Bore Up Kit is a slightly wider cylinder, to be honest not really worth the time or money on it (my opinion ;) ), if you really want to persue it can you buy the piston and cylinder head from RS http://www.rodastjarnan.com/airsoft/shs-pistonghuvud-bore-up-35752 http://www.rodastjarnan.com/airsoft/de...

I always use balance charge, normal charge is meant to be used for batteries without a balance lead, also quick charge wont charge your batteries too 100% capacity compared to balance charge

You could try a sector gear delay chip

Ahh oh then you'll need L85/SVD/SR25 gears you can pick up some SHS ones cheap on ebay

Maybe cut off the second tooth and fix the AoE ? you do have it in the correct runners for the piston ?

True individuals have questioned the reset time, but I've never seen any hard data to actually confirm it, mind I fire only ever semi so in my case it'll be negligible Mind after googlefooing it looks like Sorbo resets after 9ms +/- according to their data sheet, even firing 50 rounds per second you...

Unless you mean to place it behind piston head and the piston itself ? :D However you are moving the piston head forward and will still lose the same volume, your most than likely firing too much air and the loss of volume won't be noticed unless your cylinder is matched a 100% to your barrel length...

^^ not true at all mate, doesn't matter if you place it on the cylinder head or the pistonhead you will loose the same volume in the cylinder
