I'm looking to get an R1 engine in the next couple of weeks so I can start working on the wiring harness and other mods while waiting for a kit.

I have one main question thats bugging me.
I prefer to have an FI 02/03 engine (more power) but it's been suggested that it won't work unless the original clocks are used because of the ECU diagnostic routine.

I know that Mac1 have been using them with DigiDash and have had no problems. But..... I want to use traditional style clocks (Smiths Telemetrix). Has anybody used traditional clocks with an FI R1 engine and does it work? If so, did you have to do anything fancy or can you deal with it the same way as a DD? Does the DD show the diagnostic? If it doesn't then could I reasonably assume that the same bypass used there could be used for my clocks?

Ahhh, questions questions and I haven't even started yet.

I have some other queries but thats for the running gear forum. I need to get everything clear in my mind before I start spending cash.

Whoever suggested the injected R1 won't work without the R1 clocks is talking out of their rear end

Lack of R1 clocks has no impact on the ECU or the performance of the engine. In fact its slightly more complicated if you want to use the R1 clocks as you have to find ways to defeat the error codes the ecu gives out in a non-standard installation.

You can happily use what clocks you want, assuming they can pick up the required input signal from somewhere on the loom or the engine itself (via supplied sensors). This is exactly what DD does and there are many traditional looking electronic that will do the same. The DD does not look at any diagnostics that the ECU might be spitting out.

Hope that puts your mind to rest. Go for it and start spending those hard earned pennies!

02/03 R1 = 150 BHP
00/01 R1 = 147.5 BHP
98/99 R1 = 140 BHP

Is the 2.5 extra horsepower really worth going for over a 2000 or 2001 carbed R1?

Thats the sort of answer I was hoping for.
It was touched on in another thread a while back and although the DD2 is a fantastic piece of kit I just prefer the analogue type of gauges (even though most use an electric pickup).

It's a decent size chunk of budget for instruments so I just didn't fancy paying out only to have to sell them on again because of problems.

the power on the r1 isnt even hardly noticeable apart from the way its delivered and newer engines rev more

its down to personal choice carb will start easier for wiring etc

The power output output figures above are those quoted by Haynes I believe and are derived from MCN test data.

Mr Yamaha himself claimed ~150hp for all carb'd models and 152hp for the injected model. While this does not seem much, the actual smoothness of the midband was much improved improving the real performance figures quite considerably.

Talking from personal experience, there is definitely a "rough" band at around 5-6k on the carb'd R1 which is right around the cruising zone if you are running on the road.

The major benfit of injection IMHO is the ability to play around with the fuelling, especially when you upgrade things such as exhausts and airbox's etc. This is a DIY function once you buy something like a power commander.

Whoops. Didn't plan on starting a horsepower argument
