Stock 2011 TTR 50 I am essentially at sea level.
It bogs off the bottom. Terribly cold natured. I’ve heard of guys changing the pilot jet out? I hear this is a common issue? Thanks

Get the little bronze plug out of the air screw port. Allows access to the air screw. I think I ended up one step richer on the pilot also on a 2012.

Ten four. This is a 2012. I guess they didn’t make them in 2011? Either rate. I’ll give it whirl

Use a very small drill bit at very low speed on the plug. Once the bit "bites", rock it back and forth. The plug is not that tight. Don't go crazy and drill into the screw / carb.

I had an older GYT jet kit for the earlier model. I used the needle out of it, as it had more adjustment notches than the stock needle. If it is possible, you may lower the clip one notch on the needle to richen it up a bit.
