Question about 2008 Aprilia SX 125
I just bought a brand new 2008 aprilia sx 125 and from day 1 problems. the bike is perfect when cold but after about 5 mins when it heats up it starts to splutter in the mid revs but then when it hits the power band it takes off . i brought it back to the shop i live in ireland by the way and they started saying that they got back to aprilia and they said that the climate here in ireland is too cold for the bike and will need new carberattor jets. the shop i bought it from have changed their story a few times but this sounds like a load of **** to me because irish climate is the same as englands climate and i have watched the sx on the internet and they seem fine no problems. if some1 could help me with this it would be great . thanks
Hi ....... The excuses you've been given might hold up either in Oz or tibet but as you say in Ireland it doesn't quite hold water.
Has anyone changed anything ? Pipe, airfilter, ignition ? The fact it takes off in the powerband show it's either not too bad or you've been luckey not to hole a piston. Try removing the spark plugs and note the colour, any colour other than a light tan is NOT correct and indicates fuel mixture as too lean/white (too much air) or rich/black (too much petrol). Too rich is preferable to too lean as being lean will hole a piston, burn out a valve or a partial/full seizure. Dependant on colour I'd then LOWER the circlip on the carb needle.
Let me know how you get on.
