Help Guys!

Bike's just had new plugs and coils fitted today - was running so well (had been miss firing etc).
Then 12 miles on engine cuts out and engine warning light comes on. Does run but on 1/2 a cylinder not like 3 cylinders.   :eek

Error code 34 shown on screen - coil nr2 (was one of the ones replaced).

Is this correct? If so I'll drop the rad off and change the coil for one of the old ones.

Thank you for your help.


Need to be complete with wiring harness and not rotted out (like the ones I have!).

Many thanks

Fazer 1000/FZ1 corner / FZ1 Gen 2 - rear shock
« on: 29 November 2018, 08:33:45 pm »
Off to the tip at the weekend - just checking that the old shock of the Gen 2 can't be rebuilt? The spring on it is grey/silver while the 2nd hand replacement I put on the bike about 2 years ago is yellow and a bit harder.
Looking in manual I didn't see any spring rate/color charts - any ideas?

Many thanks

Fazer 1000/FZ1 corner / Oxy - acetylene kit - replacement
« on: 25 November 2018, 07:09:21 pm »
Need some more advice please:

For years I had a BOC ticket and porta pack oxy-acet with the usual stuff for cutting and welding etc then about 3 years ago the licence renewal came in at £400 or so and just not worth it as a nice to have in a DIY workshop and using it every two/four weeks or so.

Be good to have it back (but not at that £400+ price tag) for heating , welding and brazing - has anyone experience of the canister/aerosol fed oxy-acet or oxy propane (less hot but think ok) systems??

Many thanks


Fazer 1000/FZ1 corner / FZ1 Gen 2: handguards/muffs?
« on: 22 November 2018, 02:03:31 pm »

Need a bit of advice please: have fitted Oxford muffs before and while they do keep hands warm they collapse onto the levers at remotely high speeds. I've heated grips and prefer to ride with summer gloves hence the need for a bit more wind protection.

Any other options that fit the bike and work ok? - don't care what they look like!


Fazer 1000/FZ1 corner / Gen 2 - clutch actuation force, post nr 2
« on: 14 June 2017, 06:39:10 pm »
I've checked the new slippery cable that was fitted a month or so ago and it's all free - disconnected at the lever on the bars and it runs smoothly and easily.

Clutch force required to actuate is pretty high and, comparing to other FZ1s and R1s with a similar engine, it needs approx twice as much force to actuate. Think I'll wear out my two clutch fingers soon!

The clutch is original at 49,000 miles of mainly town commuting (also lots of clutch slipping as I'm really a 2T rider).

Before I tear it down any specific ideas to FZ1s  on what to look for other than the usual worn basket etc and possible solutions and products?

Any ideas would be much appreciated.
Thanks guys

Fazer 1000/FZ1 corner / Gen 2 clutch lever actuation force
« on: 25 May 2017, 01:36:12 pm »
Need some views/advice please:
My Gen 2 has done 48,000 miles commuting and the clutch cable was quite stretched, so bought what was described as a super slippery one from Wemoto. Eventually changed the cable after being a bit ditzy (think I was tired – see earlier post) and although the new cable was a lot smoother out of the bike compared to the new one the actuation on the lever is still reasonably stiff compared to say my mates ’04 R1.

Cable route seems ok etc as per the old one that came out.

Any ideas or solutions please – I tend to ride using 2 fingers for each lever and also slip the clutch as I’m also used to riding 2 strokes off road (ok these have hydraulic clutches)...
A bit lower force would be good to have and my finger joints might last a bit longer!

Hi Guys

Had a quick look at the cable this evening:
Lever end is now pulled through to under the tank
Clutch cable bracket at clutch actuator end is released but unable yet to get the locking nuts undone.

Once released it looks like the cable can then be drawn back and out of the LHS.....???

Any ideas please!!!
Many thanks

Needed to change the rear disc on the Gen 2 FZ1 and had been warned that it can be difficult to get the bolts undone.....

