i have an 04 1K which i started with suzuki lube until 6000 miles, did oil change with suzuki syntheic ( don't know why ) the problem is i think the clutches are slipping ( maybe just in my mind ) i do know what a slipping clutch feels like but, it only seems to do it when it's cold...bottom line is i want to switch back to reg oil..what you guys think

oh the bike is at 8800 miles..so basically i did one oil change with the syntheic

Aaron what oil did you use and what weight. I switched to synthetic and I thought my clutch slipped a bit at first but I was just not used to the smoother shift transitions. Anyways if you want to switch to regular you can. It will not harm anything. I've done this in my car and it runs just as it always has.

reg oil 10/40
syntheic 5/40
i believe these are the weights not sure but, i'll check
see it's not when shifting gears, it's the take off they feel like they slip.
cool i think i gonna switch back
thanks......

Define "slip"? Do you mean is takes more lever action to engage the clutch, or once engaged the motor revs fast without much acceleration? I switched oil several times cause I didn't like the slip while it was engaging. I just wanted it to grab and be done. I was using synthetic, but went back to conventional. I actually use Pro Honda oil. (Blasphemy I know) Seems to work good for my riding style, just choose an oil that feels good to your hand provided the clutch isn't actually worn out.

And despite what people may tell you, if car oil was good enough for your bike, then the manufactures wouldn't make motorcycle specific oils. So stick with Bike oils.. The debate rages on, but if they make dedicated bike oils, why wouldn't you use it?

when is the last time you adjusted your clutch? Mine started doing this and I had to crack the side open and re-adjust the clutch.

I agree. It's called shudder. It happens when the clutch doesn't engage quickly enough. Most people believe it's wrong to have a good amount of slack in the lever. Being as I have almost 35k miles on my factory clutch and i've only adjusted it 2 times i'd say I know how it works.

I have switched back and forth from natural to synthetic oils (I was broke but not too broke for an oil change lol) The bikes seems to be fine either way. I prefer synthetic.

I use motul synthetic. Check the clutch cable too, I had a buddy who's zx6 would rev up and go nowhere while in first or second., It turned out to be the clutch cable needed to be adjusted

I've used Motul 300V a couple of times and I didn't like it one bit. I'd never put that stuff back in my bike. I've been using Shell Rotella and it's been better than anything I've ever used.

Some synthetic oils are just TOO slippery for a bikes clutch!
Sounds self defeating...and it IS!
It also depends on you bikes mileage and the current condition of the clutch before the switch to synthetic. That added lubrication barrier and thinner yet stable viscosity can actually work against a bike with a clutch that is borderline to begin with! My Triumph used full synthetic from day 1 (mobil mx4t) as it was prescribed in the owners manual. Perhaps a semi-synthetic might be a good compromise. Otherwise its off to clutch-city for a new clutch or heavier springs. Some bikes transmissions shift noticeably smoother with synthetic and some do not.
With my zx6r i noticed an immediate/pronounced difference in the transmissions shifting, in my yamaha yzf600 i did not.
Bottom line is this...If you use quality motorcycle oil and change regularly, dino-oil will be just fine. I know we want the best for our babies but not at the expense of being counter productive!

Have you guys heard of royal purple? I know they make a MC line, but was wondering if anyone has tried it. I run it in my truck and am absolutely in love with it. and believe me, i got a 75shot on it and the truck is beat on. The stuff really seems to help. Plus it garuntees hp.........im sure one of you is gonna give me the first official flame on here, but i swear they are telling the truth. I used to run mobil 1 full syn then switched to the purple. I noticed a huge differance, and it wasnt in my head. I had raced my boy from the local part shop where i got the oil at to my house. results were typical. it was close race. after changing just the oil, truck ran smooth as hell and definetly beat him more rapidly and by greater distance:dunno

I bought some royal purple from a pro drag racer friend i work with. I too have heard it's awsome. One thing i was told that kept me from using it was this: If your bike or car sits inactive for long periods of time, there is something in the oil that etches metal parts and actually does damage. I know it sounds crazy but this was told to me by the same person who uses it and SHE races a turbo busa and would/should know first hand. The vehicle i intended it for DOES sit for extended periods of time so i thought it better to stick with something more main stream!
Don't flame me either, i'm just relaying information from someone who uses the stuff inside their high hp builds!

i thought you were about to torch my ass. thanks for the confirmation though. and ya i heard the same as far as the etching. plus it lasts longer than normal. But i still change no less then every 4k. Can't get out of that habit and refuse to change. just doesn't seem right:thumbup
