Recently I put on a K&N filter onto my honda spree. The filter is really a breather for an engine, but i managed to get it to fit onto my Spree. Now it seems that it gets too much air. I tried the adjusting screw, but it didn't help. Should I replace the jet with a bigger one to offset the increased airflow??? I took the jet out and it had a 68 stamped on it. If I can get a bigger jet, would it be a 67 or a 69??? By the way at speeds above 25 my scooter bogs down...could this be another problem besides the jet??? It seemed to happen the same time I replaced the filter. Thanks
