Just picked up a lovely mk2 TX200 in LH drive. 177
So after pulling out 5mm of washers, it’s down to just the 1 thin washer and still a bit close to the wind, so need to look elsewhere.

2 things I have noticed, 1 the top hat is quite long, and 2, just about every thread says replace the steel top hat with a plastic one on a 177. (Either of which I could make shorter)

So why do I need less mass if AA have designed it that way? The FAC version has a different top hat so it’s not that.

I’m specificly interested in the combined piston mass, as designed vs the tuners.
Who has the optimum solution to mass vs spring etc.


Thanks!
