So I had around 2000 miles on the bike and decided to swich to full synthetic. The only motorcycle oil (4t) I saw at the time was
20w-50. So I bought that at 10.50 per quart. changed the oil and filter, started up the bike and it ran like crap. Its was knocking and pinging like crazy. I let it idle for a few minutes and it got a little better so I took it out for a few miles. It knocked the whole time. It did settle down after 30 or so miles but every time I let it cool it knocked again every time I started it back up. Long story short I went back and got some regular 10w-40 4t oil, changed it again and it ran like a dream. I think maybe the engine wasnt broke in enough for the full synthetic oil. or maybe 20w-50 was just to heavy of an oil. Either way I'm gonna stick with regular stuff for now.

your supposed to wait till at least 6000km or 3500miles before you switch to full synthetic. its recommended to go around 10,000km or 6500miles before you switch though...

The oil shouldnt have caused that. Theres cars that come with synthetic from the factory. I agree with the waiting till the second oil change to switch. But id have to think that maybe you had a faulty oil filter. Or something else going on.

mine ran crummy as well when I ran 20w-50 once the oil warmed up (20 minutes or so) it ran ok. After 2 or 3 rides with the oil I went back to 10w-40 and it runs good again.

It may have been the oil filter, I changed it to. Got alot of miles on the new oil and filter and it still running perfact.

Thanks for the thread, my yamaha dealer only recommends 10w40, it may be the weight of the oil just does not get into the tight clearances of the new motor. Unless you are running in extreme heat I would stick to the 10w40. Can not imagine it being the oil filter, I am a mechanic and have never seen a clogged/defective oil filter.

I went an unconventional route. I did a hard break-in (read about how and why here: http://www.mototuneusa.com/break_in_secrets.htm) I did my first oil change at 53 miles after the hard break-in. I used regular 10w-30 Penzoil and a PH7317 Fram oil filter. That got a lot of the metal flakes out of the engine. Than at 650 miles, I went with 15w-50 Mobile 1 Full Synthetic and replaced the filter.

It's been running like a dream and I'm at 900 miles so far.

BTW - I live in southern Texas where we hit 100 easily these days. That's why I went with the 15w-50.

+1 my engine builder that builds my car engines and also my other engine builder that built kart motors for my little brother. They both always said break it in like you stole it just let it warm up first. Ive always done that and Ive never had an engine problem. Leaving the dealer with the bike was a full throttle pull till third and I havent been easy on it since. I have 780 miles now changed the oil at 698 and its running like a champ.

Hmmmm....I don't see where oil would come into play as far as the engine all of a sudden knocking and pinging?? Souds more like a fuel prob...oil don't cause that!

No, oil could cause a lot of noise, fuel problem, not likely unless you are having some serious running problems!

Well I have ran a truck out of oil before...a long time ago, and it sounded alot like that. Like running an engine with no oil or very little oil. The only thing I can say is it was all on the same tank of fuel, and with the new oil its just fine.

I used the Mobil 1 20-50 motorcycle oil and M1-110 filter on my first oil change too. Running perfect also!

I just did my first oil change an I used Castrol conventional 10W-40 and it seems to be running smoother than whatever was in it factory. I pushed the initial change a little too far I think, about 1,000 miles. The color of the oil was sure a heck of a lot better then what my roommate took out of his 08 Sportster-Nighster. I am pretty sure he maybe has changed the oil once since he bought it. Riding temps vary from 35-105 F.
