Hi Folks,

I have a TM OK Senior engine 2020 (prob S2) but I am strugling to find some piston measures for my TM. I used to buy Piston SKU tm10243.xx

On the other hand I am finding all measures for the new TM Pistons OK Senior S3 sku tm10245.xx

Does anyone know if there was a change in the piston design for the new TM OK Senior S3 engines? Can I buy S3 Pistons to use in my TM Senior OK previous engine generarion?
As far as I noticed the new S3 Senior pistons are available in the same measures, degrees. (^4), etc as the previous generations.

Any help is very much appreciated.
