Gixxer77 Posted June 5, 2018 Share Posted June 5, 2018 (edited) I'm about to buy a brand new set of RS smoothbores for my 91 gsxr750 Before I do I'd like to ask for any recommendations on size/type and any peripheral products I may need to get this job done like throttle cables, intake manifold rubbers/clamps, etc etc. Can I run them straight out of the box? or would I have to tune them - replace main jets adjust needle height etc? Thanks in advance! Edited June 5, 2018 by Gixxer77 incorrect details Quote Link to comment
riversbikes Posted June 5, 2018 Share Posted June 5, 2018 You will need push-pull throttles for sure. I used an off the shelf set from Motion Pro that worked perfectly. Set the floats at 17mm (they are all out), and follow the jetting guide included the manual. It's a good baseline. Quote Link to comment
Gixxer77 Posted June 5, 2018 Author Share Posted June 5, 2018 (edited) I've been informed that Mikuni distributors must advise on dual throttle cables however it's not necessary. Also I have been informed that I will not have to re-jet them, just bolt them on and hang on! Strange that it's necessary to set float heights before use... Anyway, order placed, awaiting delivery.

Gixxer77 Posted June 5, 2018 Author Share Posted June 5, 2018 Fuck what exactly Gammaboy? not using dual cables? Did you want to contribute a little more context around your response? because that's about as useless as tits on a bull Quote Link to comment
Mole28 Posted June 5, 2018 Share Posted June 5, 2018 If you run a single cable on them you run the risk of the carbs jamming wide open, especially in the rain. Quote Link to comment
MeanBean49 Posted June 5, 2018 Share Posted June 5, 2018 Personally I would invest in some dyno to to get them setup properly. Never know a set of aftermarket carbs work perfectly straight out of the box. Ive always run a single throttle cable with no problems at all. Quote Link to comment

Gammaboy Posted June 5, 2018 Share Posted June 5, 2018 Fuck running a single cable and running the risk of the carbs hanging open on the way into a corner. I'm sure some people do it, but it's not something I'd risk. 1 Quote Link to comment

I'm with you on that - Probably fine when knew ... but more likely as carbs get older - especially with Mikuni as they do not have slide bearings. besides an universal cable and push pull throttle kit isn't that expensive in the grand scheme of things. 1 Quote Link to comment
