i originally bought yellaterra's because they had a great reputation everyone talked so great about them..... well i guess things have changed
in late july after about 8k miles i had a catastrophic rocker failure
now let me start by saying the install was 100% correct and i am not to afraid
admit that i was spraying the motor with a 100 shot (but it did not fail during a N20 run) i was running 450psi spring pressure on some comp 926 springs with Ti retainers on afr heads.
well this rocker failure has trashed every bearing in my motor and cost me the rotating assembly..
jim orignally told me they would replace the broken rockers he also made mention the the yella terra's are only meant to hold 400 psi of spring pressure even though i cant find this much needed important info anywhere on his site.. he believes this is what snapped the rocker in 2
25 emails and 5 months later i still have no replacement and responses from jim and doug are getting fewer and further between...
i would not recommend the purchase of this product they will not hold up
picture is worth a 1000 words and a engine rebuild

also had friend who had a pair break within 50 miles of install
