Aprilla rs125 Won't start.

Hi everyone,

Im new to this forum and biking for that matter, put i will give it a go.

I bought an aprilla a few weeks ago and it started up fine, however upon bringin it through the house, it now does not start. At the time the battery was low, I have charged the battery and have cleaned/dried the spark plug. The bike is not sparking, I am wondering what may be the matter with it? Since that last time it started it was only a few minutes and a trip through the house to the garden till it did not start? Advice need thanks in advance.

If its the coil, would the bike still be able to be bump started?

 

Cheers Joe

nope cos its the coil that provides the spark.. but... you really should try and bump start it.. i think anyway.. its fool proof. did u try jump leads from a donor battery by the way?? i know u dont think its your battery.. but u should really try. it could turn out to be the coil but its funny how it went so quickly... you should check the spark plug cap has a good connection into the HT lead too.. sometimes they can corrode inside and give u a shit connection.. especially if u have been lugging the bike about a bit like u said u have...

Fuses.

"If the ignition fuse had gone it would be dead at the button."

Rob, I don't think that's true for all bikes and I think the RS125 is one such. I could be wrong. It wouldn't take a minute to check them though.

Joe, you're missing the point a bit. The fella's have suggested a jump start because if it works you'll know your battery is almost certainly knackered.

On the other hand a bump start wouldn't involve the starter (obviously), so if that worked you'd know you had sparks a least and that your starter or starter circuit was the culprit.

It's a process of elimination. Good luck!

Thank you for all of your responses,

I will take a look at the bike at the weekend, Due to the fact by the time i get home from work its pitch black. But yeah i will check if any cables have come loose, which could be a quite likely suspect, once again thank you and will let you know.

LOL... instead of looking for loose cables.. try a donor battery.. try and jump start it... check for a multi meter reading at the coil connection, check your ignition fuse hasn't gone like James says.. we will stop giving advice if u just keep ignoring it.