So soaked the threads in Plus Gas, froze the bolts (instead of warming the hub) to shrink them down, tapped them with large diameter pin punch to upset them and then tried to undo them...

2 undid ok, 2 T40 heads snapped off flush in the bolt heads and couldn't be removed, the other snapped off but did come out. What to do as the T40 heads are too hard to drill?

So welded M16 nuts to the bold heads and they undid fine with no damage to the hub (serious thermal shock helped). Not sure what else I could have done - may also work for the front discs as I've heard that the whole wheel gets thrown away if they can't get the bolts out.

The design of the bolt heads is wrong - the ratio of the T40 diameter to the bolt diameter means if the bolt is at all seized it's then very likely the T40 will fail - I used reasonably quality T40 heads...

Fazer 1000/FZ1 corner / FZ1 Rear Disc Replacement
« on: 22 February 2017, 07:29:45 pm »
Just had the tyres changed  and the shop reminded me that the rear disc at 45,000 miles is close to US ...(no no not Donald).

Looking on line think I'm going for a standard EBC disc at around £90 - the other makes I don't know about and have a few bad experiences on the KTMs with after market discs that wear out in a few miles.
Any thoughts?

The other issue is getting the old disc off as I understand that it's a 'mare - so plan is to warm the assembly up, at penetrating oil, leave, warm up again and then use impact driver on the heads. If they shear off then I'll have to drill out and retap.
Again any ideas would be really helpful.
Thanks guys


Fazer 1000/FZ1 corner / FZ1 Gen 2 missfire
« on: 02 February 2017, 08:13:58 pm »
Before Xmas I jet washed the bike and then stored it in a fairly humid shed until the new year  - result took several miles to run even normally..... It's a 2009 bike of some 46,000 miles and has always run well until now.
Now 5 weeks later of commuting I've an intermittent low speed misfire - more like a slow speed cough stall  I  used to get on my old 525 Katie.

So the plan is, having bought a spare coil, to test all the coils, dry, strip and clean the wiring above the engine (spraying GT85 here caused a misfire)and maybe spray it with electrical sealer. I'm hoping that the problem is caused by a coil breaking down. Does this make sense?

Before I take the bike apart is there anything else I need to be looking at?

Many thanks

Fazer 1000/FZ1 corner / FZ1 Gen 2 shock change
« on: 28 November 2016, 08:40:13 pm »
Blown the rear shock on the 2009 FZ1 - only used for commuting so at 43,000 miles seems quite low mileage but then the roads are pretty bumpy....

Anyway got a second hand one on ebay 11,000 miles (as new one £ lots) but not too sure how to undo the top bolt and what needs to be removed so that the bolt can withdraw about 50 mm on the rhs. Is it easier to loosen the subframe?
Removing the bottom brackets and dropping the shock looks ok if I can jack it up to get enough clearance or over the pit.

Any help gratefully received.

Many thanks


I need to change the clutch cable on my Gen 2 FZ1 – any tips on the best/easiest way? Am fitting a 'smooth' one from Wemoto....

Also my clutch plates are on the way out (I ride it like a two stroke and slip the clutch - bad habit I know hence the clutch cable change as it's overused) any tips on changing them

+ I’ve heard that the EBS plates are good value and also help soften the ‘clunk’ when going into 1st. Any thoughts/experience?

Many thanks

Fazer 1000/FZ1 corner / FZ1 gen 2 - ignition coil meter readings
« on: 28 July 2016, 06:01:29 pm »
can you help:
Need the metre ohm readings for the Gen 2 coils - I think I have an intermittent misfire and suspect one of the coils is on the way out.

So for the LV side - one range of readings for acceptable.

Ditto for the HV side.

Many thanks

Fazer 1000/FZ1 corner / FZ1 Gen 2 - Chinese radiator experience?
« on: 13 April 2016, 08:55:39 pm »
My 2009 FZ1 has had an on going radiator leak that I've tried to ignore - mainly caused by riding through the winter and rotting out the bottom of the matrix. I've bodged the leak with a 2 pack sealer and it's partially stopped the leak..... but now it's getting warmer I think the leak is going to spread.

