Hi I just got a 2001 YZ80 I have a few questions that hopefully someone can answer. I’ve been trying to decide what plug to run I ride in my yard a lot so the bike doesn’t get held in the power band long however I do also ride at my friends farm and at on the railroad tracks but not as often so I’m trying to weight all of this when selecting a plug, I’m not sure how hot to go. Right now it has a 9 in it and the stock plug is a 10. Also I need to change my gear oil, the local Yamaha dealer sold me some 80w maxima gearbox oil but the service manual I just got for the bike recommends 10w-30 or 10w-40 what should I use? And my last question is about air filters, I’m more concerned with protecting the motor then I am with getting every possible ounce of possible power out of it and once again I’m am unsure of which brand of filter to buy for my application. Thanks in Advance for any responses.
