GSteve550 Posted August 19, 2020 Posted August 19, 2020 (edited) Hi guys. I’m new to the forum and am building a cafe racer from a 78 GS550. Hope someone can help. I’m looking to buy a new mechanical tacho. Does anyone know the drive ratio for the GS? From some googling I’ve not found an answer, but I think it’s likely to be 1:4, 1:5, or 1:7. I would have turned the engine over and counted the revolutions of the drive cable - but the engine is in bits right now ! Edited August 19, 2020 by GSteve550 Dumb spelling mistake!! Quote
banoffee Posted August 19, 2020 Posted August 19, 2020 Welcome. I find 2 tacos to 1 beer to be a good ratio 2 Quote
GSteve550 Posted August 19, 2020 Author Posted August 19, 2020 Cheers! I reckon I’d flip that ratio 1 Quote
GSteve550 Posted August 20, 2020 Author Posted August 20, 2020 Thanks Toni. I’ve not done this kind of build before, but hopefully I should be ok - after all, building a bike is very much like......... Quote
