Just 2 days ago, I acquired a 2004 Fazer 600 fuel injected. 

Now I am very happy with the bike, but there is a massive flat spot between 6k to 8k rpm. 

Could someone please possibly point me in the right direction on where to start with this. 

I went into the diagnostic mode yesterday and Cylinders 1&4, were both set at -25 and cylinders 2&3 were set at -8. 
Could this be causing it ? 

Kind Regards

Is anyone aware of the process of ensuring the correct spacer size is obtained? 

In addition the fork oil is to be replaced. Do I use the specified 467ml of oil?

All advice and guidance is gratefully received.

For anyone interested the spring kit is code FRSP-S3732095 and the springs are 36.7x34.5x315 and 0.95kg]]>

OK, so did some town and country side riding last night, mainly to test the lights!  OMG, mission accomplished, I can see the road!  LOADS better than the FZS - Anyway....

I now see what B1kerDude meant about the clutch.  It's almost as though it's not releasing, slipping (not sure if that is right).  But it's like it's delayed, especially when in first.  Get to the bite (closer to the handlebars now I've adjusted it, nice) and it doesn't "engage" for a split second, and then does, causing a not so smooth pull away.

B1kerdude may well be right about the cable sticking, let's hope so, easy fix for my bike shop, hopefully.  Hydraulic etc sounds lovely, but funds need to be spent wisely, and not all at once :-)]]>

The bike shop were lovely, recommend them.  Waltham Cross Motorcycles.  Even gave me a free Yamaha T-Shirt and stuck in some more fuel to ensure I got home without needing to stop (nice touch).

Bike was comfortable, and got me home.  Pulled well, didn't thrash it, enjoyed the ride, except for:

Wind noise - so loud - see other post.

and, Ahhhhhh, the 6000 rev buzz.  It's still there!  NOOOOOOOOOO  was so looking forward to have a hand that doesn't get all pins and needles through vibrations.  Perhaps it's me.  The left is always fine.  But I was still having to shake the hand or waggle fingers every 10 mins or so :-(  Damn it!!

other than that, seems to whine a lot when you come off the throttle.  Normal?  Do they have a fair bit of gearbox whine?  Not a problem, just a noise I've not had when riding before.

As B1kerdude said, clutch was a bit bitey, but I adjusted it a little and brought the biting point closer to the handlebars - much better (more where I'm used to the biting point being).

I already feel so much more confident in corners.  I'm not a quick rider, but I felt more confident in how the bike handled bumps and didn't put the fear in me if I hit a bump mid corner.:-)  WIN!!!!

Found out the bike has an alarm - oh no - I've only ever heard alarms are a ball ache, draining batteries.  - Hope mine is OK.

Gonna pop out and try the lights this evening - hoping I can actually see the road ahead for a change.]]>

OMG, the wind noise on the motorway.  Unless I sit uncomfortably bolt upright, the wind comes off the front screen straight into my helmet.  It used to be into my chest on the FZS.  It was so loud, and I already wear ear plugs.

I see a taller touring screen our double bubble seem to be the fix.  I'm not fussed on a taller screen, it's already quite tall.  So what are people's thoughts on fixing this?

Cheers

Nowhere on the internet was I able to find back side of speedo (motherboard) with wires in exact places, so if anyone has picture of their own, or can help in any way that would be very welcome

I can provide pictures if needed.

I don't ride much in winter but a couple of months ago I rode into the city centre probably early February. While riding slowly in heavy traffic around the streets, my bike just died. Dash went blank and restart attempts just resulted in useless clicking sound. I had it recovered and checked. They said it was just an old battery and changed it and checked everything. Does that sound right ? I though once you have a running engine it should be a self sustaining system.


Anyhow, two days ago I went to ride into work. Again zero electric power and totally blank dash. I charged the battery overnight for 12 hours and in the morning it showed "Charged and maintaining" on the charger and the bike started (I didn't ride anywhere). Now this morning I went for a ride along the coast and after about 5 miles, same thing again. Down shifted to 2nd and slowed to let an oncoming car pass at which point bike again died. I had enough battery to attempt a few restarts but not enough to get going again, managed a few rotations and then useless clicking again. I have left it there while I decide what to do. Go back with another new battery, or have it recovered some place else maybe..

Admin, thanks for adding me.

I'm new to 600cc bikes and recently acquired a 2008 FZ6 S2 model from an auction. Unfortunately, the wires near the immobilizer and ignition were cut due to hot wiring. I successfully soldered the wires back together, but upon turning the key, nothing happened. The small clock on the dash appears when I press a button, indicating power is reaching the dash.

I've checked and replaced the indicators fuse, ensured all other fuses are not blown, inspected the battery, which reads 12.4v without any voltage fluctuations when key turned ON.

I have checked the continuity from the battery and everything seems fine

I visited a nearby motorcycle dealership where I was informed about the possibility of the ECU being locked, which blew my mind. Seems like £££££

Is there a solution that doesn't involve replacing the entire ignition system with an immobilizer?

Could someone kindly guide me in the right direction to bring this bike back to life?
