Just rebuilt the top end on an 07' M1K, everything went smooth until now. I can't seem to get the mag cylinder to fire. Checked compression, fresh plugs, checked spark and nothing. Any ideas on what else I can check???:confused:
 
If all those work the only thing left is fuel. tap on the injector. do the plugs look wet. Might be something to do with reeds. there is a way to check the injectors but I'm not a 100% sure so I will let someone else tell you. What mods do you have. If you run a bd box check the injector connection.
 
I have an intake and Y-Pipe. No BD Box. The plugs were soaked on the Mag side, then I replaced them. I then fired it back up on a stand and ran it at engagement RPMs hoping it would fire......Nothing
 
The plug wires will wear through from vibration on the head and cause a short sometimes. Have you pulled the plugs reinsert them in the wire and pull the sled over to try and get the gas out of the cylinder. sounds like a stuck injector maybe. Do you have a fuel pressure regulator. might be a good idea to check fuel pressure.
 
As wyoboy suggested, check fuel or spark. Plugs wet, not fuel. Install a plug leaned up against the motor and pull over to check for spark. Still can't figure it out. Check all factory wiring harness plug ins. Something is probably unplugged. Kill swith and key is off, right.
