Alright, most of you who rode sunday know about the problem already. Heres the deal: Through 1st 2nd and 3rd, i feel like when i fully open the throttle, that my rear wheel loses traction (like sliding on oil or wet pavement) but then catches and keeps going. Mind you this only when im full throttle. My chain, even after i had tightened had already gone very very slack, and that too i dont know why. R6Buttercup and I took my front sprocket cover off to have a look at it, because the back was fine. All my teeth are on the front one, but the lock nut and washer are very rusty and coroaded (sp). Matter of fact, i cant even get the locknut off, it is literally stuck, my last option is to go buy a socket wrench set and get a 32mm bit to try and get it off, if that doesnt work i dont know what to do.

Any ideas how to fix these problems. I already have a 520 conversion kit on order (16 tooth front, 50 tooth rear, with a 520 regina gold chain). Could it just be a i need a new chain and that its lose? Some people thought it may be the clutch, but i dont drop out of gear, it stays in gear, its just feels like its skipping or something, but like i said, i have all my teeth, any suggestions?

I know this post is all outta order, but im remember to add shit as i go, sorry

 

by what you describe i'd be fairly certain it is your clutch slipping

as for the sprocket nut i wouldn't worry, they usually put a ton of super duty loc-tite on those things, and then all that heat coming right off the motor just bakes it all together... it was very very hard to get off of my gixxer and at that time it was only 6 months old, so i can only imagine how much almost 6 years would fuse it on there

but if you want you could take out your clutch plates and measure them with a caliper, get a service manual and see what they are supposed to be, but you might as well just replace it if you've got it out, looked up a Factory carbon fiber clutch set and its only 61$ retail

 

1-may be the clutch like was stated. How many miles on the bike? How hard was it "used" before you got it? Does it only happen in the powedband (7-14k) or at all RPM's. I've only ridden 1 bike that had a clutch going and only heard it described a few times and from what I had heard it went like a car clutch did so it started slipping when under hard under gas and then slowly started slipping everywhere later on. It might be going out weird though. Get on it a few times and see if your RPM's go up out of sync with the mph in a specific gear. Just look for an open road without cars and get on it a few times while keeping your eyes on your speedo and tach. Or you could sit still and squeeze your front brake all the way and start letting the clutch out and giving it gas like you're going to do a burnout(without doing one) and see if it slips then. Just don't get to overzealous and actually do a burnout though unless you're into that type of thing


2-chain/sprockets....probably not as I've ridden a few bikes including mine that had very loose/shot chains and haven't gotten any of the same symptoms. My bro's katana had a 14 year old chain with tight spots that was about to come off the rear sprocket and it still didn't do anything weird like that. It had some surging and didn't feel right but that was mostly at slow speed.

3-that thing I mentioned the other night that happened on a buddy's R6 where the shaft that the sprocket goes on stripped out. The guy it happened to is crazyr6man on the coast riders board. Maybe cbr will know more about it. Just kind of weird it corroded on ya. You might as well check that out because you're going to have to take off the front sprocket later to put on the new sprocket(did you go down 1 in the front or up 2 in the rear when you ordered the kit?). Kinda doubt this is it though as it does sound like a clutch problem

4-I have no idea what else it could be besides the clutch or the weird thing that happened to matt. Its a weird problem and normally I can automatically guess what it is. Post up on cycleforums.com in the general sportbikes section as it gets a lot of traffic and there will be someone there that know what the prob is

 

Bah i was hoping it wasnt the clutch (mainly because im just about out of money ) But that price isnt bad at all. When i get the time, ill take it apart and measure the plates. If its the clutch (which your usually right in these situations) then ill give ya a call to order a new one I should know by Saturday.

 

I think its the clutch as well....


put it in 6th gear going extremely slow...to where it almost wants to stall. You know that jittering effect, and floor it. See if it jerks/slips

 

Before i left for work i posted my reply, and i swear Del was the only one that replied Thanks for the input Shane.

As far as riding it, well, its all taken apart right now, and i was just gonna leave it that way till all the parts came in. I kept the front the same and went up 2 in the rear, i hope that was the right thing to do I just went with what was suggested on the page i bought it from.

Anyhow, since most of you are pretty sure its the clutch, ill just have to get another one i guess. The bike has 20,050 miles on it And im not sure how hard the two previous owners rode it, but im sure that with the condition the body was in when i bought it, it was ridden rather hard. Oddly enough though, i was suprised to see that with so many miles, and the same stock chain, the sprockets didnt really have worn teeth.

When i get paid, ill give you a holler Bret. You think i should take it to the shop to put the clutch in, or do it myself, because when i read my Haynes, thats shit looked hard as a bitch Im not mechanic buff, i like changing the oil and thats about it. When i get all the parts i need, im gonna post on here for any of you guys who want to come over and help me put EVERYTHING (new spark plugs, air filter, new (used) rear caliper & rotor, and of course now-the clutch). Ill probably order some pizza and get you older crowd some beers for your efforts

 

where are you located?
i have a R6, i could probably take a look at it for you?

check your tire pressure,
i had a similar problem to what you described,

i was running 31 psi on the rear and it felt like the rear was loosing traction through the first 3 gears when the throttle was wide open and the tires developed tire boogers really easy(sign of low tire pressure on race tires). I rechecked the tire pressure with 3 other guages and they all read 24psi!!! apperently my buddies guage was defective.

i put the pressure back up to 32 psi. and the symptoms dissappear.

 

Yorktown.

Back when the tire had 32 psi in it, and it was doing the same thing, so i upped the tire to maximum load pressure 42 psi, and it actually stopped for a little while, but now its back to doing it again. Ill check and see if air was lost over the past few weeks, if it was, it MIGHT be the problem.

**edit** just checked the pressure, its 39 pounds , guess its the clutch.

 

It shouldn't be too hard. Just make sure you soak the fiber plates in oil for a while before putting them in, I sold a guy a set of clutch plates for his bike the other day, came back in the next day and said they didn't make it 10 miles down the road because he forgot and put them in bone dry.

 

from the way you described it, it doesnt sound like it's the clutch to me.
if the clutch is slipping than i dont think you would lose traction when you open the throttle wide. If your clutch goes bad, you would probably not get all the power to the wheels and the clutch will have a hard time engaging.

i would go with the chain/tire theory.

Get someone to follow you to see if they can spot anytype of problem coming from the bike.
