I recently bought a 70mm bbk throttle body and for some reason it seems to have the wrong linkage. It will not open all the way, in fact it barely opens at all. It seems like the spring on the throttle cable is too big. The spring is fully compressed when the throttle body is only slighty open causing it to stop opening all together. I followed all instructions and have been stumped for the last hour and a half. Please I need help, if somebody has installed one of these before and had the same problem, i would like to know how they solved it. Thankyou in advance for any help.
