Hi Folks,
I posted a problem last September and, while I can ride pretty consistently I am having a nuisance problem maybe you can "float" around your brains for me.
My original post here: http://www.motoredbikes.com/showthread.php?t=15542
Bike runs great, starts right up every time, never have had to choke it.
Here is the problem: My engine is always getting too much fuel at speed and I have to constantly on/off on/off the fuel petcock to keep it running. I am sure you can imagine that on a long 10 mile run this gets very annoying.
With a full open fuel petcock it quickly loses power so I shut the fuel flow off and it immediately picks right up and runs sweet for a pretty good distance till it starves. I open the petcock for just a couple seconds till the bowl fills and then off again.
I have adjusted the carb float tangs to a lower position but then it seams like it starves for fuel. It's either too much or too little. I have taken this carb apart so many times I could do it blindfolded and can't see what the heck the problem is.
I am a mechanically inclined person and I'm just not getting this. I can park it running with the fuel open and it will idle all day. It seams like when the throttle is open at speed there is so much vacume into the cylinder that it's drawing more fuel into it than it can use and by doing that it constantly fills the fuel bowl thus supplying even more unnecessary fuel.
I have read all posts here regarding this and I am befuddled.
Any thoughts? Am I missing something?
I have not altered anything on the HT kit other than, because I mounted my engine slightly more upright than most people, I "leveled" the carb intake so that the fuel bowl would be level.
Is it supposed to be "not level" (I don't know how else to say that) and tilted downward toward the rear? That just seams like a silly thought...
Thanks.
