Cheers for the suggestions, finally got it perfect after a bit more messing around. Looks like that M110 was dodgy, as I tried it in a mates gun and it was about similar to a M100. Weirdly, swapping from the bearing spring guide to a standard plain one only dropped the FPS by around 2-3, so put the bearing one back in, and now I'm running the M115 spring, with 2.5 coils chopped off, and took another tooth off the pickup side, so now it's at 305fps on 0.25s, whether on semi or full auto at 29 rps and doesn't miss a beat!

Done a bit of testing and threw in an M115 spring which seems to have sorted it!! Running a bit spicy now though, 350fps on 0.25s lol Would it be better to chop the spring a bit, or short stroke the sector gear a few more teeth?

Okay that's good then! Lol true, I was threw into the deep end when it comes to teching, bought my first "upgraded" lemon of gun a couple of months ago and have replaced everything bar the mosfet. What would be the best way of slowing down the pulling back of the tappet plate? Maybe I could try and run it without the delayer? Or maybe I can shave the tappet plate down slightly like in the pic attached? Guessing this will cause issues with the nozzle and feeding though.

Hi all, Currently have an issue, where in single fire, I'm getting around 290fps on 0.25s, but on full auto it drops to 270fps and 28 RPS which seems a bit low for my setup. 11.1V 1450mAH 25C Stock Tube LiPO G&G V2 gearbox Perun Hybrid V2 XT 200mm Barrel ZCI Rotary Plastic Hop Up Maple Leaf Macaron 60° with Omega nub 13:1 SHS Gears (Short stroked 2 off of pickup side) Warhead Base 27k ASG Ultimate Nozzle 21.2mm SHS / XT Cylinder and Piston Head Aluminium V2/V3 (Silent) XT M110 Spring FPS Softair Zero-Shock Carbon Fibre Piston with Steel Tooth Rack KoA 230% Tappet Plate Spring FPS Softair Carbon Fibre Reinforced Tappet Plate for Version 2 Gearboxes (Trimmed by 6mm) SHS Delayer Chip (Left side of it filed flat) Any idea what's causing this? I've already checked compression and the shimming, and both are fine. Could it possible be PME, or maybe I've trimmed the tappet plate too short or some other weird tappet timing issue? Cheers.
