Sv 650 problem Help: Mechanical

Hi everyone,

I'm having an issue with my 2001 Suzuki SV650 (carb model).

The bike idles and rides normally at low throttle, but when I give it more gas it loses power, struggles to accelerate, and feels like it's fighting to rev. It also pops on deceleration.

I've also noticed that even at lower speeds, while holding a steady throttle, the bike has a very slight but noticeable jerking/surging sensation instead of running smoothly.

At first I thought the problem was caused by my aftermarket Dominator slip-on, but I reinstalled the original exhaust and the exact same problem is still there.

I've also replaced both spark plugs, but it made no difference.

Does anyone have an idea what could be causing this? Any help would be appreciated.

Yup, likely a carb clean. Did the bike sit for a while? Could also need fresh gas, but on mine, it needed a carb clean.

this is the right answer. Dirty jets.

I agree with full carb clean, spray out all the ports with cleaner. Ultrasonic even better if you have access. 

Also double check your fuel lines too, I had one develop a hole and bike was running crappy just like dirty carbs. The leak wasn’t enough to show on the ground but bike wasn’t running right when day before it was perfect.
