Just fitted my DNA STAGE 2 air intake and the restrictor due to no fuel mods (yet).
Hence STAGE 1.5
Sounds much better and while it's only a small increase in power it IS noticable.
Unfortunately the exhaust popping has almost completly disappeared so l'm going back to stock for that antisocial over run.
























Just kidding...
Next stop............Kev fuel mod.


Now to go fix my rear brake master cylinder again but thats a story for another time.
Tommorrows 300km ride should give me a good idea of how the new breather hole performs.
CYA.

before yer ride anywhere dusty....

I did exactly the same as you, but I find it's running too lean.

Taken the DNA filter and gasket out for now until I order my KevMod & O2 mod.

How one knows if it's running too lean?

Somebody told me on here!
But I guessed something was wrong...

Bottom range was crazy fast... On the back wheel in first and second!
Top range wasn't as fast as usual.
MPG dropped considerably.

Not good.
