48mm THROTTLEBODIES

[Ked0607]

So if anyone is following the re-release of the GSXR 1000 and have read all the ways they gutted the power to meet EURO5+ you must have noticed they went LARGER with the throttle bodies. How far off in mounting holes is it from the GSXR1000 to the BUSA? The setup looks very close in pictures just dont know if it could bolt up to our bikes.

Oh no. Now you're giving me something new to obsess on. 48 mm throttle bodies, porting and polishing the head, bigger cams, bigger valves, new tune. Oh brother !.

Well, I guess we need to get a Busa throttlebody and a 1000 throttlebody and see what's what.

I am assuming its wider from the photos ive compared on ebay between GEN3 and the 17-24 GSXR1000

i brought this up with the previous gsxr tb and how they are 46mm. those are already bigger than the gen 3 busa ones. they use the same mikuni plug to operate. the tb housing does separate in the middle so it might be too hard to space them to fit.

Then it can finally match the 2 in performance lol.

In terms of aesthetics, I don't think they could have gotten the Gen3 more perfect given current trends in style. I think it exceeds Ducati in the beauty department and it will endure for very many years. In terms of performance, I'm sorry, it's a great example of 'be careful for what you ask for because you just might get it.' ...at the expense of what you already had. Brings to mind a three wishes genie fable. After these years, if no one has found a clear cut hidden path engineered into the bike, it's just a calmer, gentler busa. I'll wait for a Gen4. maybe in two or three years. They couldn't let us down twice in a row.

The 1k and GEN2 / Gen3 spacing arent too far off, at least as far as the head ports go.

Gen2/3 above and 17+ 1k turbo plenum below. This is the direct head interface, not the boots for the 1k.

1k is 70-90-70
Gen2/3 is 75-90-75
Gen1 is 80-80-80

the sensors and the connectors look the same so it might not be hard for the electronics to communicate. the tb assembley is bolted together from 2 pieces. wondering if splitting the 2 halves to better space them might work. the otherchallenge would be to change the cut out for tb in the lower air box assembly. maybe swap injectors if they have different flow rates. new velocity stacks. new tune.

So a little offset and a flexible outer boot from head to TB would work.......
