sound clip "stage 4"

---------------------------------------------------------
As mentioned in other threads last day or so a recording of my
"stage 4" on the dyno in march last year.
When he was taking about it dyno man said that early on the raw
fuel was spitting out the exhaust at times.
I had been riding it for quite a while like this and riders told
me it was very fumey to ride behind.
The head job that Patrick racing do is pretty good. Make sure
you dissemble it to clean though when you get it.
2mm bigger valves, high lift and porting that enlarges the inlet
port a lot.
So the 43mm inlet manifold and throttle bodies used on
Stratoliners and others do the job. They are identical to
standard, just scaled up. Its easy to grind a bit of material
away to fit them up.
The head job is what doesnt get touched in the ordinary stage 3
system. The difference this work makes is dramatic and finishing
it off by improving the inlet (which just couldnt manage first
time round) is perfect. I,m sure you could go bigger with lots
of new hardware. The cam Patrick use is not much different to
the stage 3 yam one but think lift is greater.
So before the extra inlet work was done it had about 115hp at
the wheel. After, it has 120. It feels a lot sharper. It also
runs approx 75mm velocity stacks which is about what the stage 3
ones are. Mine are silcone hose inside large pods. They dont
have flared or even rounded edges but I think still work. I like
to think that being inside a large pod gives them a "still air
situation" like an airbox does.
The dyno man said the rear wheel was spinning up a little bit.
Link to the sound file i took with the phone in the shed.

Gidday mate, ok, I took pics when doing but of course cant find
them now. So lifted tank and took a few more. Good to have a
check anyway and one clamp was loose.
So, a general pic to start.

Used DNA filters as only ones with a more solid base. Have tried
K&N as well as unifilter but these seem better. Seems to copy
K&N filter material which I like.

Arrows showing where material removed from body as well as under
the cover to fit 43mm.

43 bodies before rubber flange removed but showing grinding for
clearance as per above pic.

showing inside of filter. 43mm bodies have 50mm flange which
takes the silicone hose you can buy any auto shop.
DNA filters chosen with 60mm mount which fits the silicone hose
well.
