UPDATE.
made a tool to remove the flywheel,
standard 220 stator (with 85w ricky stator lighting stator)
1990 200 SR stator
as you can see the source coil are in completely different places!
standard 220 & 200 SR flywheels (SR on the right)
rear view ( SR on the left this time) you can see the pickup point on the 220 flywheel, SR flywheel don't have this.
I was going to put my 85w stator in, but upon closer inspection you can see that the SR lighting coils are wider than stock, and wound with similar wire to the 85w stator! so I will leave these alone!
so in short the 1990 twin lighting SR stator will work in a newer 220 (mine is a 2001) BUT you will need the stator & flywheel, the flywheel fits the 220 crank perfectly. 1 thing I did notice was a lot more kick back when trying to start the bike, took for a test ride and runs great ( a bit rich, just gone down a main jet size and will take it out again.
just keeping the thread updated in case anyone wants to do something similar.
best regards
John
