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.

Okay will try that

Hi guys,

 

Thank you for your help, when i get home i will try that. Could i please have a bit of knowledge of why jump starting the bike will solve the problem?

Apologies if i came across rude earlier.

its cool man.. its cos a bike battery has to be at 12.6 volts to have enough power to crank the engine over and spark the plug.. if it is even just below 12.6 it hasn't got enough power to do all the things, thats why it is just turning it over and not sparking it too.

you could also try bump starting ur bike... what you wanna do really.. is disconnect the battery, fully charge it with a bike battery charger.. then leave it for 24 hours and check the voltage.. if it has lost charge your battery is fucked :)

thanks

But what seems wierd is when i got it it started, and then once getting it through the house, which did involve a bit of lifting the bike up, it stopped. First i thought it was the battery as that was quite low on power?, but even after a charge it needs to be  bump started?

 

All the best

you could bump start it on a flat battery cos u are effectively bypassing the starter motor.. what we are saying is basically that if the battery is below 12.6.. it wont start ur bike.. i know its weird that wen u got it it started and now it wont..its just process of elimination really.. if u charge ur battery and and it reads 12.6 volts and no less than 10 when cranking the bike over and it still wont start then it is a seperate issue.. but we cant go there until we eliminate the battery...at the moment mate.. it just sounds like ya battery is knackered.... i do know wat you are sayin, but u have to understand that charging your battery means nothing if it doesn't hold that charge... Also, when u say it isn't sparking,, have u had the plug out and held it against something metal like the cylinder head and checked this??? sorry if this seems patronising but i dont know if u know how to do this or not :)

I had the plug out yesterday and no spark was there, It seems pretty bizarre. If the battery turns out to be fine, what would the next plan of action be?,

did u earth the plug against metal when u tried it?? u could check the HT connections..if there isnt enough voltage in the battery though there wont be a spark... just try it with jump leads from a car battery to yours.. if it doesnt start then check for a spark like that too.. and let us know whats happenin pal

i can almost guarantee u that it is the battery that is at fault.. u have already said its like 2 volts below what it should be... answer my other questions as well.. like did u put the spark plug against the cylinder wen u were checking it for a spark.. cos if u didn't then there wont be a spark...
