I just got a 01 400ex and I put a timing chain in it and put it in time so I thought and got it all back together and I went start It and its backfiring out of the carb. Any help would be great.

 

Are you sure you had the TDC mark showing on the engine case, and the verified the valves were loose (not loaded) and the cam sprocket timing mark was lined up? almost sounds like you are 180 off if you are backfiring out the carb.

 

That's what I was thinking
When I get off work I am going to go try the timing agin.
Thanks for the info. This is my frist honda quad I have been around cars my whole life and I thought I can't to diffrent so I will try it. And when it did that i thought the same b/c my honda civic did the same thing

 

Moved this over to the Honda section.

Welcome to the forums.

 

I agree that it sounds like it is exactly 180 off.
