Hi there, I have a SR250 with the same problem. The bike is driving perfectly, but only by full throttle, he blogs and hold in and I cannot find the problem. I only know that a friend of my told me that when the bike stood still for a couple of years the you have to replace the jet because he can be oxidated. I haven't try this jet, because i have to clean my carb first, my air filter is gone, and he's probably in my carb...

Hello Yamaha Onwners. My Name is koos, and I bought myself a secondhand SR250 SE from '84 for only 150 Euro's! A little carb problems but I will fix it, i hope Nice to know that there is a forum like this for talking about our bikes.
