fwb sport info please

[hollow-point]

could any of you knowledgable guys tell me a few things about the fwb sports. just bought a 124 and 127 and would like to get them to be at there best.

what is standard length/ coil thicknes and number of coils on a standard spring for the 124 and 127? do they both have different springs

one has a leather breech seal. i think its the 124 but will check. can these be replaced with synthetic seals? are the 124 and 127 the same size seals?

should there be a shim on either side of the breech block? one side is has a metal face the other has a rubber bush

the trigger is touching on the stock slighlty can it be stripped and shimmed to stop it doing this as it is over to one side slightly

also do any tuners beside maccari do kits for these and are they worth buying? or even just a shorter thicker spring to lessen pre load and a different piston seal? or can they be made smooth with the original parts

havent had chance to strip them yet but will be doing very soon as i do with all guns i buy.

sorry for all the questions( reads more like an essay) and thanks in and thanks in advance for the answers

THIS may be of use.

The shims should be dished and flat and Ive never seen a 'Sport with a leather piston seal.

could be that is is just a discoloured standard one. just had a quick inspection and it looked like leather. probably just me being a fool. mine has a metal on one side dished on the other i think. what are these made out of?

Dave Hall at Shotmaster tuning did a tune on my 124 and it came back
a different gun... fantastic

ive emailed him but he hasnt got back to me yet has he stopped tuning? does he sell the kits for the owner to fit themselves

Phone Dave on his landline between 9am and 5pm weekdays, he is still tuning but has a habit of not reading e-mails and forum posts. He doesn't market the kits he designed, but will tell you who does his kits now.
If you want your FWB's to operate at optimum, get them to Dave, best in the business with springers in my opinion!
You will find his tel.no. on his web page. Shotmastertuning.co.uk

Having just put a Maccari kit in mine it has transformed it. The standard spring has hellish preload & accompanying recoil, its now much smoother.

Maccari kits rock (buy a pot of the tar and lube at the same time). Sports are on the whole are easy to work on (spring compressor aside) and not too much to do. Don't know his work but I'm sure Dave will do a lovely job. Either way worth doing and then you will have a lovely smooth machine.

Woodwork wise I've yet to see a stripped stock done well. I'm sure there is a way and would be interested if anyone has made one look really good. After market ones can be found but are quite expensive compared to the rifle.

The steel holds a lovely blue and can be revived as good as new with a reblue.

Triggers vary a bit and can be improve a little but need someone who knows what they are doing and not every one does. I've never had a really bad one and after a good clean and relube have always come out fine.

Enjoy.

the standard spring has 40 coils and is 12 1/2 inches long
never seen one with leather seals / they are synthetic
i myself prefer the original spring as the cocking effort goes up with shorter stiffer ones
if the trigger is ally it could have been bent at some point during a clumsy strip down
strangely i have never seen a broken plastic trigger but a few ally ones
good luck with the sports / best springers ever made i think

When Dave tuned mine he got it running at 11.4fp with a 27 coil spring!!
