You jetting is off..

Do a search on Jetting, you'll find everything you need to know to fix the problem.

 

[twpgummi1]

i am not real sure but the bike pulls good new top end and it has stock jets in it

It's running very rich...

They tend to be rich from the factory on purpose.

 

[twpgummi1]

ok so what do i need change jets if so bigger main bigger pilot or different needle clip setting

 

[Woody88]

smaller main smaller pilot and maybe higher needle clip position

 

[twpgummi1]

thanks i will try that

the position on the needle is effective from idle to half throttle. the main jet is effective from half throttle to full throttle.

 

[twpgummi1]

well i have noticed that it pulls good in the bottom and mid range but the hi rev is sluggush and don't clear out like it should what does that sound like to you

 

[Woody88]

main jet go smaller maybe 2 steps smaller and see how that feels.

I'd STRONGLY suggest you do a search on jetting, as was suggested, and educate yourself a bit before you start swapping brass.

The last thing you want to do is lean it out too far and have it seize on you.

Learn what jets cover what areas of throttle range and then figure out where you're bike is running poorly. Now you can start playing with brass.

Oh yeah, keep in mind that jetting is weather-dependent. So the jetting that works with today's temperature, barometric pressure, and relative humidity may not work with tomorrow's weather conditions.

Yes, there are ways to account for this stuff, but you need to walk before you can run.
