Hi Joolstacho
It will be concentric 626/300 og 626/301, I have a pair
Main 160, jet 106, cut 3. I would like to compare with an other BSA but I find no single 250 or twin using them they use the 928. So then I compare with Triumf T100 and will start with
Main 160, jet 106, needle pos 1 or 2 and cut 3.
The 928 is probably a better choice there more to compare.
