esr 430 cylinder kit

[sikadelic]

just saw esr has 430 cylinder kits. anyone out there running one of these? pros? cons? comments?

pretty sure its a drag only motor and is not reliable. It also requires case boring and a min of 5mm stroker crank and suggest an 8mm so its Def not an everyday rider.

if you want a cylinder that big get a puma,
mines 443cc with a 6mm stroke
