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!!
