Start up noise and white oil residue

[jonkawasaki]

Picked up some new oil today.  Was intending to get Motul 300V fully synthetic.  Supplier said it was racing oil and not designed for road use and needed to be changed every couple of thousand miles.  So he recommended Motul's best fully synthetic for road use (I forget the actual name).  Then I mentioned I was currently running semi synthetic.  So he said .... don't replace semi with fully synthetic as it can cause clutch plates to slip in some case and that if I wanted to change to fully synthetic then I should have the clutch plates changed at the same time.


What do you folks think about his comments?


In the end I ended up going for Motuls best semi synthetic  (7100 I think it was).


I was really keen to give fully synthetic a go but he really put me off.

using fully synthetic oil as been known to make clutches slip in some bikes that the recommended oil is semi 10/w/40 that's why we stop using fully synthetic oil in our work bikes, which were Honda's ST1300. I just use a quality 10/w/40 semi which I've always used in all my bikes including my G.T.R 1400 and presently in my zzr1441 10/w/40 semi is the recommended oil and is fine and well up to the job, I change my oil and filter every 2,500 miles and use Castrol G.P.S power 1 with Trizone Technology "extreme protection" 10/w/40 semi synthetic. you would be ok running your bike up to 4,000 miles if your doing long runs most of the time, if your on short runs change it between 2,500 and 3,000

Jonka,

I agree with your dealer Don't do it !!
Other problems with Fully syn is as the oil is "thinner" engine noise can increase (not good when your worried about the camchain) also you will lose the oil "wedge" (stickyness) as 2 kwacks has stated 10w/40 semi is perfectly adequate just change it regulary and it'll be fine, PS I work for Castrol (industrial so not I cannot get oil for bikes) so I have knowledge of lubrication systems and have the ability to contact developement chemists for advice if needed (a few years ago I spent a very interesting evening talking to a chemist about oil for GP bikes after having a tour of the workshop facility, brilliant

Quoting mishap! 

Thanks for the advice though I'm sure it'll work out!

unless I'm very much mistaken motul 10/w/40 7100 is fully synth not semi synth, motul oil is as good as any other, but motul 5100 is the semi synth

I have run 300V in the GTR before. No issues.

the bike's oil specs say nothing about semi or fully synthetic.

you can run any oil you want in the GTR , as long as its 10W-40 and meets the JASO/MA specs.

You simply do not need fully synthetic oil in your bike, its only good for bragging about at bike meets.

If you have been using semi-synthetic then continue to do so and under no circumstances should you mix the two

Modern oils are light years ahead of oils from yesteryear.......................USE SEMI SYNTHETIC 

follow 2kwacks advice..he is correct

The kawasaki dealer that supplied my bike changed the oil to Motul 300V at around 700 miles, as the "jolt" into first gear became too much for me to bear (my previous BMW was completely smooth). This was done under Warranty, paid for by Kawasaki and the dealer said is one of the recommended fixes if a customer complains of harsh engagement of first gear.

This change transformed the bike, at the next oil change Motul 300V was also used and will be again in the Spring, when the 7,500 mile service becomes due. There has been no oil usage between scheduled services and I definetely feel that the extra cost is justified, at least for me. The clutch (at least on my bike) shows no signs of slip, although before the Motul 300V was used the original oil was, I presume a semi synthetic. Clutch plates have never been changed.

The Kawasaki dealer that I use now offers this oil on scheduled services to GTR owners...

The first dealership which used fully synthetic on mine was Autorama at Batley, they said they always used it. I'd no issue either way and to be honest I had no clutch slip with it and I thought it ran smoother on fully synthetic. I've just replaced my oil and a different dealership said that semi synthetic was just fine so that's what I'm using. Personal choice at the end of the day, but ultimately semi synthetic will more than suffice.

I'm going to stick with the semi that I bought yesterday but might try fully synthetic next time I need an oil change.

did you I've more than the normal first gear clunk? the reason I'm asking is because, Kawasaki's clunk in first gear it's Kawasaki's trade mark "cluck every trip"

Well, the Service Manager tried two other bikes whilst checking mine, and I was there with him. One was a demo, with around 1,700 miles on it, the other a used example with some 9,000 miles showing. The demo was almost silent when engaging gear (as was mine from new, for a short while) and the used bike was similar to mine. They bled the clutch on mine first of all, with no improvement and then one of the tech's said change the oil for fully synthetic, as Kawasaki recommend in these cases.

Following this oil change, the excercise was repeated and mine was almost (but not quite) as quiet as the demo bike. It has stayed the same since. The tech said that the fully synthetic oil flings off the clutch plates more quickly, allowing them to free faster rather than drag.

very interesting indeed   will do a bit more research into this are you saying Kawasaki tech department said use fully synth instead of semi synth which will eliminate the first gear clunk. in which case, this begs the question? why Kawasaki didn't use fully synth in the first place, after all... Kawasaki knows about the first gear clunking! this is very confusing

The tech said that there were a range of "fixes" from kawasaki that were to be applied when a customer complained of harsh engagement of first gear. Bleeding the clutch was first, with a change to fully synthetic oil next.

I suppose that if Kawasaki insisted on fully synthetic oil at service intervals it would increase cost of ownership? When I worked for a vehicle manufacturer some years ago, everything possible was done to achieve the lowest cost per mile figures

... wishing I got the fully synthetic now
