Frequent backfiring at cruising RPM's

[1983lux]

Hey Guys,

I have a friend who drives a '79 GS1000. It tends to backfire a lot at cruising RPM's (3000RPMs) and definitely lacks power. The bike is all stock except for the cheap pod filters he put on it recently. Could these be the cause or is it more likely a timing issue?

P.S. if putting the stock airbox back in is a good idea, please advise on the easiest way to do this. I helped him take it out and it was a real bitch to do.

If timing is the way to go, could use a nice video or picture guide on how to do it properly.

Thanks!

When you changed to pods, did you rejet the carbs?

Timing is super easy to check, but it's likely the pods causing the problems. Gte decent pods and jet it, set the timing, and adjust the valves since they need it. In fact, catching up all the thirty year neglected maintenance would be a great idea.
