Question about 2005 Beta RR 450
Some sort of feul/oil mixture is shooting out from the Crankcase 'breather?' tube that runs up to the air cleaner box.
I'm gonna go with theory #2 sort of. My guess is that one or more of the float valves is leaking causing the gas to overflow into the crankcase. This happens often with bikes that are allowed to sit for long periods with gas in the carbs and tank. A thorough fuel system cleaning is what it needs. I'd say go ahead and buy four carb rebuild kits for it - may as well since you'll have to disassemble the carbs to clean the gum and varnish out, which is really the best thing for it at this point. I wouldn't try to run it again 'til you get the carbs to quit leaking, the fuel drained out of the crankcase and put fresh oil in. ,,,
