Hi all, I have a 1984 GSX 250 S (see my garage for photos of this awesome beast :wink: ). I've recently found a page claiming it's a "sleeved" down GSX 400: www dot rideastride dot com slash suzuki-gsx250.html (not five posts yet...) Does anyone know whether this is, in fact, the case? (They certainly share a shop manual). Now the bike, although mostly in very good shape (the tacho still has traces of the run-in rev limit sticker on it!), is woefully underpowered, struggles to make 100 on the M4, and in almost every way is outperformed by my girlfriend's 125cc one cylinder Bug Agility Does the fact that it's sleeved mean that there is an easy path to a 400c bike, if the sleeves are removed, and GSX400 pistons inserted? Or is "sleeving" a less reversible process than it sounds? And if I did get this done, should I expect to have to change other things on the bike - carbs? pipes? as a result of the increased engine capacity/power?
