400ex won't run
Hi everyone,
New to the forum here. I recently have recieved a 2006 trx400ex. It was sitting for a year and a half. Wouldn't start or crank when I recieved it. I installed new battery. New namura 11:1 piston. New rocker arms. The works. Cleaned carb. Fuel lines. Cleaned Vacuum line. No air filter. Replaced sheared woodruff key. (That was a piece of work! 5 minutes max)
I have been working non stop on this machine and couldn't figure out what was wrong. I finally found the fuse was my problem. I replaced with 30amp fuse. Now it will turn over but won't start. I adjusted valves. .12 exhaust and .10 intake. Cleaned carb again to make sure. I finally had it turning over and firing. Now when I try to give it gas and start it, it pops and backfires through carb and exhaust. I have about 110 hours of work on this machine. Has HMF pipe. Only aftermarket on it. I need help. My family wants to go to LBL when it starts getting warm! Any help is appreciated. Thanks

When your valves are out of adjustment it makes the motor not want to start easy.
