I have had my grizz snorkeled for a while now, and like you said I did end up putting a jet-kit in it, and after putting it in it runs great. BUT I did have one problem after that. Before the jet-kit it ran fine, but was extremely hard to start, and the jet-kit fixed that. But after the jet-kit when I take off it coughs and stumbles until the throttle is pressed enough then it runs fine. I was wondering why it does this, and want to make it stop. I got to thinking and my buddy said he thought it was bc the engine is getting more air+gas which is making more exhaust. Would putting a hmf pipe on it stop this from happening? If not what can I do?
I fixed my problem, my air filter was missing a huge chunk if foam which was allowing dirty air to get into the carb, which was causing the problems I was having. One thing i did notice the jet-kit gave me about a 10mph increase from 41mph to 51mph
