So I picked up a 2000 sv650 a few months ago and I’ve had to do some minor work to it but now I’m stuck. I was riding the other day and it just shut off and would turn over but wouldn’t actually start no matter what I did. So I swapped the plugs and sprayed some carb cleaner in the carbs through the air box and it started right up no problem. But I took it for a spin and as soon as I hit WOT the rear cylinder cut off. It’ll come on here and there but for the most part it’s been only running on the front cylinder. I took the air filter out and sprayed a little more carb cleaner in and it started up fine without the filter but as soon as I put the air filter back in, I’m back to a sv325. The spark is strong and prior to these issues it pulled like a bat out of hell so I’m lost. Do y’all have any ideas?
