Desmoconversion of non Desmoheads

Post by hedton » Sat Mar 31, 2018 10:50 pm

Desmoconversion of Gts heads. The holes are 10mm in diameter 10mm H7= 10.00-10.018mm. And they are 89mm deep. Predrill with a center drill then a 6 or 8mm drill and then a 9.7mm drill and then use a 10mm H7 reamer. The holes are X=35mm, (both ways) Y=11mm (both ways). Zero is the camcenter with the openrockerholes in line.
