Hey does anyone out there know of any aftermarket piston kits for these machines? Can the 550 piston be used perhaps? Have looked into the 550 option, but Yamaha lists a different part number for the conrod, any help greatly appreciated!

from what ive been able to look into the xt/tt 500 used the same rod or better put the listings state they are the same part and available if it is any thing like my 83 tt600 i built the barrels rather interchangeable they just have different sleeve's fitted i ended up boring out a small barrel to fit cant remember if it was a 500 or 400 now was a hell of a lot smaller though (was 10 years ago )

No they are different
XT400 Bore x Stroke 87 х 67.2 mm
You should fine that the 92 XT400 "Artesia is the same size
& 550 Bore x Stroke 92 x 84mm

cheers for your info people... looks like Yamaha bits are the only option, the price of them has always been the killer for this bike, hence why everything else got done up instead
