i know this question has probobly been asked a million times, but i need to ask it again. i have an extreme problem with bogging in first gear and in neutral. I ride a 2005 yamaha ttr 125 four stroke. I had a problem similar to this before, but it was not near as severe. Before i just re-aligned the valves and all was good, and im wondering if it will fix the problem again. The bike bogs so bad in first that i constantly have to check to make sure im in the right gear. if anyone has some advice i really could use the help.

The pilot screw can make quite a difference. If that doesn't fix the problem, open up the carb and clean it. Adjust the pilot screw again. If that still doesn't fix it, fatten up the pilot jet and maybe lower the clip on the throttle needle a position. I can make my TT225 bog quite badly just by moving the pilot screw in and out a turn.
