i have the trinity pipe and its comes with it a main jet 190 so can i use this main jet for drag racing and top speed for long raiding and what a bout the heat is the engine will over heat or it will be the same as stock .

 

To get correct jetting, you'll have to install the new jet, then test it out by checking how it runs, sounds & how the plugs look. If you do a search for jetting, you'll find over a thousand posts on how to properly jet your machine. There is no one jet that will work for everyone.
