Prosport twang

[Tim33]

Prosport started to twang a little a few weeks ago so thought it may be time for a relube. I stripped, degreased and relubed using bisley moly grease and now it seems to be twanging more! I followed a relube guide posted on another forum (can remember which one as it was a google search result). I put grease on the spring, guide, and a tiny amount around the side of the piston seal, along with some around the delrin bearings.

Does anyone have any top tips besides buying a tuning kit?

Thanks in advance

I recently had the same issue and found that the rear guide was very loose, I got UK Neil to make me a delrin guide and top hat (sent him my spring for size) rebuilt and no twang.

Ive tried a welsh willy kit and a tinbum guide kit and standard prosport internals and all twang after around six months of use, i think the problem lies when the grease thins out, remember the lube isnt replenished say like a car engine where its pumped around, the grease you fit will eventually move away and thin out,everyone says a guide kit with a tight fitting guide will sort it but in truth its the fresh grease that quietens the twang,personlly i would get a tbt or tinbum guide kit as there only 20 quid but use the standard spring and a good quality grease sparingly applied and be prepared to relube every 5 to 6 tins of pellets, this is my findings and others may disagree

You can cut and fit a shim from a drinks can. Worked fine on mine. I used a coke tin which is aluminium and not ideal but I'm told that Carling is a steel can.

I must confess that I do find that tight guides help in this respect and I have a preference for using a sticky lube. Either Motul C4 (spray on and let set prior to re-assembly) or increasingly these days Finish Line Teflon grease , with either a thorough degrease and clean first is required. As always with springers the less is more approach is the way to go, too much sticky lube on the spring will also rob you of some power.

Yeah but my slack as a sausage in a shirt sleeve original steel guide would last the same 6 months with a fresh bisley grease, the same six months as any of the tight fitting delrin guides, iam just not convinced its a fix in my gun anyway,not wanting to argue just its that way

[Sake-san]

Yup, there is more than one way to tune / lube a springer!, for sure. But, we are now >7000 pellets through one TX which is demonstrating neither twang nor relube issues... And the delrin spring guide remains tight.

Iam glad yours is working ok for you matey

Hi lads,
I can highly recommend the Vortek tuning kits. I have been using them in nearly all of my springers and they're very good. No twang, no vibration, less noise, small deviation numbers, better accuracy,...
Reason I buy them is also that here in Austria or Germany we can't find such fine tuners like you have there. To put in some "cheaper" parts is always a case of luck and with the Vortek kits I never was wrong.

Here my AGs with those kits:
Model / cal. / kit / fpe / muzzle fps / SD / pellet / gr

TX200 HC / .177 / Vortek high ouput (FAC) / 14,2 / 785,9 / 4,1 / JSB EH / 10,34
HW80 / .22 / Vortek high output (FAC) / 20,29 / 860,0 / 6,5 / HN Baracuda green / 12,344
HW95 (sold) .22 / Vortek high output (FAC) / 16,52 / 712 / 5,4 / HN FTT / 14,66
I have a FAC-kit in my HW35 but it was too strong, so I collapsed one coil of the spring:
HW35 / .177 / Vortek / 11,0 / 691 / 4,8 / JSB EH / 10,34

Any 16 Joule / sub 12fpe - kit should work a treat in your AG.
I got them from here - see the link - and at the actual exchange rate not too expensive in GBP.
There is one avaible for the PS/TX:

VORTEK PG2 Tuning Kit AirArms TX200Mk3 16J.
Drop-in Tuning Kit für AirArms TX200, ProSport, BAM40 – 16 J.
Stückpreis: 89,00 EUR

Thanks for all the tips guys! Would you say using too much grease would make it twang as well? Also I will confess I only wiped off the AA grease with a rag and didn't use any white spirit or anything! Would this make a difference?
