Hi Dave,

Same same really but just to add that the idle problems are really associated with the effects of the lighter weight fly wheel fitted to the 748R and also the lower weight of the reciprical parts. I compared some of these in the factory with the 9** parts and the difference in size and mass is easy to see.

This causes a loss to the normal levels of inertia and stored energy carried by the rotating mass at low revs and is not something that can easily be overcome.

As said already, the engine has evolved for the track and that is the price we have to pay..

Tough life eh?

Hmmm, this actually sems to make sense.

Mine has all the same issues (from what I remember )

As an extra point, I was initially told that the reason the bike sometimes cuts out when sshutting off suddenly was due to the effect of the bellmouths closing and because of the shower injectors the extra fuel sitting there caused the engine to cut out when stopping suddenly ???


Seemed like a bit of a story at first, but once the chip was changed and set up it seemed a whole lot better on mine although it still does it at times.

I didn't realise the R had a lightened flywheel though?? Is this just against the 99* or against other 748 models?
