the 750s sound very good  ...if that mileage is correct the pipes will probs be origanal honda,very rare , expensive and look great  [size=78%]......iam on my way with trailer and a wad of cash [/size] [size=78%] would look great in the garage next to my 400/4 [/size] :rollin :rollin

[CRH]

well i wouldn,t bother getting your trailer out red?....never seen so much rust on a bike in me life!! dont know who this fella trying to kid??...yes engine ran has he said very sweet!!...did not mention the amount of blue smoke it kicks out though?....he did say though it had been garaged all its life,and yes" he may have been telling the truth?...just wondering though?..how long the garage sat without a roof :rolleyes .....he then asked me for a grand plus my thou :eek ...told him to go away in large jerky movements! ...without costing it out fully?..it needs a full restoration ,even the frames starting to rot through under the seat!!...you would end up out of pocket on this one? and the one he,s throwing in for spares is no better?..said the engine was a good runner?..couldnt even turn it over!!....and the best yet is the commando? :rolleyes ....i would be ashamed to even ride it!! :eek ...biggest load a crap ive ever seen,..and get this? he wants 4k for it, makes mine worth about 20k going on that!! :lol ...so think ile stick with the thou f now and get it finished over winter!! how you getting on with the 6.?

[red98]

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 
next job on the 600 is too by-pass the fuel pump and see what happens,after that maybe the jets  :rolleyes

[red98]

not posted on this thread for a while :\ ....been putting a new roof on my garage,weather permitting should finish it the weekend ,small job to do on swmbo`s car and then its back to the stutter 

[CRH]

hi red long time no hear?...well hurry up and get it sorted!!...then you can help me sort mine out :'( ...yes youve guessed right?...i got a fkn stutter now :'( ...wont rev above 6k...not done owt to it so not sure yet what could be doing it :rolleyes ....not used it for a few wks, its got fresh petrol etc so can rule that out?..starts first touch of button,..no miss fires revs nice and idles nice and smooth :rolleyes ....but try and get it to rev above 6k?????..not a chance in hell!!!!!....its like hitting a rev limiter!! :\

[clayt74]

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

[CRH]

hi, clayt...yes thanks for that ile give it a chk over this wkend and check all that out?....the bikes been kept nice and dry though in me garage!..like i said not been used for a few wks?..just hope its not picked up the...red stutttttering virus" :\ ....am hoping its just my plugs?..still got originals in ,but only done 6700 miles from new !!..

[red98]

any news on your stutter CRH 

[darrsi]

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.
keep the posts coming in

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    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.....
