Dezza Posted February 24 Share Posted February 24 I would guess at GS250, GSX250, GSX400 (twin, not the four as that had a rear disc) and so on. If you find the part number required then you can cross reference to other models to widen your search. I have to ask though: why are you restoring a GS425? Do you have a nostalgic attachment to this model? And welcome to OSS . Quote Link to comment

The GS425 is the same but with 2mm bigger bore. The GS850 has 69mm bore. But yeah, it's a classic GS engine, lots of parts in common. 1 Quote Link to comment
gs7_11 Posted February 24 Share Posted February 24 Oh, and just looked on CMS..... the GS450 rear brake plate is the same and there are several on Eblag. Quote Link to comment
johnr Posted February 26 Share Posted February 26 I wonder if the brake plate from the spoked wheel two stroke models are compatible, there were a lot of gt's in breakers! Quote Link to comment
gs7_11 Posted February 26 Share Posted February 26 Not according to the compatibility checker on CMS. Quote Link to comment
