Still pottering. Replaced 3 wiring connectors which wouldnt come apart due to corosion. Cant have helped anything. Flushed coolant and fully cleaned out horrendously dirty thermostat housing. Painted subframe and headers. Fixing speedo bracket and mounting as it is bent. Replaced fuel pump and filter. Removed all old alarm wiring remnants from last owner. Disabled the air pump emissions exhaust system thing as a test to see how it goes. New chain and sprockets to install along with front and rear wheel bearings and carrier bearing. https://uploads.tapatalk-cdn.com/201...e6cf198f9e.jpg https://uploads.tapatalk-cdn.com/201...2f4a425403.jpg https://uploads.tapatalk-cdn.com/201...5ab7b142a8.jpg https://uploads.tapatalk-cdn.com/201...1833555b39.jpg

Cool garage time mate

Too hot to ride anyway

Good to change the coolant, doesn't do the aluminium any good if it's old
Replacing corroded connectors is priceless

they usually fail just out of town, just on dusk, just before the rain starts...

P.S. Have you got a pool running? I'd put a dozen on that old alarm...

Oh... keen for the alarm you mean? Long dead and removed. Way back pre 2010. Just lots of old wiring left, which is now out. Yay

Haha betting pool, sweepstake. I would've put money on the problem being the old partially disconnected alarm

Indicators and power basically. Immobilisers were long removed but the loom wires were all still in there, just laying around.

[QUOTE=WanaGo;1131081902]Hey,

Ive had my ZX9R since 2005. Back in 2012 it developed a whine at 80km/h, and it had some use between then and 2014, but was then put away till only a few weeks ago. Pulled it out again, dusted her off, fully cleaned out the tank and carbs/o-rings etc and it flew through its WOF like a champ.
However...
The noise at 80 is still there.

My cbr 900rr started to get that was all the time though cam chain usuallt at 3000-4000 and thats a rattle .

With the cbr fireblade i think it was the output shaft end bearing so i striped it down year ago yet to but it back . if you pull in the clutch it still makes that sound . to me it sounded like was around the clutch bottom of the engine.

Its something thats spinning or turning it be gearbox drive area for sure.firgure out what rpm it is might be top gear gear bearing . even if you
rev to that rpm in that gear in netural it might not make a sound . as its not under load.

My nephews kawaski ninja 250 started making s sound like that was bloody lound. my dad got it service and it fixed it . i checked the chain chould firgure it out . take of you front sprocket cover and feel if the srpocket is loose or its wearing a grove in the allow cover .

The honda wasint a lound sound just anoying . no worse than the clutch rattle . which turned out to be clutch basket springs loose.

What about things like bushings or the needle bearings, 92028A and the 2x 92046 ?

Thanks

Am just going replace all the bushing bearins think comes to 300.00
For the fireblade dont see the point not. i cant be arsed taking engine out again. the gears that arent splined . and i guess isitn the worst thing for drive.
As they free wheel . am still anal about replacing them anyways.

I brought a second hand set complate gearbox and shift forks as well.
AS mechanic at honda said one of mine was slighty bent. really expensive
To buy new . and alot the gears arent availble new and real expensive if they are. i managed to get one double gear brand new of ebay . very cheap.
I guess older models not so many people want buy the parts.
I get the some gears under cut . so it wont jump out gear . not that it was .
but was a tad clunky .i wasint sure that was a blade thing . my vfr is smoth as in the gears .
so you chould do a ebay search.

Cant see the seal you are referring to though (92049-1361), doesnt seem to be on that diagram

The double bearing on the output shaft isint avaible on mine either . but kinda worked out on the fureblade forum . its the single one . as thats right by the sprocket side.

Yes even if you chould which i really dobt i looked intp that.

Your crank shells fall out . as i got my cbr 900rr engine on the bench .
And just removed the split cases .i havent touched the crank and bearings.

Its not a big deal get the engine out if i can anyone can.

I did it by myself no jacks twin spare frames just lowered it to the floor.
Lifted bloody heavy but you can do it.

Just got bike back together this afternoon. Wheel bearings front and rear and sprocket carrier bearing and seals changed, old ones were VERY crunchy. New sprockets and chain, old chain was very stretched. Fixed a bunch of stuff with wiring, new fuel pump and filter, new pads, oil and filter, new plugs, flushed collant and fully cleaned out a horrendous thermostat housing, and a few other bits and pieces done.
Bike is much improved! In all respects. Smoooooth is one word.
BUT
The noise remains.
So, output shaft it is.
Ill tackle this in winter. Time to enjoy the bike. Shes never had so much TLC.https://uploads.tapatalk-cdn.com/201...46516b20a4.jpg
