Why isn't there a red line on my rev counter (900SS ie)? The gauge goes up to 11k rpm, but the limit 'for normal use' is 7,500. Is it because you can tune/ balance the engine so that you can run to higher rev limits? If it is, then what would be the benefit - usually we tune for power, don't we, rather than for higher engine revs? (I always thought that the reason for the desmodronic valve arrangement was so that you don't have valve bounce at high revs - but this is nowhere near the range where you'd get valve bounce, is it?) Perhaps it's just so that you can apply a bespoke dayglo line on the dial. Just wondering... Nick
That's because the IE isn't as good or as fast as the carby versions; so Ducati want you to blow your's up.....
just checked mine I don't have a redline on my rev counter either on my ie mind you 7500 rpm is when the power on mine seems to kick in seem to remember taking the revs somewhere near 10500rpm and its still alive also seem to think I was told the "redline" was 11000 but sure someone on here will have better knowledge and say for definite what it is
now now can we just stick to red versus the slower yellow ones please any more of this and my ie will need counselling
Don't pay any attention, Carby SS owners are a grumpy lot. They can't buy petrol for their bikes since petrol stations stopped accepting shillings as legal tender.
Don't they have rev limiters? Reason why the 999 doesn't have a redline. It's meaningless, as you can't put it into the red. Surely 916 the same. There wasn't any point revving the tits off the 907ie. It wasn't that happy at the top end and didn't seem to get that much faster. Maybe all the two-valvers are like this.
OK. Gliddofgood, I think you're right. It does seem rougher when highly revved. And I suppose as the smaller engines have a higher rev limit, it saves a bit of money if you have common rev counters across the range. Talking about saving money... it seems pretty strange to me that there's a spare light position on the dash where the oil light is on the rev counter gauge rather than with the rest. You can see it on Tobytyke's picture above. I guess again for commonality/ cost reasons... ... anyone use this spare idiot light position for anything?
Don't you mean farthings, not shillings? Still, at least carby SS owners are proper mechanics................
...they have rev limiters......mine cuts in (very abruptly!) at about 8k (500rpm above peak hp?)......takes a bit of getting used t compared to 11k on my old 955i Daytona
