Which engines+year models fit in an xb9r-03 frame and what is interchangeable when it comes to cylinder heads and cylinders, like is it possible to use the heads from an xb12 on a 9 and so on...

...almost forgot, with the "active muffler control" on the 04´s how does that work with other mufflers like when you put a new system on?

Barrels and pistons are different between 9 and 12 (height differences), but heads are the same.



AMC was only on the 12s. With other mufflers, you follow the How To section...

Can the amc be cut out through ecm-spy when putting another system on or how does that work....I´m going to have a look at an 04 xb12 engine tomorrow and I don´t know what shape the rest of the bike is in

Ignition coils are the same, but you will need the throttle body from the 12 as it is bigger. The inlet manifold itself (the bit that looks like a pair of pants ) is the same for 9 and 12.

I would buy the engine, headers with everything up to and including the throttle body.

Do you know what kind of ECM you have (top right of the ECM spy window will tell you), CB060 / GB231 / IB310?

Depending on what type of belt you have, you may need the rear sprocket and belt off the 12...

Yes, you can do that...

Is the ECM cheap? If so, I would get it. We can put 12 maps on the CB060, but I am wondering what else may have changed. I'll check the "accelerator pump" settings.

Have you noticed that this thread is a party for two (just me and you)?

Can I join in then? I know f*ck all but I can hold a can of Special Brew and nod supportively now and again
