Thanks for the replies, I was suspecting the reeds because I've tried just about everything else. But in 5 - 6 years on the forums I've never seen any threads about bad reeds (other than broken).My most recent 'decent' tuning was...Stock motor3rd over bore w/~500 miles~120psi each cylinderSpecII pipes10mm reed spacer (between barrel and reed cage)RZ boots and crossoverDave F carbs, 5/32" drilled air jet, 27.5 Pilots, 200 mains, needle clip on #3 with a shim (half way between 3 & 4)K&N Y-bootNGK Iridium spark plugs (stock heat range)Basically it ran very good, I could putter at a walking speed and it would pull clean and strong to 8K+rpm, but at a stop light or almost closed throttle I'd get the rrrPOPrrPOPrrrrrPOP, etc....(maybe I'm expecting too much from a 30 year old machine)I guess I'll try swapping ignition parts left to right and see if it's not weak electrics at low speed, at 2K rpm I get ~14V at the battery and it never goes flat when it sits a few weeks.Then I'll try just swapping the reed blocks left to right to see if the POP POP POP moves also.I'm stumped, and getting frustrated, maybe all RD do the PO POP POP thing, this is the only one I have any experience with.Thanks
