    GS Oil Cooler mounting hole dimension?

    The Lockhart oil cooler is bolted between the front frame downtubes . . . . does anyone know what that frame center to center hole dimension is on the GS 750, 850, 1000 or 1100? (I believe they are all the same). I ask because I won a Fleabay Lockhart 500 oil cooler that was installed on a Yamaha Radian 600.

    TIA

      I dont know for 750(8v),850,1000, but I have a couple 1100's around that if the weather breaks (it is in the mid 50's tonite) I could brave the backyard and see>

              100mm exactly. If your talking about the 8mm holes that sit between the steering head and the exhaust headers

                          I tried to measure the bolt spacing on the frame. The 81GS750E has a set of holes at 4". The GS1100ED was hard to get at because teh collers are mounted in front. The m,ount bolts to teh fraem then the coller mounts to the bracket.
                          I think the GS1100 spacing is about 2 1/2". But there is yet another set of holes you can use based on this bracket I made from a 550 cooler bracket. The widest set of holes are for the cooler. The inner set of holes (welded up) were the original 2 1/2" spacing. The other set might have been horn mount holes.
