delt direct with burton not ctm buddy
guy i spoke to was very very helpful & understanding & this issue should'nt of happened if sales people asked the right questions & got the right answers before sending pistons off for machining not just assuming that i was using a c.vh head
maybe thats the cause of you rattle as well matey
yeah would be good idea to get together for a group buy,let me know what info you find out regarding replacements
spoke to ian Howell the other day do me a set of arias forged to my spec for approx £550ish,not sure how fast he can get a set machined though!
trying to look on web search for other types & makers,not much luck the moment
they did offer me a new set but i am scared of this problem rearing it ugly head again so going to take money & run me thinks
