Looking at the front mount, are you planning a gusset plate between the vertical and horizontal plates shown?

Yes, I am going to beef it up . It won't be strong enough as is.

I was taught to use the rear motor mount as the 'good one' even if it was 'off' and then shim the front. Try to match the tranny mount to the rear motor mount if you use this advice. I have yet to see a chassis, factory or otherwise, where all three planes were spot-on.

Thanks Gary, and thanks to everyone.

if you can use a steel shim and try to tack weld it to the frame it sucks when you forget to put it in depending how much it is shimed you could crack a case or cause oil leaks in the factory split

Thanks Curt, I won't forget the shims.

I did an online search on shimming the HD. This is a big problem with many responses on many forums.

So thanks for the heads up, and we will attempt to do a proper install before anything else.

My setup is different but it does apply for all 1990 and later Dyna model motorcycles.

Someone here may have use for this.

Thanks, works for my bikes...

Arrived last week;

Open primary , 6 speed trany, spoke wheels, Starter.

Working on the oil tank now, will be finished welding it today.

Check for leaks later. Or maybe I won't check for leaks, it will keep the chain oiled?

Poured a cup of gasoline in the tank, swirled it. I seem to have 2 small leaks , one along a bottom seam, the other on the outlet fitting.

Blow the tank with air before I try to fix the leak.

Is there a specific reason you used gas to test for leak? I think I'd do a little more than just blow it dry with air. Love that primary man.

It flows well. Through the tiniest pinhole. I was going to use laquer thinner , but didn't have any.

I made sure it was all evaporated before I repaired it .

The primary was the least expensive one out there . Made in the U.S. I really like it.

It fit my budget too.

Hans, on the motor mounts, why dont you just cut the welds on the rear one, or the front one, bolt the case in tight and re tack whichever mount you cut loose. If you tack weld it in 4 places it should stay in place when you weld it. Better than having to use shims. What type shims? Flat washers?

To do it so everything lines up, you should bolt the case to the mounts, install an inner primary cover and bolt the trans case in and attach your mounts and then tack weld all the the mounts, engine and trans, to the frame. It also is a good idea to have the rear wheel centered and install the rear belt, or chain, so you can make sure everything clears the rear frame tubes. Thats the way I'm going to do mine.

I am going to leave the motor mounts; there is only .005 clearance so washers could be used , but I will shim.

Today I cut out the rear trany mount to reposition it.As you suggest, I am going to line the rest up to make sure everything is in alignment.

I had to take a slice out of the seat post to get the 6 speed some breathing room.

Good to hear from you, Irish. Will this be your second or third, build? I remember your first very well.

Hi Hans, It's my second with building the complete frame. Craig
