Here's my old gsx it's a 1981 so is 36 years old also being an 81 it's an ex with the 24l tank not the 19l and is one of only 11 left.
The bike starts and runs fine although I would recommend the carbs get balanced and tuned,it has new tyre's fitted and has renthals on it but also comes with the original bars an mirrors,I have been riding the bike for almost two years with no issues.
Only selling because I've just bought a new bike.
The price is firm but I would consider a px for a classic car or Bedford cf.
