Gs550217 Posted November 7, 2022 Posted November 7, 2022 Is anybody able to help with the history of my bike. This was raced in the forgotton era approx 12yrs ago. I bought this as a project it is a GS550 that has 650cc heads fitted that have been ported and flowed to 673cc. It has Keihin CR racing carbs and various other mods fitted but I know nothing about the history I have been told it was possibly ridden by a Welsh rider and then made its way to a village near Cadwell Park. Is anybody able to shed any light on the history this would be amazing. Thanks in advance. Quote

Rijko Posted November 9, 2022 Posted November 9, 2022 Quote Description GS550 race bike. Gs550 roller big end bottom half engine Gs650 (673cc) top end ported and flowed Kehnin Cr Smoothbore Racing Carbs 29mm (worth over £1000 on Eblag). Frame is Strengthened for racing Oil cooler fitted. Micron fork brace Fork seals changed along with the oil. Koni racing rear shocks Domino quick action throttle. Raced in the Early Stock Series. Bike has had new oil and filter 10w 40 semi synthetic New ngk spark plugs New brake pads all round and calipers rebuilt. New rear master cylinder fitted as old was shocking. New clutch springs. New Detent spring. Exhaust wrapped. Spare Engine is the original gs550 engine that matches the V5c plus a few boxes of spares. Sticky Avon racing tyres fitted. Bike was used at Snetterton in May, Mallory in July and Cadwell August 2022. This is a quick bike for its age. There is no starter motor so needs either a very strong pit crew or a set of starter rollers. Could help with delivery if local or for diesel money. Please no time wasters or tyre kickers. Please don't just ask if it's still available as I will not respond sorry. More pics available. May consider a swap If collecting is from Sandy Bedfordshire. either way, £1,750 sounds like a pretty good price considering the way the bike is setup. 1 Quote
wraith Posted November 9, 2022 Posted November 9, 2022 Welcome to OSS, Can't help with your question, but a interesting bike. Had some years ago a gs550 with a gs650 top end, definitely gave it a bit more up and go over the standard 550. If the OSS racers section is open to you? Try asking in the race section Quote
