Adjustments to float height
« on: May 06, 2009, 07:26:41 PM »
Hi,
I've been trying to find info using the search button but no luck.  ???
Can anyone tell me what height the floats should be on my F1 and how you go about doing it?

Many thanks
Andy

CARBURETOR ADJUSTMENTS
Float Adjustment
The carburetor assembly has to be removed
and partially disassembled for this adjustment.
1. Remove the carburetor assembly
2. Remove the screws  securing
the float bowls to the main bodies and remove
them. In order to use a float level gauge it is
necessary to remove all float bowls for gauge
clearance.
3. Measure the distance from the bottom of
the float to the float bowl gasket surface
 The correct height is 0.61 in.
(15.5 mm). Use a float level gauge
4. Adjust by carefully adjusting the tang on
the float arm.
CAUTION
The floats on all 4 carburetors must be
adjusted to exactly the same height to
maintain the same fuel/air mixture to all 4
cylinders.
5. If the float level is set too high, the result
will be a rich fuel/air mixture. If it is set too
low, the mixture will be too lean.
6. Reassemble and install the carburetors by
reversing the steps.


I pulled thismout of a manual, hope it helps. Do you have a decent manual for your bike? If not have a look on the US site ( http://www.sohc4.net/index.php?title=Main_Page )

Cheers

Thanks for that Seamus, the float tool link will come in handy.
