Hi Guys Im Omar from the UK I have a Rzr 900 xp 2012 new to the Rzr owned for around 4 months having a few issues. Is the reason ive joined. My rzr is standard apart from full dragonfire racing by yoshimura exhaust (dual).

The issue im having with mine is when im casually cruising it runs a dream when i go to hit the throttle it feels as though its going to die out and backfires let go of the throttle immediately and it runs fine go to hit the throttle again and it does exactly the same only done this ever since i put the exhaust on also using NGK iridium plugs.

Any help would be massively appreciated.

Thanks Omar.
