I have owned this bike since brand new and have never had an issue with it outside of routine maintenance. Ran fine last time I rode it after replacing the fuel pump (about 2 months ago) but I cannot get it to stay running under load now. It will start on the first hit every time, chokes fine until warm, can rev it to redline while the choke is on and even after it warms up and the choke is off. As soon as I put it in gear and release the clutch it just dies, even if i am revving it while releasing the clutch. It will fire right back up and do the same thing over and over. I am at a loss unless I got a bad fuel pump? Any insight any of y'all smarter than me with these engines can provide to trouble shoot would be greatly appreciated.
