can i ask y are the holes off center i new to this site .. is it so u can get your vale tappet ClaranceThe Dormier reamer worked out fine. Drilled the hole 1/64" off the centre and reamed it. Trial fit in the rocker arms and all seems OK. Most probably will do the 3mm studs for the bushes.
Hi Barry,When I have to bend a tube.......
-close 1 side
-fill it to the top with table salt & shake a bit
-close the top than
-open the tube & let the salt coming out
Than you have a beautifull bend.
