Gear Ratios

[Guest oms]

Can anyone help me with the gar rations for a X-11 box? I'm looking for primary, secondary reduction and 1st - 5th ratios!

Many thanks in advance!

Hi oms

I've posted the ratios as an image in our x11oc sharing folder.... it's called "x11_gearing.jpg" and down near the bottom of the page.

Thanks fast_eddy.

We think we've just bought a race tuned X11 engine for our hillclimb single seater but under the impression it was a blackbird engine! Now we know it's got 5 speed box we suspect it's an X-11 engine in a high state of tune;

2mm overbore

Oversized pistons

Strengthend rods

gas flowed head

Kent Cams

Baffled sump

Balanced and lightened crank

A quick question, is there anyway I can quickly determine whether it's an X11 or Blackbird engine. The only difference I can see at the moment is the thermostat housing.

Thanks again!

The 5 speed box is the give away... x11 has a cable clutch, they have different rear engine mounts too.

errr, most x11's have gold coloured clutch and alternator covers

Just been out to the garage, looks like we have a blackbird engine with an X11 gearbox. At least that's my current best guess!

Does the bird motor have two balancer shafts?

[Guest fe5ta]

Yes it does, can`t understand why Honda chose to only put one in the X motor

They did it so you still had the vibes of a real engine
