Spring identification.

[yorkshireracer]

I'm converting my GS550 into a post classic racer and need new fork springs.
Trouble is, the bike is a complete bitsa with '78 engine and '79 frame and as for the forks ?
Every model seems to have different springs and the ones in mine don't match anything. Is there any way I can identify what the forks in my bike are ?

It really shouldn't matter, pretty sure all 550s from that era had 35mm forks and should take the same springs.

Post classic racer?

Is that a polite word for cafe?

How long are your springs?

The aftermarket one are longer than stock

My experience has been that std Suzuki forks are undersprung for circuit racing and the rears are oversprung...

Personally I'd go straight to an aftermarket fork spring - there still may be some fiddling with spacers and oil but it will be a lot closer to correct than OE. I see Progressive list a replacement.

Talk to Rich. I would go for a straight-rate, not progressive.
