--I was under the impression that the 2017 and early build 2016's had a 43 degree helix...but it

seems it may be 48 degree helix...in which case do I need to send it back?

48 Deg Helix on the 17 Mnt Cat


--Thanx--

At 9000 - 11000 ft altitude , general consesus is 43 deg angle helix works best....with a stiffer secondary spring and a stiffer primary spring...and gearing with 7 tooth or just straight up 8 tooth drivers
