Understanding that the engine runs rather lean from the factory, today I installed an EHS fuel controller and set it up appropriately in regards to my current configuration. Understanding that engine break-in will contaminate my oil with metal shavings, I changed the engine oil over with a new filter and some Rotella T 15w40. I also installed a "gold plug" for good measure. I’ll change the oil over again at 200 miles as per the schedule in the owner’s manual (I’m at 32 miles now). I’ll change over the diff oils and install gold plugs as well shortly (didn’t have time to get that done today).
One concern that I have is in regards to my warranty. The oil I used appears to meet Yamaha’s spec for viscosity, and is JASO-MA classified, therefore should be perfectly safe for wet clutches. The dealer recommended Yamalube (of course). The dealer insinuated that not using "Yamalube" *could* cause issues should I require warranty service. I meant to e-mail Yamaha (and get a response in writing) however I can’t quite locate an e-mail address to use for such purposes. Is there a consensus on whether or not it’s OK in the eyes of Yamaha to use other brands of oil, providing it meets the specs stated in the manual? I’d find it rather ludicrous to be tied to an obviously overpriced (not that it’s such an issue) and almost surely inferior (this being my main concern) oil.
As previously stated, I also intend to change out the diff / final drive oils and install gold plugs soon. I do have a quart of "Yamalube" which I intend to change out within a day or two, then follow up at my 200 mile service with something better. I’ve read many use Amsoil. I’d be open to recommendations for other oils for use in the diffs though.
I’d also like to install some grip / thumb heaters before the end of the year. I know there are a number different options (heat demons, moose, some other brand that’s not coming to mind). They all seem to be within roughly the same price range. I’d be interested in any input regarding which choice may be best and if there are advantages / disadvantages from one brand to the other.
Thanks in advance for any input offered. Photo added because, well, why not!
