Winterizing question
Last year I winterized my Yamaha ox66 by adding all the proper fuel additives and spraying fogging oil by romoving the plugs and rotating the motor. I did not remove the intake and Fog that way. Should I be doing that and if I do should I expect my o2 sensor to be fouled ?

I would fog through the intake if it was mine. That way you get a protective coating on the internal rotating assembly as well as the pistons/rings. You should clean the O2 in the spring, but I wouldn't think fogging it would kill one.

Just did my Ox66s. Sprayed some fogger into intakes while running then shut off, removed plugs and sprayed holes, turned over motors, sprayed some more, put plugs back, sprayed everything with WD40, put cover on....see you in April....
