Rocket 3 tourer 07
Hi guys, gearbox has gone on my rocket, diagnosed with mechanic.
Going to swap engine
The engine number on mine is 3243986 on an 07.
Ive found an 05 with the number 3229981.
Are these compatible?
If it makes a difference the 07 is a black engine, the other is silver
 
Yeah straight swap.
Although the 05 will likely have a few superseded internal parts that the 07 has newer versions of.
But even the 07 has superseded parts.
 
Yeah the engines are the same fitment wise from 04 to 16/17/18 whwener the last Rocket III was registered.
They change the sump very soon in the early days but this dont affect fitment to chassis.
In 2010 onward with the Roadsters the engine management was updated so different ECU, GPS and map to suit new exhaust. Touring in 08 onward too.
But anyway as long as the exhaust goes with the chassis the engines from any year will work with any year chassis.

Just have to bear in mind that the older engines may have old superseded parts in them that can fail, newer engines have the updates.
 
One final question, the engine casing on the new engine is missing, can I use the one from mine, ie will the bolts be in the same place
 
Yeah it'll go alright. Clutch too coz that's missing from the silver engine!
The camchain guides were updated a couple times since those too but that's something to consider, not quite as necessity
