Hi Matt, I have just stripped the carb out to fine it squeaky clean even still ran air through all the jet holes etc. Bike still has same problem!! Plug has a good spark but I will get a new one tomorrow. Checked all the hoses etc. and cant see anything amiss. If this was a car i would look to check the ignition timing but I have no idea how to do that or even if you can on the SR!!! This is very frustrating! Still, when I get the new plug tomorrow I will also get a tiny little screwdriver to play with the mixture while the bike is running. Sadly I odint have one small enough and dont really fancy taking the carb off every 5 seconds!! Thanks for your help, Tom

Hi, I have recently got a Yamaha SR 125 Custom (2002 model). The bike is in lovely condition but has recently started cutting out if I open the throttle quickly from idle (hot and cold). I took it for a good long run today, stopping and starting occasionally and the problem still persists. Any suggestions would be great to hear!! Many thanks, Tom
