[QUOTE="RazMan, post: 225912, member: 6030"] The head misalignment was something I was aware of because these kits are designed for the GL1000/1100 which have larger inlet ports. I am either going to fit GL1000 heads or I might even try tapering the GL1200 inlets to mate with the manifolds. Reading through Randakk's extensive instructions (which just ooze with 'supreme being'), they say that " In the interest of creating a bit of turbulence to aid even fuel mixtures, these intakes have not been overly finished or polished" That's quite an understatement in my book - these are very inconsistent when comparing ports and I seriously doubt that 'even fuel mixtures' are remotely achievable without some serious repair work, in fact I doubt that any kind of match is possible or practical. The ports are all out of whack - one manifold is totally different to the other. Here is a very crude example to demonstrate ( I just bolted them up to the heads and marked around the inside of the inlet ports with a sharpie) but it shows how they are offset differently. One manifold even has gaps in the welds - did they run out of TIG wire or something? 'even fuel mixtures' ?? Pah! [/QUOTE]
