Title: Float adjustment question
Post by DrunkenDwarf on 04/28/13 at 22:29:36

I had a low speed lowside in December and haven't ridden much since. I've finally found time to repair the minor damage and decided to pull the carb and rejet (new jets: 52.5/150), since I knew it was running rich and I was going to have it apart anyway.

While I had a carb out, I measure the float position per Clymer's. It was 23mm. That shocked me a bit. I adjusted it up to 26mm. I know that's not in spec, but I didn't want to over adjust in case something was different with my float.

Now when I try the clear tube attached to the bowl drain test, it comes up a good 5mm below the gasket. I did not have the foresight to try this before I started bending things.

I'm not looking forward to pulling the carb again. Getting it out was a royal PITA, even with the battery box removed.

Anyway, my battery is dead (one cell was almost empty of liquid, I don't know if it spilled during the low side or something else) so can't ride until I try to charge it or buy a new one.

My questions:

When people describe the fuel level as slightly below the gasket, what does "slightly below" mean? 1mm? 5mm?
Without riding it and having it die because it's too lean, is there a third way to verify the float level?
Why do I always create more problems for myself? ::)

1mm, 5mm,.. it ain't gonna' make that much difference...
As long as it's below the top of the bowl somewhat near there... (it's changing all the time as you go bouncing along anyway)...
4mm must be like .2 of an ounce of fuel...
Don't worry about it...

I tried the clear tube method once after setting my floats - and I was below the gasket surface about the same as you. On my bike I doubt if there is enough adjustment in the flloat tang to get it up to the gasket.

So, how low is too low? Halfway? For us newbies, what are we looking for?

It definitely needs to be up near the top......the level does affect the opeation of the jets and the fuel mixture. The lower the level the less fuel that flows.....and the mixture will be leaned out.
