I have read here (viewtopic.php?f=53&t=14401&p=98895&hili ... rbs#p98895), that one can fit the carbs from a Bandit onto a GK73A. Does this apply to after-market carbs for the bandit as well?

Keihin has got some FCR carbs for bandits...

The Bandit FCR's fit.

without modification? an the same performance?

I have found out that the engine on the GK75 (Bandit) is the same as on the GK73. But I suspect the carbs aren't the same due to the fact that the airboxes differ

Bandit FCR carbs are a direct fit onto the 73a as both bikes share the same standard carb bodys. The FCR's are 99% of the time supplied with velocity stacks fitted and jetted for no air box. There's a air box conversion kit available but this adds substantially to the cost. Also Mikuni make the TMR's which are very similar, i have a set of these on my 73a SP but im not running the stock air box.

so what carbs could i buy that will bolt onto my bike and work as i cant seem to get hold of any gsxr ones,
as long as the bodies are the same i can use my internals, thanks

You can only use the gixer or bandit ones so its a case of waiting for a set to come up on ebay or take the old ones to a good ally welder and get them repaired, if you are any where near Stoke i may be able to get them welded for you.

hi mate, well i managed to get a set of gsxr ones for 40 quid delivered, so its all good but not sure of how good inside they are, going to throw them on and see what happens first lol
