[ice man]

hi iv just taken of my air filter(pancake type)
and in side the air filter and the carb theres a black almost oil like sticky mess should there be???

if so cool
if not how can i stop it thanks :? :?

 

[uber cool]

Does the crank/oil filler breather feed into the air filter? If so could be breatherig heavy. Clean it all out with carb cleaner and monitor.
