I have a Powroll an 11:1, 5mm big bore kit in my 350X. Bought it back in 2013 and the bike runs great to this day. Lately, I've been considering stockpiling certain parts, and replacement parts for this kit is one of them.
Since they are no more, did anyone buy nos from them? Or have any additional info?
I see Mickey has a 502cc kit, but honestly it's too much for my needs.
