Hey! I’ve had my kfx for almost 3 years. Rebuilt top end spring of last year then the rod bearing went out. Rebuilt the bottom end with all hot rods bearings and a hot rods +3mm rod and crank. I have an athena cylinder and wiseco piston. Stage 2 cams and kibblewhite black diamond valves. Wrapping up the rebuilt now and it cranks a time or 2 then stops. Tested the battery and turned out it was bad. Replaced it and still had the issue. Cleaned all my connections. (battery terminals, starter solenoid, and starter) issue is still there. I got my starter warrantied being it still didn’t crank that quick with no spark plug. Put the new starter in and issue STILL will not go away. I took my stator casing off to see if I put something together wrong. I don’t see anything out of place or incorrectly installed. I have not taken the fly wheel off yet but i plan of it to see if it’s something behind there. I would appreciate if someone on here knew what the issue is or could be. I’m out of thoughts about what it could be. I haven’t seen any threads on this exact issue.
