Mark,

If you want another TM28SS, they were also fitted to TZR250 (all 1KT-based models and some 3XVs), TDR250, DT200R, some DT125Rs and maybe also some later TZR125s...?
Beware that other versions of the TM28SS may have different sized power jets pressed into the float bowl and all versions have some slight differences, but these shouldn't cause you any trouble. You can gain some additional adjustment by converting the TM28SS carb to TZR Formula 3 specification.

Alternatively, there is the TMX30, as fitted to the WR200 and DT230. The TMX30 is also available aftermarket (https://www.sip-scootershop.com/en/products/carburettor+mikuni+tmx+30+_40070000).

If you want a carb bigger than the TMX30, I think you'll have to change the inlet rubber. I don't know whether any significant performance improvement is available without doing other engine modifications (e.g. exhaust, porting, compression, ignition etc.), but you may be able to find some info somewhere.

Regards,
James
