Title: Making Shifter Adjustment On 700 Twin
Post by: High On Octane on May 13, 2013, 11:05:27 pm

I need to make an adjustment to my shifter and am curious as to which direction and how much movement in the change I need.  Basically the transmission shifts into every gear fine except for into 3rd.  Under normal driving, there's absolutely no engagement into 3rd.  BUT, if I accelerate to the top of 2nd and hold the RPMs up for a bit, it will usually shift right into 3rd.  Also on occasion I miss the downshift from 3rd to 2nd.  Thanks.

It's an Albion gearbox get used to them shifting weird. They're rugged but not the best easy shifters. Hitchcocks has a rebuild and set up on their site that can help.  ERC

Basically there is no adjustment other than moving the shift lever up or down.

Yes there is on the gear selector strike plate and the tension adjuster.  ERC

Albion gearboxes didn't have much of any adjustment for common wear of components. Everything was set up to go into its proper place when new. After they get wear on the shift pivot, rachet, shifter fork, and gears/shafts/dogs, they can get to a point they don't want to go into some gears well. This led to filing the holes out in the shifter guide plate and even modifications to the plate to allow more movement but in most cases, a good overhaul with replacement of excessively worn parts will do the trick.

I tried to adjust the shifter plate, but the holes were not yet slotted and I didn't feel like tearing it apart at that time.  However, 3rd is the only gear that has trouble shifting and I have discovered how to overcome the stubborn 2nd to 3rd gear shifts.  If I keep light pressure on the shifter BEFORE I pull the clutch to change gears to 3rd, I can actually feel in the lever when it's "ready" to go into 3rd.  The shifter feels "loose" until about 3K RPMs and then feel the shifter become "solid" indicating that 3rd gear is pre-engaged and ready to shift. A little inconvenient, but nothing major.  Just another quirk to add to the bikes character.

Holding pressure on the shifter takes the slack out of all the mechanism parts. It doesn't take much play to cause a problem.
