    My 1979 K100 has those same mounts you have posted on your old COE. Just curious why/if those wouldn’t work on the 900. Seems to me it would be a factory mount to start of with, unless the COE and Conventional are different.

    Different size holes in the frame. I didn't want to drill the frame

    The mounts won't work flipped over. The tabs would be angled upward

    Not sure if it helps but here's a picture of my engine. You can see how low the rear mounts are

    Engine in my W9 is angled as well, looks correct to me. I have a big cam in a 94 Glider….

    Not angled drastically but is angled low in the rear. This is my 1995 W900L with a Big Cam….

    I'm going to measure the front support I'm starting to think I might need to swap it

    Well winter don't give up it's grip in Minnesota. The mounts I have are not right. So I can not find the correct mounts to save my life. Just going weld some new ones. Question is how thick of steel do I need? I know a few have built there own.

    Been messing with this to long time to start at it again and do the mounts getting depressed can't find the parts I need but spring is giving me a boost of hope. Rates are horrible out west going to Midwest so perfect time to work on it lol

    Big cam 111 in a W900 B? I probably have some that are out of short hood A’s just never had any B’s around. I’ll look and see what I have and if I can find out which ones you need. You’re looking for the left and right side that bolt to the rear structure correct? Or are you looking for the pieces that bolt to the truck frame for the rear
     
    Adisiwaya Thanks this.

    Yupp both left and right rear engine mounts. The hole for the rear structure are 3/4" if you manage to find them I'd buy them in a heartbeat

    I blew up the cat in there and couldn't find Used one reasonable so took the big cam 3 626cpl out of a k100 I had. Well turns out it's not a simple take out and stick in lol trying to find the right angle for the engine to. Trying to get this going so I can start hauling hogs with it.
