Throttle Body Upgrade for 2000 RSVR

Joined Dec 2009

Hi, I ride a 2000 year RSVR with standard throttle bodies (50mm or thereabouts) and have been considering upgrading to 57mm from a 2004 on model bike. I'd fit corresponding inlet stacks but my question is: what do I need to do about the stuff below the throttle bodies? Surely the inlet manifolds would need replacing too, but then what about the cylinder head inlets to the valves? Won't they also need machining? If so this seems like a lot of work. If not I'm not sure how the bigger bodies benefit if the air flow is restricted lower down the system. Any help greatfully accepted. Cheers.
 
You wont get any benefit from them.
You dont need to change anything below the TB's.
You could get your standard ones bored to 54mm
WHERES THE Dr?

hey Scott, as TLR says - you don't need to change the inlet stacks as the throttle body houseing is the same size it's the inlet tract that is larger. You will need to do a bit of blanking off of the IACV tubes if using the later (04 on) as the earlier bikes don't use them, another thing that needs doing is male to female connectors for the injector loom.

Now having said that again I agree with TLR, the small valve heads (99-00) don't really benifit from the 57's - apparently they can be really hard to setup, the general concensus is that the 54/55mm TB's are the way to go.

I fitted 57 tbs to my 2000 and It made alot of difference alot more low/midrange
What you need
57 tb
Dr Rossi chip
Blank three holes in tbs
Short stacks of the tuono
Converter leads for injectors
And swop the fast idle off the stock tbs to the 57 tb
Then have co2 set up
You could also get a hooked air box
You may not get as much power gain as a larger head model but it's the cheapest route for power unless you have a grand for big bore kit to gain about 10-15 bhp
 
yep..had Griff fit and set up 57's on my 2000 mille ...all good

dont think just bolting them on you will get mega difference..they need setting up properly ..then every other modification you make helps..i.e. chip, filter , modded collector etc
 
were they hard to setup mark/jb? I remember reading all moggi's trials and tribulations trying to get them to work properly, as well as a the guys on af1 concuring that the 54's were better for the small valve heads. From this thread seems like they do work well.

Not hard at all mate got mine from a 06 bike turned up swopped the bits over set carb screws and fired up second try ran abit ruff Rode it to griff set co2 and went for a quick run and laughed my head off well worth it
 
Not really it dropped more when I fitted the hooked open filter cause I kept slowing down just to give more beans to hear the induction noise lol
 
I thought I had spent enough on the bike but I'm now considering this again!
I'm sure that when i researched it last time the general consensus what that there was a slight gain and a noticeable decrease in mpg. Maybe as Deacs noted earlier that Griff setting the bike up is the difference.

So if I remember correctly the 'Hooked' base plate needs to be changed or can it just be modified?
Any other changes to fit with a standard 'Hooked' air filter kit?
 
Keep the base plate if You have one all I did was dremel the holes out abit for the stacks then I took about 4-5 mm off the bottom of the stacks or if you need to buy one hooked does them for the 57 mm as the base is abit thicker so no need to mod stacks then contact dr Rossi and get a chip set up for them piece of cake to do and I felt a real gain
Cost about 350 quid depending on what you tbs for I picked mine up for 75quid I passed on a set to start with for 50 quid which I let moggi buy then I thought nuts to it a did the mod anyway if you carnt get a hooked one contact tash on here and he does the sebimoto ones at a good price and a dr Rossi chip is around 65 quid
Think in all I did it for £280
 
Hear alot of stuff about the Hooked /EVO /Renegade type filter systems but haven't seen a Dyno of a standard vs that type , I have run with excellent results over the last 4ys of me devolping my 03R the standard airbox with a 99 bottom intake & K/N filter & Single system with my own header & collector mods I did & Arrow Twinshot gun cans , this with my other stuff got 132.6RWHP on a privately owned Dyno here which is more than most I have seen running Twin systems on their bikes albe it they have only had only a blended single fuel table Dyno map done which from my testing are good but not perfect , My bike made 126.8RWHP with a single fuel map so near 7RWHP less . If anyone has a stock vs Open plate type filter system lets know as I have been designing my own system with ramair effect for top end & are keen to see some comparison
 
Sensei,

By blended fuel table do you mean an optimum fuel map for each cylinder programmed into your dynojet rather than a single map to cover both cylinders?

132.6 Rbhp, that's very good. Is the dyno optimistic? :biggrin
 
Wow, I wasn't expecting quite so much info, thanks guys. I'm now hooked on the idea. My only questions now are, who is Griff and where in the country is he located? He seems to have the know how I'll be needing.

No Apemunky .. blended is both cylinders tuned together , my first map is that & the other is the seperate map for front & one for the rear . Most Twin system Edwards etc I see Dyno tuned on here etc put out around 128 to 130RWHP & as a rule a good single system will puts out more top end If you have spent time testing on a dyno you will know that , I haven't seen on here any that have a adjustable fuel pressure regulator in their bikes either which is another means of perfecting your state of tune . . " Is the dyno optimistic " I don't believe so have used it before with my GSXR1100R Drag bike & the 2 other Dyno's I have used gave the same power output as it , only use the Dyno base figures as a guide that we are improving the state of tune & to save road testing time

Griff dyno tested a standard airbox vs hooked kit and got 6 bhp if you check ot the forsale threads i hope the dyno info is still in the advert
