My bike idles ok but when i give it a little throttle she stalls. I had the bike in storage the past year and would start it every other month. I also drained and replaced the gas at this time. Bike ran fine for 10 months but the last time I started it this problem occurred. I just changed the fuel filter and she appears to be receiving gas. Whenever I touch the throttle she stalls. I am hoping it is not a clogged main jet. Any ideas? Thanks
