With the standard flywheel, there was not much free space left in there, most of the volume was contained in the 2 halves where the rod is located, it really is a snug fit in there as standard.
Its either going to go 1-of-2 ways .... it will be either totally rubbish or will rev like a good 'un !! Time will tell !!!
Bought a clutch of eBay other day and it contains dimpled steel plates .... never seen a TY with dimpled plates before ...... its a trick often used with Mont 315R plates as these are same as CR250 'Sureflex' MX clutches. Dimples hold oil and prevent drag when faffing with gears etc stops the steel plates sticking to the friction plates.
I think your scooter bloke is talking cr-p, I think it will be gutless.
