ZXR400:This happened today

[HurtMePlease]

A few problems maybe some of you could help put my mind at ease this bike is a ZXR400L2

Ok on the way to work I pulled up to the lights to some pratt who wanted to race, usally 90% of the time I ignore them but this pratt was asking for it revving his engine and looking over at me. Anyhow I decide I'll do what i usally do, act like he is winning then pull up along side look at him shake my finger at him then zoom off into the sunset

Anyway I let him shoot off and then I blast it to 50ish then try to change up to 2nd but I miss and hear this grinding noise as I try to engage 2nd gear with the revs so high it doesnt happen I try it again and didnt happen did it again and finally in it goes. I've missed a gear once in a while but was wondering if theres any damage that could have happened there to the gear box? I normally ride sensible and treat my bike well but I'm worried that something could have had its lifespan shortened.

Also is it normal that when you conk the bike into gear the rear sprocket moves slightly even if the wheel does not? i have also noticed that the slack in my chain has increased.

Finally I have noticed that theres a ticking noise that has become worse like a clattering noise also theres a noise when I come off the throttle like something catching, I think the camchain will need replacing? though I'm unsure how much this is going to cost I know some of you have had this done to your zxr4's already so any input would be great

Cheers lads/ladies.

The grinding noise sounds painful but unless it jumps out of gear now or anything odd then it should be ok.
The movement is the cush /crush (which 1 is it?) rubbers are worn. If you take take the sprocket carrier off the rubber bits in between that and the wheel, nothing to worry about.

Can't help you with the cost of the cam chain because I haven’t had it done! Sure it's not the valve clearances though?

[Flip]

Cush rubbers are about £20 - £25 (improves the riding sooo much) wouldn't but a second hand one though.

Ticking is probably valve clearences but could be the cam chain. All engine work is expensive.

I wouldn't worry about the other.

If the slack in the chain has increased - tighten it.

sounds like you've got a bit of sorting out to do!

changing gears with high revs isn't a good idea unless your bike is fitted with a quick shifter and is highly tuned for racing! it may have been that you popped off the clutch too early, say halfway through the gear change and the gears hadn't engaged probably. doesn't sound too healthy for the bike but i'm sure you won't need to take the gearbox apart and inspect it.

as for the rear sprocket, tighten it up a bit. my chain jumps when i conck it into first gear, not off the sprocket or anything but it's never made my sprocket move.

clattering sounds like valve clearances like zxr400er said, if you're not careful this will really do your engine in. my friend had the same problem, and despite my warnings, his engine got a little bit too warm. as everyone knows when things get hotter they expand, so, my friend revved his engine a little bit too much and put the valve straight through the top of the piston! instead of getting new piston and valves etc he just bought a new engine off ebay for 140 quid and we're getting him back on the road!

Nah, nail the f*cker and practice clutchless shifting.

most people who ride ZXR400s aren't exactly pro bikers and aren't gonna be able to do clutchless changes properly, i mean i do it every now and again but only cause i engage the quickly and really ram it up rather then taking ten seconds or so to change without the clutch!

[lilredmachine]

Excuse me, but the guy in the 'fast' ford that I left at the lights on my 125 can vouch for me clutchless shifting. It really doesn't take much skill. gun it, roll off throttle, pressure on lever then pop the gear and get back on the gas. Most if not all riders from 125 upwards are capable of clutchless shifting, and most 400 riders are experienced bikers that enjoy the merits of a tiny machine they can chuck around, far quicker than a 600, not necessarily amateurs.

Clutchless shifting is harmless as long as you only do it on the up.

Look at the zxr riders defending themselves. That's right there's more of us than you so stfu.

I've been riding for 1 month on my little ZXR400 and was clutchless shifting after a few days.
It's easier than using that clutch lever thing when you're hanging on for dear life.
Only do it from 2nd gear upwards otherwise it's harder to get away with.

[quacker_boy]

i don't like this forum! everyone attacks me whenever i say anything! i ride a ZXR400 as well! i'm still just a kid as well! i'm 17, i'm in the same position as most other people riding ZXRs so give me a break!

[akaDAVE]

Sorry fella. That wasn't meant as an attack.

Christ almighty I've just realised I'm nearly 10 years older than you and I'm only 26! I thought I was just a kid!!
When I was your age, the only clutchless shifting I was doing was on my mountain bike.

stop talking bollox then

Little off topic, but damn ric's zxr is a fine looking work of art.
If you ever crash it or have it nicked, don't tell me, i'll probably cry!
