Author: Subject: How much harder is a R1 5PW to install over 4XV 5JJ

Yes, I kept the manifold but had to get one pipe modified to clear a chassis tube. I am now running with slightly unmatched primaries (how much if any difference this makes I am yet to find out).

Going from the carbed to the injected motor I tilted the motor over slightly by raising the gearbox 25mm.

As for mounts it depends on the cradle used. My install uses the rear (on the bike) mounts just above the gearbox together with the silver upper crankcase mounts. Some installs I have seen use the black mounts in the head which I believe are different on the FI motor.

As regards to the fierceness of the carb engine I think this is just coming out of the 5/6k flat spot which I never managed to tune out with the jet kit.

My cradle was originally suplied to fit a carbed engine, and it's only the left hand mount that needed modifying

after looking at the various jigs we have today, the lower mounts are a different width and are 10mm higher on the injected over the carbed, and odf course the tops are different as mnentioned above, the 03 is a bit of a strange beast as everything is different and getting parts can be a problem due to only one year of manufacture,

best regards

Cheers Marc,

Sounds as though the 03 is out for me then, too much of a faff.

The 2002 and 2003 engines are the same so injection models can be sourced from two years of manufacture. There may have been slight variations in wiring but the engine itself will be identical.

So, in terms of getting spares it should be the same as the 4XV or 5JJ models, each produced for two years.

Personally having driven both in BECs the injection is a better setup to have, however I wouldn't switch from a carb to an injection model as an upgrade its not worth it. Its only worth considering if the engine goes bang. The injection is a bit more of a pain on the wiring side but thats about it.

Cheers

Paul

Yep, the 2002/2003 are to all extents and purposes identical.

Personally I would try to go injection if you can, not only for the stronger mid-range but for the ease of starting when cold and no worries about the carbs going out of tune etc.

Also, a minor/side issue but if you want or need a quiet can and airbox for trackdays but like hearing the engine in its full glory at other times, you can (with a Power Commander) upload different fuel maps for different setups in a matter of minutes whereas with carbs you can't really do that as you'd need to change carb jets etc.
