So I installed a Woods WM8-22XE cam using the cam kit from Fuel Moto, changed out the stock intake manifold and throttle body to the 64mm SE combo, changed the stock fuel injectors to 5.5gms ones, and put in new spark plugs. When I went to go turn the bike on, it made a horrible cranking and popping noise and would not start. Any help on what could have gone wrong would be extremely helpful. I loaded a tune from Fuel Moto for all the new parts and tried the old tune too. Neither would help the bike start. Help!!!

 

Sounds horrible

 

I assume you double checked cam timing to the crank? By chance did you unhook the ACR's?

 

I double checked the timing and made sure the timing marks lined up before I buttoned everything up. I’m not sure what the ACR is but I made sure all connections were plugged back in too.

 

ACR (automatic compression release) are located at the top of the cylinder heads and plug into the harness along the frame backbone.

 

I used adjustable push rods from fuel moto so I didn’t have to go in from the top. I don’t think I could’ve unhooked that.

 

Plug wires crossed?

 

no chance of crossing them cause I took the whole module off without messing with the plug wires. And when I changed the plugs I only pulled off the side connected to the actual plugs.

 

The injector connectors crossed? Swap them see if that fixes it.
Adjustable Pushrods Have too many turns on them , were they able to spin free in the cuff of the lifter after adjusting them?

 

The backfire indicates you have fuel and ignition. I suggest you review the valve adjustment. Ensure you are adjusting the pushrods on the base circle of the camshafts on the correct cylinder and the settings are not too tight. Did you fill the lifters with oil and allow each lifter to bleed down?
