I use Motul 5100 10W30 Semi Synth in my CBR. Used Silkolene in my NT650 but they don't seem to do 10W30 so I use the Motul instead. It's good oil. Is it not available to you foreigners?:D:D

I'm pretty sure the oil you use is avaliable....but at the time my bike was at my local Honda Dealer and I asked about full Synth. So used what they had on hand..so far I like it.

I note Motul 7100 (Fully synth) is available as 10W30. I may use that when I've finished the 5100.
Never trust what a dealer uses unless I was to see him open and use a new bottle. You may have more faith in your dealer.
Safe riding.:)

Like the Motorex & Repsol oil brands, Motul oil products are available here in the U.S., though you're not likely to find it on the shelf anywhere other than a well stocked motorcycle dealership, or at a Cycle Gear store. Even Bel-Ray, which is a well known U.S. based motorcycle oil company, isn't something you'll find at the auto parts stores. But you'd be hard pressed to find a motorcycle dealership in the U.S. which doesn't carry at least some of the Bel-Ray product line on its shelves.

I was there..when the filter was changed.....when they opened the bottle...... when they poured it in...

Food for thought. I wonder if you are in Bangkok, Jim and can recommend the best Honda dealer for servicing in the city? I always get a changing experience when I get "Ceeby" serviced.
Sorry Matthew, but I can only recommend for Chiang Mai. Personally I like doing this myself anyway - it really is very simple, and always a reliable experience!

I should also add, I am now 2,500km since the switch to 100% synthetic Shell Advance and I can confitm that she sure runs smoother - the engine "sings" at high revs. No going back for me.

Guys sorry to ask what is probably a really dumb question. I'm new to bikes and I have a 2015 cbr300r and I too have this cam chain noise at 5k rpm through to about 6500 rpm. Is this harmful to the bike? Honda have been of no help in fixing in. So basically do I need to worry that while I'm riding on the highway at 120km/h or about 85mp/h is my engine goi g to eventually cease or blow? I'm going to try the change to full synthetic oil as suggested. But in the meanwhile is this a major concern? Thanks I appreciate the time to answer this.

Welcome Bryce, firstly how many kms are on the odo of your bike? It's a 7 yr old bike now so if the mileage is high then possibly your cam chain tensioner is worn out and needs replacing but if this was the case I'd expect the noise to be present through out the rev range more and at idle.. If it's not a high mileage bike and has been regularly serviced etc then perhaps this is just a quirk of your motor. It sounds like maybe you havent had the bike long so has it always sounded like this?
My opinion is that you have little to lose by trying the full synthetic oil.

Thanks for the welcome @kiwi rider much appreciated. My bike has 18000km on it. Yeah I only have the noise at 5k rpm through to about 6500rpm. Nothing at idle. Ive only had the bike for 4 weeks now. It’s been there from about the first week that I noticed it. I don’t drive often on the highway mostly main roads so I average between 80km/h and 120km/h. Mainly around 100km/h. I live in South Africa so climate here is fairly warm. Even in winter. I’m unsure of the service history. It was bought from Honda and they serviced it before I bought it but then again dealerships are as dodger as private sales nowadays. Bike doesn’t seem to get hot according to the gauge (stays at 3 bars) or half way once warmed up touch wood. It’s just that noise which sounds as if it’s coming from under the gas tank. But I can’t say for sure as it only happens when riding. I can rev it up when stationary to 5k and I don’t hear the noise. I’m going to try full synthetic and see if that works. Just kinda terrified the engine blows while I’m riding and I wipe off the bike.

Unlikely scenario but if engine noise changes dramatically then keep a couple of fingers on the clutch lever ready to pull it in. It would only be if you had a transmission lock up that the bike would be uncontrollable until you came to a stop. Not common.
Keep us posted on the results of the oil change.
