Just because I like getting all my ducks in a row before poking at things.
In the DC area it has rained about 3-4 inches in the past two days. In between storms to avoid parking tickets ("street cleaning" in this town) I fired up the bike to move it. As I backed off the choke it changed tune as if I had the petcock on "off". It stayed at the right rpms but had a sluggish throttle response. Drove it 3 blocks and it was acting like I was shifting at too low an rpm and it was making an odd almost backfire noise occasionally as if it was under water. I left it on when I parked and the front cylinder exhaust wasn't hot and I could faintly smell some gas.
This makes me think I either have a stuck float or no spark. Since I haven't messed with these things yet I just had some dopey questions:
To check for spark, all I would need to do is remove a plug, ground it against the engine case and hit the start button right? Preferably not zapping myself.
For a float, I should drain the front carb bowl via screw, find the line from the petcock that goes to the front carb and put some seafoam in there over night, drain, and give it a go. How much seafoam would folks recommend/which hose?
I am leaning towards spark since it rained a lot and the wires prob haven't been changed ever (1994/29k miles).
Thanks for the help!
