back fireing help

[malpass]

just rebuilt my top end it is runing good but it has back fired a few time any idea why

[brianposs]

Check for a sheared key, what size jet in your carb? what kind of mods?

[wrench man]

If it's on deceleration you're maybe just a whisker rich, and you have an exhaust leak.
