What do you mean un-rideable paologray? The reason I ask is that my 750 Sport is a bit ... erm ... awkward under 3000, probably best to describe it as a bit 'over-responsive'.

kwikbitch has the same bike as I do, and she's suggested a mod she did on hers, which was a change of rear sprocket. Apparently that smoothed things out a bit.

Not sure if your problem is the same, but thought it might be worth a mention.

All of the carby twins can get lumpy below 3k.
1. Throttle synchronisation is _really_ important.
2. Std idle mixture is _way_ too lean - you need to run about 4 turns out - cos weak mixtures at idle produce uneven firing.
3. The ignition advance curve is too aggressive really anyway, and can cause poor sparking under low-rpm-load, and makes all of the above worse, but you cant do much about it, except fit expensive coils so you get a better low-rpm spark.

Work on the first two and you will get it in better shape.
The 750's are smoother than the 900's, believe me.
My wife doesnt like the way the 900's develop power low down cos she says it makes it very jerky to ride, so I tell her to ride faster
