    My bike has been sitting for a year with a full tank... I might go to pick her up in a month or so... should I change the gas?

    I don´t think I will, it´s too expensive to just throw it away!!!!

    Simple stuff first. Read your plugs 1st. SECOND... Pull jets and check them. Id start with main jet. My .02 cents

    Does your gas over there have ethanol in it? and did you add any stabilizer to the gas?

    Ya. I've been to 2 shops. First one deals with big dogs constantly. They both rejetted it and still had a huge dead spot 2750-3500. I just got done messing with it. And I think I fixed it by messing with the pump and idle mixture. Front cylinder looked slightly rich and back was a lil lean. I only rode it up and down the street but seems faster and running clean. I'm gonna take it around town and see how the plugs look after. I hope I have it fixed. I can be pussed at the shops but I'm happy I don't have to buy another. But we will see.
    **update**
    One thing I did not mention before is that both shops said and I had noticed a lot of deceleration backfire.
    Took the bike for a ride still spitting and sputtering it backfired through the carb a couple of times noticed on the bottom of the tank there is a capped off vacuum line and same on the carb The one from the tank was misting out fuel I stopped by AutoZone grabbed a hose and connected the two and now it seems to be running awesome. Except the idle was very low I brought the bike home and adjusted the idle speed and The issue seems to be resolved. Backfire seems to be significantly less as well
