Just brought home the 525xc. It has a small bog when you first hit the gas. If you push the throttle nice and slow it comes on fine. But when you give it full throttle from an idle it bogs. Also it wants to backfire when you let of the gas at high rpm's. For this I raised the clip 1 notch and it seems better but I only have one notch left. When it backfires when you let off the gas I think this is from to much gas and it burns off real quick. Is this correct. My elevation is 3900 ft. Any help would be appreciated.
Thanks
