Cam chain timing (400ex)
I picked up a 2005 400ex for cheap because it didn't run, no compression. Ended up being a cracked valve seat. Sent the jug and head out, put it back together with a new weisco 11:1 piston and a white brothers WB1498 cam off ebay. Also rebuilt the carb. During the rebuild, the cam chain was very slack and rattled around in the crankcase freely (more on this later). i put the whole thing back together, and noticed during the cam install that the timing lines were just a little off of square from the top of the head. Didn't think too much of it, put it all back together, and now it wont run...
I am running a full air box with snorkel, k&n, and a new FMF powercore4. Jetted at 165/42, 3 turns out. No adjustable needle
If i hit the accelerator pump before cranking a couple times, i can get it to sputter, and if i hit the throttle just right, i can get it to run, just not idle, it immediately dies, but if i hold it, it will stay running high, so it is drawing a vacuum properly from what i can tell
So after reading and reading, i decided a stage1 hotcam is going to better suit my terrain (tighter woods), so i have the cam torn out, and was wondering if the cam chain can skip a tooth on the crank to affect timing? Or did i just adjust my valves wrong?
Open to any ideas, i can grab a shot of the cam timing mark if that could be useful
