Téma: Dual Weber 34 ICT's Tuning

Hello,

I'm having some interesting troubles with my carbs. I get this exhaust "popping" at about mid throttle. If I'm hanging out around 30-40 mph, it just seems to "pop" unless I'm into the throttle hard. I've tuned it here and there with a syncrometer and it just doesn't seem to matter. Also, where exactly on the syncrometer do I want to be at once it's "properly" tuned? I've looked and looked and can't seem to find any tech articles on what to do here. I had it running great last year, and now that the weather around here is cold one day and hot the next, I just can't seem to shoot the gap and lock down a tuneage. It's a stock 1600 DP with 009 dizzy. Any help would be GREATLY appreciated!

Please help

I didn't find the right solution from the internet.
