I now have just over 2,000 miles on my 2003 zx6R. This will be my 3rd oil change. The first 2 oil changes were 10w40 dino oil. But I live in a very hot climate where the temp. is already in the 90's and its just the begining of the summer, and I do a lot of racing and hard riding. Can I go to 20w50 yet? Or is it too soon? Also can I go to semi-synthetic oil yet. I have been putting MOTUL 3000 natural oil, but I would like to go up to MOTUL 5100 semi. Is it too soon? Aslo is 20w50 too thick for a brand new engine?

You could use the 15w40/50 heavy duty oils. It's normally used for trucks and can take one hell of a beating. You should read this post /forum/topic.asp?TOPIC_ID=2990

Yeah, maybe your right. I am going to start changing my own. I don't have a choice which dealer to bring my bike. We have 1 or 2 of every motorcyle dealer on the island.

I told you the dealer put in the 5100. If you don't believe my mechanic call yours. They haven't given me any reason not to trust them. Also, if anyone says that is too soon for semi synthetic show me the proof.

Read your manual. They should NOT have put any synthetics in your bike yet. 600 miles is WAY to early for that. Thats common knowedge I have no idea why they would be such a dumb ass.

When you feel you're ready for synthetic. Use Mobil 1 Synth Motorcycle oil. The regular just Mobil 1 may give you clutch slipping problems (since it is energy conserving motor oil with friction modifiers) so stick to the motorcycle type. I personally wouldn't use synthetic until like 4-5k miles though. Technically I think you could put in synthetic right now though without any problems.

Mobil 1 15w50 (car stuff) is not energy converving. It is probably one of the better oils out there. Thousand of sportbikers run it with no problems.

It is hard to say, but most people think that full synthetic is too much period. Semi at the most. Full synthetic may help you for shifting, but from what I understand, it can cause clutch slippage. If you feel comfy with your dealer, go with it. You seem irritated at some of the suggestions on this post, but everyone has an opinion, and I don't feel that anyone in here would give you bad advice on purpose. If you are in question, go by the manual as suggested before. Good luck!

I understand that full synth is beneficial at higher rpms and higher heat (ie/ harder riding), that's why I'm going to be switching to full synth (or at least semi synth) at 2000 miles or so. Might do semi-synth first and finish the year out on it, then switch to full synth the following year.

Full synthetic will not cause the clucth to slip. I most certainly makes the tranmission operate smoother and by most reports will give about a 1% increase in hp. The down side is that it cost more. Semi-synthetic whould be better labeled not-synthetic. It can be labled semi-synthetic if they add one drop of synthetic oil to the regular oil. You need to either use synthetic or mineral oil. Semi-synthetic is just a marketing ploy.

Sirigano... Exactly what happened to you happened to one of my friends except the dealership put in FULL synthetic oil at only 600 miles. He was really lucky he caught it or he could've ruined his bike. His clutch also was slipping like crazy. He changed the oil but it still slipped for about 2 weeks after the change. The synthetics are so damn slippery they coat things internally and take a while to get off. He then changed his oil again at 3 weeks just to make sure all the synthetics were out. So basically the dealership could've ruined his bike and they cost him an extra 2 oil changes. Just one more reason I hate Stealerships.
Go back to your dealer and demand they change it again at no charge. Also, I ould notify kawi if you have any problems because I think use of the wrong motor oil could even void your warranty.

The dealer put full synth in my bike at the 1000km service. is my bike f*cked or what? how does synth oil damage a new engine. is the damage irreversible?

Your bike will be fine. Porsches come from the factory with synthetic. At 1000 km the bike is broken in for all practical purposes.
