r1 hitting limiter at 9000rpm!
Decided to test the rev limit in neutral (as I can't drive it due to unfinished clutch cable). Reved it and it bounces on the limiter at 9000
(according to my tacho). I have an Elliot tacho designed for 4 cylinder engines that has a scale upto 16000. It takes a link off one of my coils so I
need to see if attaching it to the other coil makes a difference (can't see it will though).
Any ideas?
Cheers,
Oli

Probably the tacho. R1 cdi's are usually pretty good.....
Spin 'er off Well...

If the tacho is correct then it sounds like a mismatched CDi from a different bike maybe.

.....unless the ECU limits it to 9k in neutral? The 2002/3 engine has a neutral feed into the multiple startup relay thing but I cant remember off
hand if it feeds into the ECU from there or not. Id put money on a miscalibrated tacho though.

Surely if there are 2 coils and you're only taking a trigger off one, it'll read half the actual RPM as its only seeing half the actual
sparks?

Most tacho's are configurable or designed to take a feed off one coil so that shouldnt be an issue

I've heard other people saying that it maybe a saftey thing that the ecu limits it in neutral to save you blowing the engine up when its cold so
maybe that's it. I won't be able to work on the car for a week or so now anyway coz I'm in leicestershire and it's in
shropshire!
