Question about 2002 Yamaha TT-R 225
Usually this indicates a lean fuel/ait mixture. Remove the main jet and note the number stamped on it. Go to your dealer and give him the VIN from the frame. From that number he can tell you exactly what year, model and engine size you have. Now ask them to check the stock main jet number. If different than what is in the bike then get the stock jet. Check the manifold between the carb and cylinder. If any rubber seals or hoses are hard, then replace them. This will eliminate air leaks on the intake leaning the mix. The image below is for a 1995 model. On the carb main jet and nozzle (in red), make sure they are very clean inside and out.

??. has this bike been rebuilt. I worked on a older honda once that had been locked up (hydraulic - engine full of gas) and they tried to pull it off with another bike.. when it was rebuilt.. it ran until the exhaust got RED HOT... in the end..(after ALOT of trouble shooting) the problem ended up being a BENT CONNECTING ROD!!. Once it was replaced, the problem went away!!
CRAZY hard to find!!
