Hello all!
I'm new to this forum, I am more of a 4 stroke chopper guy and spend my time on those associated builder's forums. However, I recently acquired a 2000 Beta Rev 3 250 to fix up after a long 3 year indoor storage. The bike was not properly prepped for such a long storage, so I went ahead and did the usual steps in reviving a neglected machine. Truth be told, this is my first foray into a 2-stroke motorcycle (I'm a city kid).
The Beta in question has very low miles, but was put in storage with fuel in the tank, so I did the standard maintenance as listed below following recommendations from previous Beta threads:
Drained tank, replaced fuel line and filter
Changed crankcase oil with Mobil1 10-40 synthetic
Changed coolant with Dex Cool
Premix 93 octane with Castor 927, 70:1
Rebuilt Mikuni roundslide; factory jetting and middle needle position
Replaced air filter and intake manifold with new genuine Beta parts from Lampkins
Reeds looked ok so I left them alone
Replaced plug with new NGK BR7ES
Replaced chain with a new 520 trials chain
Flushed brakes and clutch
After all of this I confirmed spark, then filled the tank w fresh premix and the bike fired up on choke after one kick. I pulled the silencer to replace the packing and left it off for the first run.

I'm wondering if the Beta guys can tell me what they think about this idle? Motor is popping, but from other Beta videos this seems to be normal. It seems a little thirsty and seems to struggle a little when I give it gas, but this improves the more I start it and as the engine warms up.
Does this idle sound right? Also, would anyone care to suggest a proper mix screw setting for this Mikuni?
Any suggestions are greatly appreciated. Thank you for your time!
