Runs in Neutral, Dies in 1st

The bike starts fine in 1st gear and Neutral. I can use the throttle to up the RPMs when in Neutral or with clutch pulled in (I've tested up to 6k RPM). After I shift to 1st and release the clutch to the friction zone, the bike dies almost immediately (within 3 feet).

The 5 min prior to this issue, the bike was very sluggish when throttling. It had sat outside for two days after working fine for about 100 miles.

It's not the kickstand. I've drained the bowls to ensure it's not water. New plugs, new oil. My thought is that it is dirty carbs.. but it works fine in neutral - and that doesn't make sense to me.

My next action would be to add Seafoam to the gas and run the gas through in neutral.

To go from a perfect running bike parked for 2 days and now not running so well doesn't really follow the usual path to clogged carbs. That usually takes a good bit more time to develop.

Maybe you have an altitude change, or vapor lock issue, or dose of poor fuel. Try running the bike with the fuel cap open. See if this will allow the bike to run better. I'm not saying to take a ride with the cap open... Try some fresh fuel.. You can also adjust the idle knob..

Come and play.. Come and play...
Forget about the movement...!
