I am in the process of resurrecting an 06 250 that was dropped and then left sitting for 2 years. fall was on the right side and seems to have involved significant sliding as the front master cylinder and brake lever are both ground down.

I have done the major points, oil, brake work, carb cleaning, new gas, and other small things I cant think of atm.

Currently the bike will start reliably and stay idled however the right cylinder does not seem to be firing on its own, it seems to start up if I rev to about 3-4k and it will also start if I remove the air box and block the right carb's air intake with my head (forcing a vacuum). however the instant I remove my hand or lower the revs it loses the right cylinder again. I believe it may have a compression issue or need a carb synch, but I would like to get some other opinions as I am a new to bike mechanics and only have so much money to throw at it.
