section swept Posted March 29, 2018 Report Share Posted March 29, 2018 Your 350 AJS will most likely still have road ratios in the gearbox. Is this a rigid rear or swinging arm model, it was around this time 1954 that frames changed. You also need to check the rear hub as some had the sprocket as part of the hub. The engine may have a 14 tooth sprocket. The rear sprocket could be 48 tooth+ there are some variables and you might want 52 tooth. Is this a 16 MS ?

Mick Quick Posted March 30, 2018 Author Report Share Posted March 30, 2018 Hi Thanks for your reply, yes its a swinging arm model .the smallest gear box sprocket available 16 teeth .I think 52 teeth will lower the gearing enough hopefully thanks mick Quote Link to comment Share on other sites More sharing options...
