HiI am having a hard time keeping the oil pump chain on the sprocket (all New parts). Your mod looks like a perfect fix!
I hope you don't mind, I have 2 questions:
Did you happen to make a template of the bracket you made?
I don't see in the photos where you used the torsion spring you mention.
Did you just adjust and tighten the guide in a fixed position without using the spring?
Thanks in advance!
