The exterior parts of the 550FOUR-II was diverted to upgrade the style. It adopted a megaphone type 4-pipe exhaust, same as the 750K7 one, and had a more sophisticated suspension.
Hyper pro's SPG was put in, but since Pad Valve has not been overwhelming, I added PAD Valve. In the processing of Seat pipe, hole of NORMAL is further processed to φ10, shifted by 90-degrees, and two φ8s are added on 10 mm Meter (The lower side has Oil lock peace and it could not be processed) Chamfer on Leutor and finish, Oil seal, Bush as new and reassemble.
PAD Valve is φ33. 5 tightened 2 turns, oil level 170 millimeter, Spring's Pre-road 1. 5 mm Meter (Equipped with a 70 kg ride Sag of 1 G ride does not protrude and it is the same as NORMAL) As Oil is a bit hard on ASH # 40 Oil seems to be a bit more soft, the oil level will be lower when increasing the tightening, the oil level looks better if the tightening is decreased.
Spring collar has 15 mm MeterCut with addition of PAD Valve (Pre-roadADJ, SPGetc. Cut according to change).
The rough road surface, stability feeling of sinking during Brake, etc. got better, I'm still lacking boil down, but I will set it to mind while enjoying the change.
the back whose processing of the Compression hole of a Piston rod was troublesome is unclear, although adjustment of a Pre-road takes with two rotations and is in an opinion -- it is intelligible, if it comes out, and it is peevish and I have you write by die length.The
effect did not change, so that it considered.It is completely better than there is nothing.
