your help.

OH NO ! please don't be mad at me (I did say I'm not mechanically minded) The plug when I last had it running was a 3 prong .Which I put in just before trying as newish plug.(Got a few plugs).Also doesnt look like it was fuel that stopped it as still some in pipe,worse news than that on examination of plug the one prong is against the electrode. Does this mean the consequences could be due to this and also costly (would this have damaged the CDI ?) Sorry ! I feel such a prat.

Hi "Sunny Shropshire" believe me when it comes to luck,I'm in short supply, it stopped when the fuel ran out .Sorry I don't know the year.Believe me I'm really baffled too.

Sorry only just getting back,sky has just opened up as usual & had to clear away (pouring down.)"The beauty of only having room to work outside" Will try this tomorrow.So do you think the CDI may be damaged with me having good results before when just holding firmly?

I've made sure powers on (sound of power valve ???).Then with plug in cap hold the plug thread against an uncorroded shiny head bolt and kickstart operated swiftly.(This is the method I've used in past when first tested this engine and generated good spark)

Sorry missed the last part. I have a very large syringe connected to upright metal above engine as only running for short bursts. Yes no kill switch,so as you say it will be 2 wires shorted together. After looking everything looks to be as was and connected. Its such a pain.

Is there a possibility the cdi has failed ?

Hi , No I've mounted on a very large block of wood (not very sightly but does the job) Just had the Mrs holding the engine at slight revs as I shifted up the box (didn't miss beat). Theres no kill switch ,as when I bought it come with a sawn ignition so just requires a screwdriver to turn on . I turn on and you hear as normal the faint "buzz" is that the power valve? but like I say no spark. Really sorry for being a pain (wish I was a skilled mechanic).

Firstly a big thankyou to "oldgitonabike" your a star, switch was faulty so cut and joined wires and superb it went through the gears without even a blip Can't tell you how chuffed I WAS. Gone back to it to show my lad and now I think I'm jinxed ,just won't start.Getting fuel ok ,but no spark,checked wires and they seem ok.Took coil and plug to his quad to try and sparks ok.Just don't have a clue (please remember I'm not a mechanic,so any advise in simplest term as possible please). Its got me so frustrated spent so many nights trying to find cure for other problem.So chuffed when sorted and now this. Please any help really appreciated.

Hi. What it is I bought this ages ago,to put into a fieldbike but as with most things just stood in shed,without unwrapping(time been in short supply,).So decided to try running before going any further. Is the switch like a plunger effect.What you've said makes a lot of sense "Your a star" I've been pulling my hair out trying to work it out.(wouldn't mind but I hadn't got much in the first place). I'll have a look tomorrow and let you know. Thanks ever so much,J.

Hi Everyone, Just wondered if anyone could help as I'm no expert.I have a dt125r which I have out of the bike.It runs sweet until I select a gear, everytime I select a gear it dies. I have kicked it, left in gear and everything moves freely but will not run.Put into neutral up she fires and sweet as a nut. I'm no mechanic so would appreciate any feedback. Thanks ,J.
