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.

I used a multi-meter on the battery, and its an optical one, so you can't tell exactly but it was deffo over 12.

I do appreciate everyones help, but you posting ignorant comments like that doesn't help anyone. The battery is out of the question atm, The hunch from a mate who done motorcycle mechanics for 2 years, reckons its a problem with the coil.

Er

what exactly is an "optical" multimeter??

I've had umpteen meters over the years, analogue and digital, but I've yet to come across an optical one?

Anyhow, assuming your battery to be ok, (have you tried substituting it with a known good one?) it'd be a good idea to check the wiring through your ignition system for corrosion / breaks / chafing before you throw money on random parts - otherwise you risk buying a new part and having the same problem. Heat, vibration and chemical attack (salt etc from the road) can wreak havoc with electrical systems (not familiar with your bike, but if it has an HT lead to the plug, replace that at the same time).

For what it costs, and you say its not sparking, it might well be worth trying a new plug(s) (how long has that one/s been in?).

Hope that helps.

joec104,

Are you saying the engine spins with the starter?
Can you smell fuel after cranking?
Is there enough fuel in the tank?
How long did it run for when you first tried it?

Check your kill switch, choke and fuel tap positions.
Try it with the stand up, and try it with the clutch lever pulled in (they have safety switches which can go wrong).

Check the fuses.

it could be a problem with the coil.. check for a voltage reading there when u try and start the bike..

Hi,

Sorry for sounding ignorant to your help before.

I had tried it with clutch in, double checked kill switch and choke. The bike turnsover but its just not sparking. But when i turn the throttle whilst trying to start it, the bike makes a whining noise?

Yeah, thats the multimeter.

I will try to bump start it at the weekend, as the bike is in the back garden currently, as i won't be riding it for a bit.  Okay sure I will do, where abouts would the coil be mate?

 

regards

Bump starting will give u the best idea i reckon.. im not 100% sure where the coil is on ur bike, i have never had one..  just follow the H.T lead from the plug cap to a little cylinder and thats it.... check for a voltage reading there when u press the ignition button..

Check your ignition fuse.

(Although I'm trying to think whether that would prevent the starter from turning also? Maybe not. Easy enough to check anyway.)

 Can you smell fuel after cranking? Is there enough fuel in the tank?

Are you flooding it, or alternatively not giving it enough choke?
