Pig Posted July 26, 2008 Share Posted July 26, 2008 I took the car to whifbitz this morning so it can become quiet After beating my boss on his R reg fireblade 750 (in a straight line) I was sat at the traffic lights with the clutch down and for about 5 seconds i got a grinding noise. I lifted the clutch and it stopped, put it down again and it started. I then kept the clutch down and it stopped after about 4 seconds. The next set of lights i stopped and left the clutch up and the same noise happened. When it started i put my foot on the clutch and it stopped. Lifted the clutch up and after a couple of seconds it made the noise again and went away again after about 4 seconds. The gearbox has been slowly getting noisier with the clutch up but dont know if these 2 are related. Does anyone know of anywhere that can properly re-build a box? Also gaz, how much was your gearbox? If its not worth trying to rebuild i think i will just change the fluids.....again! And use it till it dies then get a new one.

JamieP Posted July 26, 2008 Share Posted July 26, 2008 Sorry to hear that mate, just to let you know there is no such thing as a 750 fireblade, the early ones are 900's so you did well;) Link to comment Share on other sites More sharing options...
Nic Posted July 26, 2008 Share Posted July 26, 2008 Sounds like it could be the clutch release bearing that has gone. Link to comment Share on other sites More sharing options...
Homer Posted July 26, 2008 Share Posted July 26, 2008 I'd be very surprised if it's the gearbox, sounds more like a clutch issue.# Edit - just seen Nic's post, that was the bit in my mind Link to comment Share on other sites More sharing options...

Amir khan Posted July 26, 2008 Share Posted July 26, 2008 I had a similar problem on my rover 220. I think that was the thrust bearing, sold the car before getting it sorted Link to comment Share on other sites More sharing options...

MrRalphMan Posted July 26, 2008 Share Posted July 26, 2008 I would guess the release bearing too... Hopefully it is something as 'easy' as that Jon. Link to comment Share on other sites More sharing options...
Pig Posted July 26, 2008 Author Share Posted July 26, 2008 Sorry to hear that mate, just to let you know there is no such thing as a 750 fireblade, the early ones are 900's so you did well;) Oh, thats strange. Im sure he said it was a 750. I was suprised enough that i had done him on that as the best i have ever done is a 600 03 plate as it ran out of steam at 150. Hey ho, ill try to get a pic and vid next time. Sounds like it could be the clutch release bearing that has gone. I'd be very surprised if it's the gearbox, sounds more like a clutch issue.# Edit - just seen Nic's post, that was the bit in my mind couple of people i know have had what sounds like the same thing, turned out to be the flywheel bolts being loose i think. best of luck anyways john I would guess the release bearing too... Hopefully it is something as 'easy' as that Jon. Sounds like quite a few people agree on that point. I will keep my fingers crossed. Just gone into my garage and discovered 2 oil patches. One from below the engine and one a foot or so back. Im sure paul will be able to give it a good look over. Link to comment Share on other sites More sharing options...
