Thanks for all the info. Ive been doing a lot of reading in my spare time.
I did find out what those numbers meant on the jets. I did some reading, and seems like a lot of guys running my set up and my altitude (1500'), run 280 jets. A lot of the post i read on here guys were leaving the stock pilot jets. I ordered some 280 main jets so compensate for the exhaust and air filter. I will order some 27.5 pilot jets if you think I should.
I ordered myself a Clymer manual so I can learn a few things.
Today I took the slides out of the carbs and I found that the left side slide was stuck what seems like a little in the open position. I pulled it out, and cleaned the slide and re-inserted it the correct way and put everything back together. Now, it seems to rev up normal. I still have to hold my thumb on the throttle to keep it idling, if i let off it dies.
Now, Im a little worried. I drove it around for about 3 mins while checking the how the throttle acted after I got the slide is working order, and I notice that there is coolant coming from a small tube on the right side of the bike, located behind the radiator. It looks like a drain tube, and seems to be coming from the coolant bottle in the back. Could I have possibly blown a head gasket from running the bike about 3 mins (at low speeds) with a stuck slide, or is there something else I can look for ?
