Aprilia RS125

[Scruff82]

Hi to all,

My aprilia rs can only described as c"ck tease. The little slapper keeps cuttin out mid drive and i reckon i have flooded the spark plug.

Anyone else having problems with their RS?

Cheers

No mate, I think you must be the only one with problems with an rs 125
I've spend a grand on fixing it to give you some perspective

What plug you running
theres the common issue with RS's needing certain plugs to your riding style..


and hows the bike
Restricted to 14.6bhp?
Derestricted to 33bhp?

i know little about bikes, so maybe the rs was a bad idea.

im not sure what plug im using at the moment, im going to buy some today and see what happens. Browsing this site says anything from a br8 to br10?

its deristricted,

[tutton]

I think
br8-restricted
br9-deres more town riding
br10-deres for fast riding, will run shit at tickover and wont idle and that.

The first thing you should do is get a Haynes manual. They are worth every penny and that's how I got through removing and fitting the whole engine with no previous experience. And the bike actually works

yup. my RS is dead after a year of riding. Its a 2007 bike

electrics are shite, i have no speedo, no rev counter, no indicators. Needs a new top end, needs a new clutch, powervalve needs looking at. but on the otherhand it is a brill bike to have some fun on.

its quite silly tbh. im going to take it off the road soon and chuck a new engine into it. its a shame as when it is running well it is a brilliant bike.

I must have got a good one.

2500km on it and touch wood not skipped a beat. Last 1000 at full power.

But it is run on the best oil and fuel and always warmed and ridden gently for a few miles. Don't get me wrong it does get ragged once warm but only when warm.

Defo buy a haynes. Worth it's weight in gold.

The rs (and mito) need regular piston rings to keep them reliable, if im not mistaken they are supposed to have new rings every 5000 miles as part of the service.

Nothing wrong with the bikes, plenty wrong with the owners. They make over 250bhp/litre, so they need some looking after.

Keith has owned RS125s for year and has little trouble with them. He knows how to look after bikes.

I fancy an early mito. They look fun.

I know little about bikes and I know I haven't helped my cause by thrashin it.

I've taken off the spark plug, and there is a lot of liquid where the spark plugs go, firstly should this be ok? Secondly for those like me who know nothing about bikes, do not put a lighter over the whole where the spark plug goes!!! BANG!!

The threads look damaged so i might have further spending money problems on the bike.

i have also just bought a rs and am having the same problem, splattering, wet spark plug hole. i'm assuming its getting 2 much gas and is fooding, once it clears throw it has heaps of power up top. 1 tip i have for you is to ride the accurate throw, dont just pin it and wait 4 the motor 2 catch up cos thats when yr pushing 2 much gas in and will stutter
