DG rcm 2 exhaust/fmf power core 4/ jetting questions 03 warrior

[Johann1426]

Couple of questions. I have 03 yamaha warrior and purchased a dg rcm 2 exhaust (full exhaust) for a great deal (80$)

Now I have the option to buy a power core 4 slip on for (75$) which I'm going to do.

I want to do a main jet was thinking #150 main jet

But my other question is.... it's a mikuni btm sh 36 carb and I'm struggling to find which jet works (large hex, round etc. They say universal on bikebandit but unsure.

I have a basic air filter. Going to purchase an uni. And I have drilled holes in the air box cover for better flow low end is great but when I get 3/4 throttle in any gear it's struggles pretty good then will finally get some gas and go.

Any feed back would be great. Thanks guys
