Hey im new to this page but im trying to figureout a couple problems with my grizz. When i rev it up and left off she backfires realy fkin loud and shoots a huge flame. I have no leaks in my intake system and a new flange from throttle body to the head. (Old one ripped cause bad motor mounts). Anyone wanna recommend something for me to try?? Valves?

It's always good to adjust the valves if they have not been adjust for 2-3000 miles.
Should add a new spark plug.

Is your air filter clean and "properly" oiled so as not restricting air flow? Is your exhaust system secure and not leaking?
If you had bad motor mounts you could've tweaked your exhaust system.

I have a crack in my header pipe i found today. I have a tuner and messed with it to get her running right for now, im thinking there will be a full hmf system on it here in a little bit lol
