After my bad news on the dyno with the rings and glazed bored the engine was put back together with new parts and modifications like rings, a deglaze, 4 bar reg, piper cams and a ported 0.82 a/r exhaust housing.
last week i managed to get it running but when i revved it it went pop and stopped, I did a compression test and all were well down? Timing looked spot on on the cam pulley and etc? ok off with the head again as i thought i bent some valves but no everything mint? I take the Cat cams pulley off to find this
Bloody keyway has snapped and the pulley moved on the cams
To say i'm lucky not to of bent any valves is a miracle
New Piper cams pulley on its way
Also been offered some ID 1000cc injectors that i'm very tempted to get at a good price but hey will see how she goes with this rebuild first
