Light Weight Flywheel ??

Reading about light weight flywheels and the like.

Has anyone fitted one to a 748S ?

If so what difference did it make ?

I fitted a light weight clutch basket and the engine spins up much faster I am assuming a similar improvement can be expected

But I've been wrong before

If you are watching the BRNO Moto GP we are the eleven on the front row of start finish with the James Ellison T shirts spelling GO ELLISON 77

Hoping for a good weekend (60p a pint)

I'm sure Nelly had one fitted on his 748, it's something I've been considering for my 996. He'll do you a good deal on one I'm sure aswell.

I've got one fitted to my 996. I haven't noticed any loss in engine braking but what I have noticed is that it spins up a lot quicker. Put some shorter gearing on yours as well and it becomes a lot more entertaining!

Great upgrade, really makes the most of the revvy 748 motor!

The alloy flywheel is about 800g lighter than standard, so even more weight saving than the light clutch and right on the end of the crank!

feels a bit like a lower gear, but unlike lower gearing, doesnt run out of revs faster.

Word of warning: get it fitted properly, note the type of locktite to use and the torque settings. well worth re-torqueing (not sure about spelling) at each service. If it comes loose it destroys itself and takes the main bearings, and maybe the bottom end shells with it.
if you are not spanner happy, then pay an engine builder, who has done it before, to do it, it will cost about 3 hours labour, some 3bond and oil/filter. but if it comes loose you get full comeback.

a cheap and fun performance mod.

There are three types of flywheel on the 748-9**'s.

The early 350W alternator bikes, which I think Khushys flywheel will suit, have two yellow cables coming from the alternator.
The later 550W units have three wires and use a different flywheel.
The last ones are the SPS flywheels. These bikes use the P7/P8 ECU's and have two flywheel pickups on the LHS cover.

1999 is the approximate year for the change between the first two, but you can get 350W bikes registered late....

After the cans, it was the next mod I did to my 748. It was also a must have in my new engine to. Love it. Spins up quicker and improves engine braking slightly. Great mod!!

Agree with Nelly (well, how could I not). One thing the lighter flywheels will highlight is if the fueling setup is less than ideal. That is, the larger mass of the standard flywheel can mask marginal FI setup. It might be a good idea to have the FI checked and setup at the same time you fit the new flywheel.
