not very, they are known for making piston pins and pin bearings explode. maybe the cryoers could give you a bit more reliability.

if youve got money to burn like that git a saber kit, more power and more reliable.

i alway heard they had cool problems. with 2 stock radiators on it was still over heating.

Just out of curiousity, if they have that hard of a time cooling a 425, how do the sabertooth's stay cool? Wouldn't an aftermarket radiator (PWR, Afco) do fine?

no, the saber is designed to be bullet proof. though it will tare up a tranny in a hurry if yur running a worn out old stocker... actually i think the sabers run fine off of a stock radiator...

i was actually looking at a 250r on ebay with a psi cylinder on it. it had an aftermarket radiator and two inline coolers. i just wanted to know if they were reliable or not. i think i will just buy a 350 kit for my 250r instead. the 250r i was looking it was one of the best looking ones ive seen too. i really woulld like to have it but if it is not reliable i do not want it.
