Some folks like the Lucas oil for this. Also, when the clutch is in, try giving it a little shot on the throttle. | | | | | Joined: Jan 2013 Posts: 31 New Guy | | New Guy Joined: Jan 2013 Posts: 31 | 2nd to 3rd gear works great. 3rd to 4th is anyways hard with more difficulty with higher revs. If I take extra time I can get to to drop in without grinding but would like to fix it if I can.
