So I am rebuilding the top end on my Blaster parts bike. I need to bore the cylinder, so its time to buy a 67mm piston, if i go online i see a bunch of different kits, I have a Namura in my running blaster currently and honestly its great, what are some thought on Weisco, stock, Naumra, Pro X or I saw Vitos the 5hp piston, has anyone used it? Honestly idk if i believe it, any thoughts? I know I will prob open a can of worms and get a bunch of different opinions, but would like to hear opinions and experiences, honestly I bought a used engine a while back and it had a crack Weisco in it and I mean it was cracked pretty bad so I truly feel like any pisiton has a potential for failure. Thank you for your help =)