I posted a question before on what to do and the answers are approx.:
Buy Yam original from UK
Buy Yam original from USA (better price and exchange rate)
Buy Chinese one from Ebay - £100. BUT has anyone fitted one yet? They all seem to come from the same manufacturers (just different sellers). Was thinking if it lasted a couple of years then it's fine? Does it fit ok including the fans etc?

Any thoughts - many thanks

Fazer 1000/FZ1 corner / FZ1 rear wheel bearings
« on: 02 February 2016, 06:27:24 am »
Checked rear wheel bearings - they're shot; that will be the third set in 35,000 miles and I've been pretty careful when fitting them (freeze new bearings and hot air gun on wheel etc). Think it's the pot holes and general bumps that catches the needle roller as don't have these probs even on the KTMs off road and they hit a lot of things!

Any ideas?
Many thanks :'(

Fazer 1000/FZ1 corner / FZ1 2009 - spark plug change
« on: 01 February 2016, 01:40:15 pm »
Need to do a full service this weekend (but not valves...) and never changed the plugs before (garidge did it last time) - any tips please to avoid wasting too much time?

Many thanks

Fazer 1000/FZ1 corner / Fazer 1 2009 radiator leak - options
« on: 18 January 2016, 07:25:48 pm »
Just got in from the daily commute (traffic v bad in SE London) to find I've holed my rad - not sure if it's corrosion or a stone but hard to identify exactly what the cause is.

New one from Yam looks like around £370, any ideas on what my options are :eek

Any ideas would be v helpful!


Fazer 1000/FZ1 corner / FZ1 2009 - very slow tick over when cold
« on: 19 November 2015, 06:15:56 pm »
This morning 8 degs C and the bike wouldn't start with the throttle on the stop which is what it normally does. So to get it going it needed a bit of throttle and then TLC until it was warm enough to tick over without any assistance. It's been running slower and slower on the cold start over the last couple of weeks.
Once it's warmed up a little it's fine and the hot tickover isn't a problem.

The bike is used for commuting and done about 34,000; each run is 25 miles or so. It's serviced on time and apart from this problem has never missed a beat to date:)

Any ideas? Many thanks :)

Fazer 1000/FZ1 corner / Heated grips for FZ1 - recommendations???
« on: 12 November 2013, 06:15:41 pm »
Just realised it is going to get colder and am thinking of fitting heated grips this winter on my FZ1.
What do you suggest? Reliable and effective seem highish priorities....
Normally I've used Oxford muffs that do a reasonable job of keeping my hands warm but thought this year I'd try KTM enduro (got old pair in shed) wrap round guards and heated grips.
For the last 10 winters I've been wearing a 60 W heated waistcoat/jacket that is just great for keeping the core warm and allowing warm blood to flow out to the limbs rather than them getting cold and shutting down.
Many thanks

Fazer 1000/FZ1 corner / FZ1 (2009) rear suspension linkage bearings
« on: 23 September 2013, 09:15:43 pm »
I've got quite a bit of movement in the rear linkages (ie about 6mm when lifting the rear wheel...only done 17,00 miles - must be the poor roads and pavements....okay I should have stripped and greased them on a bit more often).
Marc at Marksman (v helpful and supplied the bearings for the rear wheel £44 v £120 from Yam) has been able to identify the bearings in the Al linkage/dog arm but has anyone any idea what the other ones are:
The needle bearing under the swing arm
The bearing in the lower end of the shock (rose joint?)
Also any tips on how to remove the one under the SA? Looks like the shock top bolt is a 'mare to remove.....
Many thx
Tues24 Sept - think all sorted, local Yam dealer is supplying bits that I can't measure until it's all apart. Think fitting the bearing under the swing arm will need to be put in the freezer before v careful pressing in. Not sure about the shock bearing - the micro fiche shows just a sleeve...
Good news is that the Yam dealer thought at worse the current movement would get an advisory, so should be ok even just doing the linkages.
