Hi i have a new float coming  as the old one had too many pinholes in it to repair (from ancient fuel in the bowl) and i want to be able to set the correct height.
I have the float height wrote down  but i am not sure the procedure of  measuring it?   I read about hooking up a hose to the nipple and holding it by the carb to see the float level  but i assume that would  take more steps as i would have to drain fuel, take bowl off to adjust , repeat.

This is how it is measured.

The regular settings are based on the original configuration of the bike also. Probably not an issue on yours, but if youve changed the attitude of the bike by raising or lowering suspension it will be a little different.

Where would one get a doo hicky like the one in your picture Dave?

Thought it was a caliper end! Should have gone with my first thought.

Vernier calipers are cheap, accurate & the needle never comes loose on the dial..


Takes a bit to learn to read them.,. Ive learned a few times,, I keep forgetting,, and I have a dial caliper, The HF digital ones work, but need a battery. That means always having a spare in the fridge, or risk needing a caliper & not having one,

One really cool thing abut the digital is it has a Metric/Standard button.. Talk about instant conversions..

Well.....there really isn't very much adjustment range....the amount that you can bend the little tab is limited.

Go ahead and compare the new and old float tabs....and it they appear close go ahead and put the new one on.  If you put a clear piece of tube on the drain and open the screw....you can check the level of the fuel.  When I set my float to the correct height....this is what the fuel level looked like.

I installed the new float with the carb still on the bike (pushed up on the float so it would be like it was upside down). i used a tape measure and got the measurement as close as I could and then I tested it with the hose like in your picture and i would say the level in the hose is about 1-2 mm lower than yours. I then took the bike for a test drive and it seemed to work fine then i left the bike for a few days with the petcock on (raptor) to see if anything was going to leak and never noticed any leaks but she started  hard and smelled like it was flooded (choke didnt help) i had to open the throttle to get it started but then ran normally when i took it for a drive Should I  remove the carb and do a proper measurement with a caliper if it continues to start hard or am i just over analyzing things?
  If my fuel level is lower in the tube than yours that means fuel is turning off sooner which shouldn't cause the bike to flood fuel into the head and/or air box so i shouldn't have to worry about fuel leaking in the head i would have to worry about being fuel starved from not enough fuel right?
