does any booty know the spec for dry float height on an 88 fzr 1000?

According to Ye Officiale Yamaha Manual, the float height is 12-14mm above the gasket surface. This should give a fuel height of 10.5-11mm above the cast-in line on the float bowl.

Yea,I'm not sure where Haynes gets their specs. In the Haynes manual I have each carburetor spec sheet is preceded by a specific carcuretor type. Example : FZR 1000 (87' and 88') carb type Mikuni BDS37 (four) lists a fuel level 7.3 - 9.3 MM.
FZR 1000 (89-on) carb type Mikuni BDS38 (four) lists a fuel level of 10.5 - 11.5 MM on the 89' and 10.6 - 11.6 on 90' - on.

This is float height quoted on the "factory pro" website for the 89 - 95 EXUP, not the 87/88 Genesis

The Genuine Yamaha manual doesn't give a procedure or figure for the dry method (float height), only a fuel height measurement that is done by connecting a clear tube to the drain on the float bowl and comparing the height of the fuel to a mark on the bowl.

Yup - brain cramp on my part. The wet fuel height for the 87/88 is 7.3-9.3mm above the cast-in line.
