no spark!!!!!!!!!!!
 

hi been trying to start my bike and it wont start. there is no spark at all with a new and old spark plug. tested for continuity on most of the wiring loom. coil seems to be ok and also the killswitch. using a brand new ooracing cdi so cant see that been nackerd. also new inner rotor fitted about 2 month ago. any suggestions please?

Im in the same situaton as you atm fitting a 140 lifan engine. Im next to change the ignition coil, cdi & if i have to the stator too. Also will give the pickup a clean. Im taking small steps before I do anything like the stator ect... I know my problem is electrical.

Re: no spark!!!!!!!!!!!
 

yeah i no this problem is definately electrical but where do you start. i found a wiring diagram but aint had a propper look at it yet.i had a guy fit a new inner rotor as my mate managed to snap off the pick up. this guy has crimped the wires together but not very well. hopefully by soldering the joints together i will get a better connection and hopefully a spark.

All I know is that the engine I have was running before sent to me and now it dont want to run. My wiring is correct so Im sure it can only be something going on with the pick up for me. But Im to check everything anyway.

yeah good call. on mine it is only a two month old rotor kit so cant see it been that but i aint too sure. cant guarantee the quality of this guys workmanship or parts that he gets. hoping it is just his terminations on the new wires. cant understand it though cause one minute it worked fine then i operated the stop button to kill the engine then 2 mins later i tried to start it and it wouldn't start or get a spark?:confused:

Re: no spark!!!!!!!!!!!
 

sounds like the killswitch all together. Take off the killswitch as a test then start the bike. To kill it all you need to do is pull the ignition coil off the spark plug. If all is running happy then you will have to get yourself another killswitch. I dont have a killswitch on my bike as I got rid of it completely when it was causing me problems, to kill mine i use the igntion barrol which overously u dont have.

yeah i will try that tmoz. think i have already tried it tbh but i will give it another go.

update: keeping the story short

Cleaned the stator& pickup. It fired up, wnet out for a blip, cut out on me a few times, cleaned it again, started up, bliped out done it again, got the van got me back to the garage, after that time elapsed just kicked it over 1st time and it started. Was adjusting the carb mixture then all a sudden it died. We had tried & placed everything electrical with spare parts i had and nothings wrong with them.

Conclusion: Everytime the stator gets hot the bike dies. A new stator is the only thing left for me to try out, it has to be that, everything else has been checked.

summary: Bloody hell I LOVE 140 Lifan ! :). Great when its going.
