Stanman Posted February 2, 2023 Share Posted February 2, 2023 (edited) Hi, I guess you have been asked this loads of times so forgive me for asking again. I have a 96 gsx600f I would like to run it on pod filters, years ago I asked the same question and someone just told me to change the main jet to a certain size, (???) this worked fine first time. Would anyone know the best settings for the carbs to run well on filters please? Many thanks. Edited February 2, 2023 by Stanman Quote Link to comment
TonyGee Posted February 2, 2023 Share Posted February 2, 2023 just changing the M.J. won't fix it, its more involved than that. why are you fitting pods ? Quote Link to comment
DAZ Posted February 2, 2023 Share Posted February 2, 2023 Couldn't really say what size jet you would need , dynojet offer a kit that includes jets and needles to suit pod filters not everyone is a fan of these kits and will tell you every engine needs tuning individually but every factory bike is jetted the same and I've used a kit on my old 1200 bandit an tbh it ran mighty fine 1 Quote Link to comment
Captain Chaos Posted February 3, 2023 Share Posted February 3, 2023 first question should be what bike? GSX600F or Bandit? Quote Link to comment

Agree but it's pretty much the same engine and apart from the 88/89 teapots I think many 90's models shared the same 32 BST carbs, mk2 bandits and baboons arse teapots may vary possibly BSR with tps sensors like the 1200 bandit,but dyno jet kit is available for all I believe if that's the way stanman wishes to go Edited February 3, 2023 by DAZ Bleeding predictive text Quote Link to comment
Stanman Posted February 3, 2023 Author Share Posted February 3, 2023 Bandit 600, I'm building a chop so there's no room for an airbox as such, when I built it the first time around years ago it run well on pod filters, I just can't remember the combination that I used Quote Link to comment
Stanman Posted February 3, 2023 Author Share Posted February 3, 2023 It's a mk1 1996 Quote Link to comment
spiderpig Posted February 4, 2023 Share Posted February 4, 2023 Really you'll have to get it on a dyno to get it spot on with pods. Will run better with duel pods rather than individual ones Quote Link to comment
BikeJake Posted February 5, 2023 Share Posted February 5, 2023 Pods often don't run well on CV carbs due to the way they attach to the carbs. Depending on any step at the mouth where they join the carbs. If there is no step they will be OK. I've bullt several specials with CVs not a Bandit, but they had CVs and one set of pods would have a huge flat spot that no amount of. Rejetting would ever be able to fix. Suggest. You find out what pods others are using with some success Quote Link to comment
yantosh Posted February 5, 2023 Share Posted February 5, 2023 i've used the standard airbox rubbers with twin ramair foam filters on loads of builds, fi, carbs, water cooled , oil boilers ... always worked, every time this is a 750, in a bandit 6 frame , foam filters and airbox rubbers , ran great on dyno and real world 4 Quote Link to comment

Devilman Posted February 5, 2023 Share Posted February 5, 2023 From memory Bandit 6's are very prone to rough running without the airbox, to the point where I've heard people say that jet kit(s) didn't really help at all, the only thing that fixed it was Dyno time. Quote Link to comment
yantosh Posted February 5, 2023 Share Posted February 5, 2023 i'd choose dyno over a jet it every time Quote Link to comment

DAZ Posted February 5, 2023 Share Posted February 5, 2023 (edited) Thanks @yantosh just scanned through you pics, you've built a great bike man,those yokes and fork brace are really cool pieces, and the fit and finish looks great Damn missed the engine case on first look through...

Archie Posted February 8, 2023 Share Posted February 8, 2023 Same - everything I read when trying to find new pods for the gsx / 600 thing said bandit 600s run crap on them. Was gonna go with ramair foamies, but was too tight to pay £20 odd a filter. Got some new cheapyish ones like that were on there and we’ll see. if space is an issue there were some universal real slim line ones on the net, but who knows what quality they are Quote Link to comment

The real problem is that 99% of the time when someone fits pods, they stick them straight onto the carb mouth removing / disposing of the rubber "velocity stacks" that are built into the stock airbox-to-carb rubbers. (K&N Dual Pods are very notable for this, there simply is not enough room to use the stock airbox rubbers) As shown by @yantoshabove, if you include the rubbers from the airbox (and with the right foam filters) it greatly helps with getting them to run nice Quote Link to comment

CV carbs don't work the same as slide carbs they must have smooth air at the lip Quote Link to comment

(K&N Dual Pods are very notable for this, there simply is not enough room to use the stock airbox rubbers) So how do you explain a Dual Pod equipped GSXR1100 working fine with just the addition of a DJ kit ? Yes, a DJ kit modifies the way the slide responds but doesn't require intake 'modification' of airflow. On 2/6/2023 at 7:01 PM, yantosh said: Just turn the rubbers upside down then you aren't wedging the foam against the frame ? And forgive me for noticing but the carbs in the pictures above are slide types so will virtually function quite well without any sort of induction modification IMO. 1 Quote Link to comment
Dezza Posted February 25, 2023 Share Posted February 25, 2023 That's a good idea using airbox rubbers to mount twin Ramairs instead of expensive bellmouths. I wonder which ones will fit Mikuni RSs. Quote Link to comment
bluedog59 Posted February 25, 2023 Share Posted February 25, 2023 (edited) The airbox rubbers form part of the tuned inlet tract length in much the same way as exhaust lengths, pressure pulses travel up and down the tract and reflect off the open end or the end cap on a pod filter. This can play havoc with the jetting ( LC Yamaha's suffered from this until the late Leon Moss developed a spacer to move the K+N backwards to correct it). It's worth noting that the rubbers also project into the airbox to allow air to be drawn from all round so running stock rubbers with a sock filter over them will help everything work in harmony. Yantosh's set up above is a good example. The important bit is the length to the end of the rubber is maintained and the foam end of the filter will not give a surface for a pulse to reflect off.
