I did my 2nd oil change at 2500 miles with Golden Spectro 10w-40 full synthetic. I have about 1000 miles since that oil change. I have noticed that if I'm rolling in 3rd or 4th gear and go to wide open throttle the bike doesn't pull very hard at first. It feels like the clutch isn't grabbing all the way at first. I know this is like an age old debate over synthetic oil in wet clutches. I was just wondering if anyone else has noticed this when using synthetic. More importantly can I just switch back to non synthetic oil without any issues ?

I looked up your oil on their site... it says its JASO MA compliant. I believe that's what must be met for wet
clutch applications. What I didn't find was info on their Zinc and Phosphorus levels... these are extreme pressure additives...
and high levels will invite slippage. If that is the case.your friction linings will be contaminated.

I run Mobil 0W40... the zinc and phosphorus levels are slightly LOWER than Mobil racing 4T motorcycle oil.
Mobil has a chem chart on their site.

if you have got clutch slip, you really should notice, if it lets go, your revs will climb hard, but your forward motion will not change much,
i have never expierienced slow clutch slip, only full on slip when engine is cold, or not up to full operating temp, and has only happened with fully synth,(not on this bike, others) unless plates were actually beyond useable
can you feel it let go? or bite again if /as you let off the power?

id stick with what the man in the web below says

Leave it in. Don't rev out till a few more hundred miles. Yes, I ran full, did slip at high rpm, but with miles, the slip went a way.

Gadson was experiencing a drop in et's in the 1/4 with traction control off,it was due to the flys closing,I think Wheelie or Brock can give more info

We have yet to be sure he actually has a slipping clutch.
Do you think his oil turned on his ktrc?

Generically, we know how stout kawi makes a clutch pack. I'm using the 2+2 method. "The Hand" has beat bike significantly to add 1 being the bike has low mileage, is new, has thin said it. Part 2 is I've generically installed all sorts of straights and mixings so mixed up, I did find mine slipped. But after, that is how I do not need a bike to know simple things like:

#1. Syn: is used is think what you last did to the bike?
#2. New: only year hair dresser knows for sure.

We have yet to be sure he actually has a slipping clutch.

No. Butt I wish someone would find out that does have the R... That is how I read that is englishit, write?

Hey GRN... I don't ride with KTRC on. Usually going WOT from 5500-6500 rpms. She just doesn't feel like she grabs right away when you crack the throttle but we will see. Riding it tomorrow will double check the rpms. If I feel it's still doing it I will switch back to non syn and see if it makes a difference. Intruder alert man you guys are paranoid !

Intruder alert man you guys are paranoid !

Paranoid changing oil and then it slips? If you are a veteran oil changer/discussion... Do what you want. I am just saying, if you keep heating the oil to breakdown what will eventually go away, one would stop being so paranoid it will do some harm. Relax on the throttle and run it around for awhile. Because you'll back off when it chatters or slips.

It seems you need to go out every time and nail it. Your bike of course. Your time in the saddle. I'm saying, work with the oil. Become less paranoid about what I've already done in a way that when I speak, you now open the wallet wasting a perfect round oil. The whole point is longevity of moving part.

Just trying to desquid the kind of paranoid riders that are out there changing their oil. Still talking about dropping oil, wasting reserves, because he has to wring it out. Not watch it happen go away in awhile. Well, isn't the best oil to have in a high spinner is syn? YOu are going to dump the oil because your paranoid? Your words.

COOT and ROOK suck this in. They may be laughing. I'm sure not paranoid about you starting an oil thread and now, are you going to prove me wrong? I want to be absolutely wrong before I speak. That means I did my homework. I'm up in that range as well. A lot. So, I sort of seat of the pants dit.

See if I'm paranoid changing oil and sort of proving your same slip. In other words, if you have to spin it up tomorrow, can't wait, simply drop the oil, leave the filter alone. That little bit will help more than hurt now.

JMO...

This is a diff situation, but I had a Seca turbo that I turned the boost WAY up on, I was getting bigtime clutch slip when I went to full syn in it. Thats usually when you'll have an issue with a clutch slipping on full syn....when the clutch is getting WAY more power than it was designed for, like a turbo 14 running syn on the stock clutch, or an old clutch on the way out with lots of hp put to it. A stock or just bolt on 14R should have no clutch slip with full syn, unless there's a clutch prob.....or maybe you're mis-diagnosing it like a few have suggested. Tire spin among other things can sometimes feel like clutch slippage.

"Do you think his oil turned on his ktrc?"...straight answer...no,I do not think his oil turned on his KTRC .I wasn't suggesting that...you figure it out.You have a 14R...right?
Point being, know all the variables before you try diagnose, no?

"only full on slip when engine is cold, or not up to full operating temp",.....in 24 years you've never experienced clutch slip except in your two scenarios....24 years?
is that for me??
i am referring to specifically slip in a 4stroke with a clutch that we presume is not worn,
lots of clutchslip , especially in the 2stroke i have owned
im directing my clutchslip expierience specifically to a situation where i can honestly say it was related to fully synthetic oil numbnuts, i am not trying to clutterfuk the man with millions of scenarios,
look up methodical,
if you have loads of encounters with slipping clutches in your time, why is that? wrong oil? not using clutch properly?maybe your bent axel was fuking with your ktrc

yet again you have veered away from the mans issue and created your own gravitational pull, Sir Isaac would be proud of you

Gunsurgeon, id be suprised if its wheelspin you got.

GRn, where did i say i have only expierienced clutch slip in TWO scenarios??? you are makey uppey man again???
reading between lines, where there is nothing to read,

i asked the guy if he notices the clutch letting go/revs climbing, i am trying to get a better idea of what going on, and to encourage him to look/learn/feel for whats happening ,
you on the other hand are jealous, you want a reach around too?

if you would like to start another thread about how many clutches i have fuked in 24 years, go ahead, oh and while we are at it, 26 years since i got my first bike, you know how i like to fill threads with shit thats not related to anything at all, it was yamaha rs 125, then a suzuki x7,then an rd 80, all of these went tru clutches, but i must have put at least 5 in my rd 350 lc, and i never heard of synth 2stroke oil back then, and when i did, it was way too fukn expensive for me,
does your seat on your R make noise? as you sit on it? mine squeaks as it rubs off the tank, its annoying, do you think i could get something to lubricate it? im not sure what to use, maybe the paint on the tank of the R is different maybe its the synth fibre of the seat any ideas?

OK... a little more info. KTRC OFF, Flies out, full operating temperature. I will found out more when I ride today to work. It could be tire slippage. I didn't really think of that do to the fact I'm usually already between 60-80 mph when I go WOT. The stock Metzler does have about 3500 miles on it. I have a fresh Metzler M5 190/55/17 in the garage maybe I will throw that on this weekend.

cool, it may well be tire slip, but im guessing at that speed and you go WOT if your tire is spinnig up, you should know about it, either when it bites,or starts stepping out,

i see MR Hyde has come back, why all the abuse? all i did was point out your mistakes regarding what i posted, ie where i found clutchslip, and you reply with name calling, ok i called you numbnuts, but seriously, scumbag bitch?dicksmoker?bitchtramp slut, have i hit a nerve somewhere? was it the reach around?
if you are going to distract from the op question by disecting what i post, at least get it right, or expect retaliation.
I can assure you I am not Hub

lmao, i aint hub, would you care to put a little wager on it? and i will do all you ask to prove it
your anger is clouding your judgment padawan
you are fixated on HUb, which leads you to think my posts are aimed at you, or something, so you cant help attack everything i say, thats quite sad

Hub was right, look at all the smoke in guns thread, well done, be proud
