I've heard of other people using them... I've contacted them in the past and found them helpful and professional, although they didn't do the manifold I wanted... Might help if you actually say which manifold you're thinking of buying...
I have one fitted - much much better than mangoletsi which is what i sent back to euro carb to get a refund then i got the rowland one - very cheap too - no duty or anything to pay and they are seriously helpful... depending on linkage you may have to trim middle brace .... hoke out my thread in readers rides stacks of info there on the issue - also on swan neck water outlet...
