I used a 62/42.40 with stock springs and mtx weights loaded to 75 grms, and stock gearing.What did you end up for on clutching? Did you gear it back up? Good to hear that you got it running.
also ran in non eth mode.
what supprises me is, how .40 if an inch of 62 deg is long enough distance to create engine load.
One thing I did notice yesterday was, when I was sidehilling, I was more out of control and im not sure if the new clutching has anything to do with it, perhaps a backshift issue.
