Hi,

Im currently building a 2056 setup with 96mm biral AA performance pistons. Is anyone else running into the problem of the bottom tins around the pistons not fitting?

i have included a couple photos below. The bottom tin hits the fins on the pistons. Maybe i can go with out them? Everything else fits.. Thanks in advance

Trim if you have to, but DO NOT run without them. Very important for guiding the air flow around the cylinders.

I was a bit flummoxed when I ran into the same issue. I finally found a thread here where someone else mentioned it. Apparently it is a known issue with the 2056 builds, but I hadn't seen anything about it previously.

Yes, grind or cut that piece of tin to fit.

Yes, I did a thread on this about 3 years ago. The biral cylinder fins are much larger than stock cast iron.

I just bent the small area that hits out of the way so they fit right.

Anyone using AA Birals 96mm cylinders with KB stroker pistons in a 2270 configuration?

Phew, I almost decided to leave them out. Thank you guys! I'll def trim those pieces down.

Cheers!
