04 R1 high rev on 6th gear???

[MR JJ]

Before I start I just wanted to say thanks in advance.
My 04 R1 seems to loose power when on 6th gear. I'm on 9500RPM 132klixx. I thought it's was the spark plugs at first. Changed it and same problem. Put some injectors and fuel lines cleaner still same. I did some research on R1 forum and so many possibly things that may cause the problem. E.G. injectors, exup, clutch, tranny, tps, one suggested to put power commander. So If anyone here have the same problem before, how did you fix it? Or anyone here have any idea what's wrong please help me out. Again thanks in advance.

A better explanation of the problem is needed.

"High rev in 6th gear" - "9500 rpm 132 klix" - is this meaning that your engine is doing 9500 rpm in 6th gear at indicated 132 km/h? The math does not compute (or there is a critical piece of information missing). With stock gearing that bike should be doing somewhere near, or a hair over, 4000 rpm per 100 km/h in 6th gear, i.e. around 5300 - 5500 rpm at 132 km/h. This is a lock-step arrangement due to the mechanical linkage inside the transmission. This means 4000 rpm per 100 km/h means 2000 rpm at 50 km/h, 6000 rpm at 150 km/h, etc.

Now, explain your discrepancy from this. I will give a number of suggestions for you to pick from. If the situation is different then explain it CLEARLY.

1. Engine revs are 9500 rpm in 6th gear at 132 km/h AT FULL THROTTLE but if you back out of the throttle and coast back through 132 km/h then the revs are in the above-mentioned 5200 - 5500 rpm range at that speed. If this is the case, then your clutch is slipping. Fix it.

2. Engine revs are 9500 rpm in 6th at 132 km/h, and around 10,500 rpm in 5th at 132 km/h, and near redline in 4th at 132 km/h (and the engine bounces off the rev limiter in 4th if an attempt is made to accelerate much beyond this), and this arrangement is independent of throttle position. If this is the case, someone has installed stupidly and insanely short gearing on the bike. Go back to stock gearing.

3. The tachometer indicates 9500 rpm in 6th at 132 km/h but there is no apparent adverse affect on the bike's performance, the tach indication is not consistent with the audible speed of the engine, and the bike otherwise operates normally. If this is the case, then your tachometer is whacked. Replace it.

Or something else.

Explain CLEARLY.

Hey Brian thanks for your reply. You are the third person said about clutch is slipping. Sorry about the explanation, I don't really know how to explain it well.

Anyway say your cruising on 6th gear 120klixx whenever I give the full throttle the RPM goes high and the engine scream. Feels like no torque or power.

By any chance Brian. Do you live in Scarborough? And do you have GSXR 1000?

Yep, that's the clutch

Sure does sound like the clutch.

My friend had a similar issue with his CBR and it was a poorly adjusted Clutch cable.

If that checks out for you (or if you got a hydraulic clutch) then it's on to the actual clutch itself.
Is it badly worn? Mileage on the bike?
Have you changed the oil recently? Did you put in correct oil?

Ahhh yes, good points!!

Check your clutch free-play: http://www.youtube.com/watch?v=eRBGiTrpp7I

Make sure you're not using "car" oil in your bike (if you see the "energy saving" logo on the back of the oil bottle = BAD for your clutch and is probably making it slip):

That's not me, but I think I know the guy you are talking about (and by the way, his diagnostic of this problem would have probably been the same as mine).

Anyway, the other folks above have this covered. Make sure there is some free play in your clutch cable - it needs to have a few millimeters of slack in the lever when it is released before it starts pulling the cable. Otherwise, the clutch could be partially disengaged even when you are not pulling the lever. It appears that you have not used an "energy conserving" oil, either.

If the cable is OK then it's time to pull the clutch cover off and have a look at the plates inside ...

By the way, there is a good chance that if the cable turns out to be too tight and you fix that, your continued riding the bike with it in this condition has probably cooked the clutch plates in any event.

Thanks Brian again for the info. I will see what could do and keep you guys posted.

thank you

Hey guys, im 99.99% certain that i am having the EXACT same problem. like mentioned about, moving relatively fast at around 130-140km/h in 6th ( 3/8 Throttle) crank the throttle to about 3/4 and i just get increased RPMS however my speed does not increase, it does slightly 2-3km/h every second or so, but im CERTAIN there shouldnt be a delay in rpm and speed, because like previously stated, it is a LOCK SYSTEM, meaning the rear wheel is completely in sync with the clutch plates via a gear ratio, at any which point in time this SET ratio is affected, the clutch is slipping. I just answered my own question :P However i am currently using 15W-40 "Diesel" engine oil made by Castrol to the best of my knowledge its also suitable for gasoline operated vehicles. Before the oil change this problem was still present so i think if anything the new oil aided in the problem however did not solve it (ofcourse it didnt because the plates are probably F*cked or springs are pooched). I also have another slight problem with my transmission, definitely not originating from the clutch but yet, the gears. So when i shift in the first i get a reassuring clunk and the bike moves forward very slightly but rapidly (like a shake), and takes off smooth now when shifting into second i get a gear mashing and not so reassuring click rather than a crunk@!@! and this has been a problem ever since i have been in posetion of the bike, all other gear shifts from 3-6 are flawless however. So what could the problem be?
