What is this "T" thing i keep hearing about? does it make any more power, and can i buy just the T and not the whole hrc kit?

u can just drill the t out. its larger to let gases escape from underneath the piston more efficiently

It needs to be drilled to 25/64th’s. Be sure to take it in small increments, the drill bit will want to bite into the plastic and force it's way thru. There is a little bend in it and if the bit goes all the way thru, I'm sure it will break it.

I doubt it, but it should help the crankcase breath easier. The way I look at it is, Honda knows allot more about that motor than me. I'm sure they wouldn’t have wasted their time and money designing two different T's if it didn’t make some kind of difference. And plus it doesn’t cost anything to do.

No, just the one end. When you pull it out you will easily be able to see the restriction.
