theres hope!!
I took my dad to pick his bike up (he was getting a tune up and what not) and decided to talk to the mechanics about my issues. they actually talked to me for a while and helped a lot. I got home determined to find the problem... I didn't really find it, but I got it to start!
I took the float bowl off and pulled out the float and needle to make sure everything was good. I put it all back carefully. I had a 130 jet in and decided to put the 120 in since it was open. I also had my slip on muffler on ( just shoved on, not bolted down or anything) checked all my hoses and whatnot. I tried it.. it didn't work but it almost did. so I couldn't give up. with a couple tries and a little love from the throttle I got her to start up!
im not sure what was wrong but something about the mixture of everything worked!
