So I ordered a MMX "87 mm" throttle body and I would like to make a public service announcement about it. First of all, there is terrible pitting in the casting. The main reason for this post however, is that it DOES NOT MEASURE 87MM!. MMX's "87mm" throttle body, in fact measures.........80MM!. That's right!. It is the same diameter at the throttle blade as stock! Now we can argue all day about how much, if any, gain there is to a larger throttle body, but it doesn't help that they are out here scamming people with this $hi+! I thought perhaps I could gain something since I have their NSR stg 3 cam ( which I actually really like ), but obviously if the minor diameter is the same as stock, it's not going to pick up any power. I feel like I have been scammed. To make it worse, my only options are to pay for the shipping to return it or drive to the nearest shop in Martinsville, Va. Please do not make my mistake.
