hi crh ,trailer now back in the garage :( ...thats a bit disapointing and a bit cheeky asking for your bike and a grand  :eek ...a full restoration like that will always cost more than the bikes worth  :rolleyes  you done the best thing,just walk away  ;)
 ive just reassembled the 600 and pushed too one corner of the garage as i need to fit a new roof  :rolleyes  hope to make a start this weekend weather permitting :rolleyes  nice clean and tidy garage at moment  :D
 next job on the 600 is too by-pass the fuel pump and see what happens,after that maybe the jets  :rolleyes

hi CRH, i had a very similar problem last week, but mine stuttered at anything above 4k.
it was actually dropping a cylinder.
the prob with mine i think was 3 issues,
the well for the plug caps had wet leaves that had blown in (due to being parked up under a tree)
i also found a HT lead was a bit loose in the cap on cylinder no2
and when i took the plugs out the gaps were way too wide, cleaned and closed the gaps and it now runs better than it has in ages

Just think, in a thousand years time people will be unearthing age old versions of the bible, and even more remote and in depth, Red98's version of how to fix a stutter on a Fazer (just kidding)  :lol

Hi everyone,

I've been reading this thread and my fazer has similar problems. I've not got the flat spot, but around 8000 - 9000rpm the bike stutters before picking up again.  This is when I crack the throttle open quickly from, say 7000rpm. If I roll on slowly, the stutter is still there but less noticeable. If I accelerate from say 2000 - 10000 rpm, the acceleration is normal, no stutter.

This happened after I changed the air filter and (foolishly) added a small amount of Redex carb cleaner.

Before this the bike was running a bit rich, but other than that fine.

So any advice where to start looking would be welcome.

I can do a few basic maintenance tasks, but not things like stripping carbs.

I did think about putting the old air filter back in to see if that made a difference.

Cheers!

yes.....try putting the old filter back in and see what happens.....iam going to look at my fuel pump next,by-passing the pump and filter with a piece of tubing and using isaac`s laws ,see if it makes any difference  ;) [size=78%] [/size]

hi all
been reading this for a while, will be joining in shortly. just got a fazer and spent 510 getting it rite and it has got one bad cough!! had it before it got once over, was gone for 60 miles and now back with vengeance  feel mine must be a fuel problem as mates mate didnt drop the fuel and clean the pipes when carbs got balanced and cleaned. just terrible under 3500 and runs like dream afterwards. going to get go pro on and post link to video this weekend.

I will try the filter back in at the weekend and let you know how I get on.


I just had a thought though. A friend checked the bike out for me a few weeks ago and commented that 1 cylinder was running hotter than the others (down pipe was noticeably hotter from startup). The other three cylinders were running a little rich(petrol smell) I will check the plugs at the weekend to to confirm this. Anyway a lean mixture would get even leaner with a new filter, so I wonder if one cylinder is too lean at high rpm and is causing the stuttering?


I assume a carb balance may be the simple answer as in the long term, I cant simply stick the old, clogged filter back in, to force the bike to run rich.


Does this sound plausible though??

ummmmmm .....not sure about that  ;) ......start by swaping the filter...i dont think thats the problem but once swaped you can forget about it  :) .....balancing the carbs is always a good thing  :D  do you know when it was last done ?  :)

I've owned the bike 3 and a bit years, and they've not been done in that time! Probably should have done them sooner. :\  Will get them done hopefully in the next week or so, have a friend with the kit needed.....

.....well, checked the plugs and ht leads, bit of wd40 applied. Left New air filter in place as I noticed the rubber cover over the airfilter casing had snagged over the air intake, possibly restricting the airflow. Assuming the engine needs a huge "gulp" of air when the throttle opens, this may have been an issue. Will test ride before putting old filter back in.


Bike fired up fine, needed a bit of choke, normally doesnt! Idling ok, just a tiny bit lumpy...


Will post back later!!

@cnw180, I had a complete carb overhaul done at PDQ, cleaned, balanced, etc, but when i went back there about 18 months later with a rough running problem between 2-300 revs they balanced the carbs again and said that they were quite a lot out.
I really noticed a difference when riding home, so i'd imagine that if you haven't had yours balanced in over 3 years that could be a place to start first!

fixed me stutter!! ;) ...very weak spark on number 3 plug?...so trimmed leads and replaced caps plus swapped plugs as i had a new set in stock!! and runs perfect again. :D ....what i did notice though was when i released the tank filler cap" there was a lot of suction on the cap?...chkd out the tank breather and it was blocked :rolleyes ...now cleared!!...

After 8 months this has been like a master class for the air / fuel system in the Fazer :P
