elec. cut outs

I used the DMH cutouts on a twin 2.5" system. The motors were reliable enough, but the butterfly shaft bushings got sloppy due to heat and wear.

I contacted DMH twice to see if they could supply new bushings - no reply.

I eneded up shimming them but it was a temporary measure and they have started rattling again. I doubt I'll re-fit them.

And yes, they will lean out your AF - I had to run two stages richer - but made 15HP more with them open when I did.
