I could use a bit of help please.

To allow the twin calliper/disc set up I bought some 1975 CB550 SS forks (the blue ones).

Having stripped both the original 1972 500 K1 and the 550 forks, there are the following differences.

500 tubes are about 7mm longer than 550.

500 internals have a continuous rod through the spring.

I need to combine the 500 (longer) tubes (as the 550 are shot) with the 550 sleeves for dual callipers.

Questions.

Are the 550 internals an upgrade?

If so will the extra 500 tube length be a problem?

Or, do I use the 500 internals with the 550 sleeves?

Any thoughts?

Only combination that worked was 500 parts in 550 outer.
All good just need to fit oil seals and refill.
Any thoughts on callipers behind the fork legs?

Long time but a quick update and hope to share the rebuild bits from here on.

Just back from powder coat.

Finally started reassembly.

Steering and engine.

Lay the engine on its side, lowered the frame over. Long bolts first. No scratches, no problem.
