Ok this started yesterday, basicly what is happening is when i go to take off in first gear it will some times stall and other times i can get her rollin and go where i want. She idles fine revs fine and rides fine i just lose power trying to take off standing still. Right now im running 93 octane in her, also throttle response isn't that great but its fine, any ideas?

So, in goes the clutch, and you punch down on the shifter and she stalls?
Other than that, shifting is fine? If yes, clutch cable out of adjustment or clutch worn out and has gotten very grabby or contams. in the oil.

Now when you say "lose power" do you mean stalling and engine no loner running or do you mean when you start to move an apply throttle she is falling on her face having a hard time taking gas?

Gasoline is a non issue unless it's diesel. In cooler weather run the less expensive fuel unless you start to hear some pinging.

When i start to move an apply throttle she falls on her face and has a hard time taking gas. I also changed the clutch lever that could be it right the adjustment could be off.

I have a clymer manual and am going to adjust the clutch cable to those specs.

I don't think the "falling on it face" is coming from a clutch adjustment issue. Have you checked throttle response? Get the engine warm and at idle, then blip the throttle hard and see how the engine responds. See if it hesitates or dies from that. If it responds well, let it idle for a minute or 2 and try again.

These issues started once you had changed the clutch lever?

yep just adjusted it and now it doesn't die as mutch but still hesitates a bit.

sound's like the dreaded "confusing of terminology syndrome" here. Is it hesitating because you let the clutch out with not enough rpms, or does it fall on its face after you have taken your hand off the lever and it is fully engaged and pulling? What does it do if you are riding along and crack the throttle fully open? If it tries to die down and then stutter and start pulling, try it with the choke just slightly on, if it improves then you are starving for fuel, if it makes no difference then you are running too rich.

It's a common mistake to think higher octane gas helps in any way . It does not. All it does is allow you to run higher compression by SLOWING down the burn process , preventing detonation . THAT'S all it does. You actually get better performance by running the lowest octane that doesn't ping in your engine.
