Hello everyone,
I'm new on the forum.
I'm a classic british bike enthousiast since a long time and always wanted to have a BSA A10 as I find this bike lovely !
Well, my dream came true and just bought one that I want to put in RGS configuration. I have find this very nice forum with lots of good infos !
Here is the story.
I have take off the engine, and rebuilt the bottom, and cylinder head. Looking actually for a good gearbox, but in standard configuration as the RRT2 is hard
to have and difficult to ride the bike everyday with that type of gearbox.
When I take off the engine, the pistons and barrels were in +.080 but in very good condition, so I decided just to change the rings that I found quite easely.
GPM pistons in 72 mm were fitted, nice pistons. But when I decided to refit the pistons, a piston felt off my hands and went on the floor, my mistake !
The piston is damage and no more good, (small crack) so I 'm good to find one or buy a pair.
I have made lots of research on the web, but it is impossible to have a GPM in 72 mm.
I have called Cake street classics, but no one answer, probably out, I will try this afternoon. I have notice that he sells wiseco pistons in 72mm but maybe he doesn't have anymore..., I hope he has some.
I have also find that JP's sells some in 72 mm , but in 7:25.1 ratio, a bit low, I would prefer a higher ratio, like 8:5.1
Any suggestions, advices ?
Thanks a lot for your answer.
