Skaterdave Posted October 24, 2020 Share Posted October 24, 2020 Hi my gs750 77 runs standard sprockets 15-41 630. But is seriously under geared, I can cruise around town in 5th almost down to walking pace & still pull away and when out on the open Rd it is so painful cruising at 60mph it is screaming it's head off! So I've gone to 16t on front it helps but not changed much. Is it possible that the gearbox has gears from another model : smaller engine with different ratios? Quote Link to comment
Swiss Toni Posted October 24, 2020 Share Posted October 24, 2020 Possibly, Skaterdave! Quote Link to comment
Gixer1460 Posted October 24, 2020 Share Posted October 24, 2020 15/41 is taller gearing than say a standard GSXR1100 which came with 15/48 if my memory is correct! Anything that is less than 3/1 is considered long geared! Are you still using the stock wheels and tyre combination? Smaller dia wheels will lower overall gearing! What do you consider 'screaming its head off' revs as it may be perfectly normal? Quote Link to comment

Gixer1460 Posted October 25, 2020 Share Posted October 25, 2020 Also I believe the GS750 had a lower primary gear ratio so unless some drastic changes were made to the gearbox ratios, it's likely the engine will be pulling more rev's / mph than a more comparable bike - something to consider!
