Have new zenith carburetor and new gas tank put on this year! I keep bike in the garage, will not start, i will push it out side in the sun for about 30min and it will start right up! I have replaced the spark coil, plugs, plug wires and VEO switch! Still same problem. Does anyone have any ideas on my next step! Also has anyone used sea foam additive to your gas? Was a suggestion i got!
