rvf400 33hp restrictor?

[mike]

i want to take out my 33hp restrictors on my rvf400, where abouts are the restricters in the cars are they deep inside or not etc?

[mike]

thats carbs not cars!!

[craigT19]

i think there in the carbs but carbs are complicated so best bet is to get a garage to do it:)

It's pretty simply to remove the 33bhp kit from the RVF, but it's a very fiddly job...

• Remove the two side mid panels
  
• Remove the lower fairings and all the assorted rubbers / foam pads
  
• Remove the seat, and unbolt the tank
  
• Remove the two "air funnels" which lead into the tank
  
• Lift the rear of the tank up somewhat, and turn the fuel tap to off
  
• Pull off the big hose on the left (overflow)
  
• Pull off the small hose on the left (vacum connector)
  
• Pull off the small hose on the right (breather)
  
• Now you should be free to lift the tank clear
  
• Remove the airbox covers, nothing which way around the air tube to the secondary air filter is fitted
  
• Pull out the air filter and unscrew the bottom airbox bolts to free it
  
• Remove the whole dealie so that you're left with the carb bellmouths
  
• Free the idle adjuster and choke cable from the left of the bike
  
• This is the really fiddly bit: use a long crewdriver to loosen the clamps holding the carbs to the intake manifolds
  
• Remove the fuel hoses from the carbs
  
• Tug and pull to free them, they are quite stiff to pull out because of the V shape they're stuck into
  
• Now you should be left with the intake manifolds visible, remove the restrictor plates
  
• Re-assemble the whole lot
  

Et'voila! Twice the power... By far the hardest bit is getting access to the clamp screws on the intake rubbers - the rest is easy but drawn out, but good golly miss molly is it worth doing

The power is quite good, even when restricted to 33bhp you still have the torque so it's really only the top half of the rev range that isn't as psychotic as it's meant to be. 0 to 60 was around 5 seconds on my bike when it was 33bhp'd.

Speed? Well I had 120mph out of my 33bhp RVF, given a downhill stretch they'll go all the way to the top speed of 145mph.

Handling and braking is unaffected by the restriction so you can still outrun the lardy litre bikes without a problem.

Hi
Does that go for all 400's

+ So would i be able to keep up with my mates de-restricted VFR. Could i be able to pull wheelies

Course you'll be able to pull wheelies!! You can pull wheelies on an NSR!! So it ain't gonna be rocket science n an RVF or similar is it??? Just ask Zimma if his ZXR wheelies..........hehe

Well the illegal bit is 'not being in proper control'... and I allways thought wheelies showed good throttle control

[Ropehead]

i'm looking at getting a zxr400 a.s.a.p cos it not an import, but i really like the vfr and fzr but i'm put off cos its hard to get parts is this true???

Cheers

Luke,

I fink it's "M" Reg, it was on the Dobles website for a while in
it's origional black and red colours, the bike looked good but
the colour put me off! I thought the red wheels wus over the top.

They say it's a minter wiv 10,000kms on the clock, so will have
to have a good look when it's done. The good fing about buying
from a Honda main dealer is the Warantee!

Good Luck

Mole

[Scooby]

hehe Zimma I love your bike I want one now!!

What year is it??? I am guessing here at about '92???

Cheers

No actually, it gotta be newer than that. Having a closer look I would say '97ish??? God knows why I said '92...

If I remember he got it new pretty recently, they haven't changed the design much in a while.
There's not *that* much you can do to make 400s faster/lighter weight with out making significant compromises so they haven't changed/made new designs recently. (And the jap power laws were relaxed)

[mike]

thanx for the info kornel,ive got a workshop manual so i will read that before going in head first so i dont knacker something in the carbs.

[Zimma]

feckin 92 grumble groan feckin shit bollox!

nah its an ZX400L9 according to kwaks website, which means its a 99 model, altho i bought it in 2002. basically they havent changed the design of the bike since 99, so technically i coulda got a second hand 99-2002 model and had the same bike, but u no... i like debt, so i got a brand new one 8)

G, u can make em faster... 444cc
