Please help.
Cheers

What makes you think a PE400 flywheel wont work on the 250?
78/79 250 flywheels are the same as each other but they are different to 80-82 PE250. Smaller overall diamter and the base timing is 90 degrees different.
78/79 can be made to work on the 80-82 but you need the matching 78/79 stator which requires a small drilling and filing job to correct the timing.
79 flywheel cant be used with 80-82 250 stator.
If you want to sell the 400 one you have, Lukeb1961 is desperate for one

I tryed the 400 stator and is bigger in the taper it seems I will need a 80/81 model fly wheel or a complete stator and fly wheel from a earlier model.

I hope someone has one for me to purchase.
Thanks for your help

theres plenty on ebay US if you dont need the charging coil for battery and blinkers.

Hmmm ive never noticed that the taper between 250 and 400 is different. i will have to check mine. No one has ever mentioned that before.

Because no-one has asked this question before     I can confirm a PE 250 and 400     1980-1981
share the same taper

Ok so looks like fatboyracing has been sold something thats not a PE flywheel. Possibly been sold a TS flywheel which im pretty sure have different tapers to PE's because i looked at fitting a TS flywheel to mine.

Thanks for your comments guys, I brought the one marked PE 400 from the wreakers and it looks the same but the taper seems to be different, I wonder if it was from a earlier model? Mind you most of the suzuki fly wheels looked the same I had an ER 185 in my hand first it looked the same side by side. I think I need to go back to the drawing board and go to the wreakers again.

It would be nice if someone had one straight off a motor maybe even with the stator. The rivots came out of mine on the weekend and made a mess of the fly wheel and the fly wheel cover.

PE 400 =    119 OD       
                 94 ID
                 1 kilo  around
                 40mm  taper to rivet base

While searching for a flywheel for my KDX the Auto elecs told me to watch for the "FP" number.
It's an ID No for flywheels. I came across a few flywheels with different No's that looked very much the same but they differed in small details such as taper size.
Ended up buying a complete motor to get the flywheel as the few wreckers I found that had one wouldn't seperate them from the motors.

There is very few other tapers on cranks, a 1:5 or 12deg included angle is almost universal across manufacturers era etc etc. The actual size may differ but not the taper. Machining an insert is perfectly acceptable  be it straight on the OD (to fit a machined flywheel) or taper to taper.

PE 400 =    119 OD       
                 94 ID
                 1 kilo  around
                 40mm  taper to rivet base     

the 175 flywheel is 1100 grams. So what does the larger 400 wheel actually weigh?

1100gm  (using the wife's kitchen scales!)
 107mm OD
 98mm ID     ( or  85mm  ID from inside of the magnets, which are 5.75mm thick )
39mm wide  ( the grey bit )
49mm wide  ( if I measure from the shaft stub to the thick area at the centre of the outside)
