Question about 1985 Honda VT 500 C Shadow
I bought the bike about 2 months ago & it had sat covered in a garage for about a year & 1/2. I've replaced the battery, spark plugs, & I've tested the coils & they both test at 3.8 ohms. She will fire right up & run (actually sounds good), but for some reason that I can't figure out, the front cylinder exhaust/pipe isn't getting hot...I thought maybe a fuel problem, but I noticed when I pulled the plug from the front cylinder, I could smell gas, so I'm assuming it's not a fuel issue...HELP!!!!
You are Not getting spark to ur front cylinder. Swap your spark plug, if not then replace your front plug wire. if this is still not the problem ad you are sure the coil is good then look into the wire that gives the coil signal to fire

You need 3 things for normal engine operation 1. fuel - coming from carburetor (you have 2, one for each cylinder, gas is coming in to cyl. by vacum produce from 2 valves) so, run the bike for 5min, stop the enginea, the front spark must be wet, if it is not, you have dirty carburetor, you have to clean them, drain the fuel and take them of the engine,
2. you need spark - disconnect the sp. plugs, take them out, connect one, run the engine and check the spark (you have to take all 4 plugs out and first try front one-do this in darker space, you can not see spark on the sun)
3. air - this one is not that important for basic engine operation, for fine tuning - the small lines in the carburetor have to be clean and diaphragem must be whole.
