Clutch Biting faintly

Hi Guys,

A friend of mine has the exact same bike as me...a GSX-R 750 K6. Both of us have been practicing wheelies alot and needless to say, but he is still having some trouble with them.

Problem he is experiencing now is that when he rides in 1st gear and pulls the clutch, the clutch works, but something weird happens when he revvs the engine a bit. It's as if the clutch is not completely engaging....difficult to explain...I took it for a spin and it feels like it's biting very faintly when you pull in the clutch...no slipping. The bike is clutched, but when you revv it...it sounds and feels as if there is a faint bite....sheesh I hope you understand....

When the bike stands still in 1st...clutch and revv..then it's fine...only when the bike is moving.

This also happens in 2nd gear.

Someone said its the steel plates that are faintly bent, coz of the practing wheelies....dunno how true this is though.

Your advice would be appreciated.

I think those have slipper clutches. I also heard they need to be adjusted every now and then.

Yep...slipper clutch. Do you think he needs to worry about replacing clutch or anything worn bcoz of wheelies?

I have replaced my clutch...and it didnt do that at all when the plates were worn....it was slipping really bad when mine went. Nothing like he is experiencing...

Does anybody know what needs to be adjusted....?

Have you tried a GSXR forum? I've just heard of them needing their slipper clutch adjusted.

Yup. The stock one. No problems here. I put a little too much faith in it on the track sometimes. I shift into first at around 70.

I assume downshifting.... dude, that's what the brakes are for.

I have to compensate for my mid-range. I'm braking hard, blipping the throttle and down shifting at the same time. I have to take the turn in first to get good pull out of the corner. If I'm in second, I won't get as good of pull. I enter the corner at 50-55 mph.

Turn 3:

How fast do you redline after pulling out of the turn? Cause you're NEVER supposed to go into a turn downshifting into first... Thats how highsides happen. Try going in second and carrying more corner speed... Then again I'm using DOT Race tires, u might need to do it diffrently. And my slipper clutch is my two left hand fingers, that I use for clutching...

it was a track day. good for learning different techniques. next time, try redlining on 2nd instead. choose which one is more confidence inspiring. also, avoid late braking unless you are trying to pass someone.

love that redline, makes you look like rossi.

I do all my shifting before the turn. When I get into first, I brake for like a second more, then initiate the turn. I'm going in a straight line while downshifting and I often trail brake on the long turns. And my bike red lines at 16.5 (17.5 displayed). I have enough time to get into second, just in time for the chicane and I enter turn 4 in second. It's an increasing radius, so I can really open it up in second. I also take 5a and 5b in second. The turns I take in first are 3, 7, 9 and 10.

There's a video of our last track day, but the link's not working. It would give you an idea of what the turn's like.

Oh and if I took that turn red line in second, I would be going over 100. Definately not going to happen.

I thought the R6 redlined at 18k on the 06 model. must be a mistake I made in how I looked at the tach.

I would say it just needs to be adjusted... practicing wheelies is very hard on the clutch and the forks!

17.5 on the tach. It's 9% off though. The true redline is around 16.5. They fixed it for '07.

that's not 9%

9% would be close to 15.9, 16 is in the yamaha statement.

Dear Yamaha Customer:

Yamaha introduced and marketed the new 2006 YZF-R6 motorcycle with a red line limit of 17,500 RPM, as indicated on the tachometer. After testing production units, we have determined that the actual red line limit is approximately 16,000 RPM, resulting in a tachometer error of roughly 9%. This has no affect whatsoever on the performance of the motorcycle.

We are extremely confident that, despite this error, the R6 will more than satisfy you in every way. However, if you are not satisfied with your motorcycle because of this discrepancy, we will repurchase it and will reimburse you the entire purchase price, including any setup fees, taxes or interest that you have paid in connection with your purchase of this motorcycle.

If you choose to have your 2006 YZF-R6 repurchased, please check where indicated below, sign this letter and return it to Yamaha Motor Corporation, U.S.A., Attn.: 2006 YZF-R6 Buyback, 6555 Katella Ave., Cypress, CA 90630 in stamped envelope provided. Yamaha must receive this letter indicating this choice by March 15, 2006, or we will assume that you have decided to keep and enjoy your motorcycle.

Our goal is to ensure your satisfaction, both now and in the future. We would like to sincerely apologize for this error and any inconvenience it may have caused you, and also to thank you for your continued support of Yamaha.

Best Regards,

Dennis McNeal

Yamaha Motor Corp.

Regardless, it's still the highest reving bike ever. Production wise.
