***VIBRATION HONDA CAMPAIGN***

[Stealth]

I have posted about this else where... but here it is;

Scott Manning, Queensland Australia.

2004 model... no mods... currently 2500ks

Its all though out the rev range now It's buzzing in the seat, pegs (right particularly), tank, and bars! It is less obvious at low revs, building to 4000prm, then basicly stays the same through to redline, except for 500prm either side of 7000prm where there is nothing. I first noticed it at 1000kms, and it's been getting worse ever since. It appears to be worse when the motor is cool (60 - 80deg C). Dealer has checked the throttle bodies, CCT, and balance shafts but there was no effect. There also appears to be some lumpyness in the motor but I don't know if that is relevant.

The vibes are everywhere...seat/tank/bars/ pegs (right peg mostly) and seriously detract from my enjoyment of the ride. My hands tingle after I dismount, after a couple of hours in the saddle.

I am seriously pissed about this...thanks for trying to help :B

sorry it's taken me so long to post a suggestion to the last post Stealth, I haven't visited this thread for ages.

My XX had a lumpy tickover, turned out to be throttle bodies. Settng them up sorted it, although re-mapping my Power Commander helped too. Hope that's some use.

I'm just about to put my '99 Bird up for sale. It's done 18000 miles and is smooth as silk, always has been right from new.
Is this just a problem with newer Birds or was I just lucky with my first one ?

I have just got DPBxx's old 99 bird and although I have only had her a couple of days, as someone else said smooth as a mill pond. when I picked her up I had a 40+ mile motorway ride home at anywhere between 60-80+ mph and not a ripple

Iwas getting "numb" fingers in my right hand ,got a mate at work to knock up some bar end weights 2mm bigger in diameter and 5mm longer in lenth made out of phosphor bronze [heavy] ,result = magic carpet like ride

OK peeps I'm getting a very annoying vibration at about 3500rpm and over.

My bike was as smooth as silk right up to 250k/hr now i get vibration at 110k/hr. OK, what I have changed on my bike since it started is 4 rear shock spacers (6MM total) and tightened drive chain to the specified tension (25-35mm centre chain slack) and waxed it.

Now what I distinctly noticed before I tightened the drive chain was that the chain slider was about 3MM out on the left side when compared to the right side. When I tightened it, I made it so they were both even (like they're supposed to be) but now the bike has an annoying vibration.

Dunno whether it's the four spacers under the rear shock or the drive chain adjustment should actually be changed, so it's 3MM out of alignment like it was when the bike ran smooth. Will experiment with it today and let you know tonight.

Any advice will be appreciated. Cheers.

Those chain adjusters are notoriously inaccurate. I always used the old string and time method. If you once get it set properly you will see just how far out the adjusters are. The important point to remember when measuring from the string to the front rim is not what the measurement is but that all four are the same ie: front/left, rear/left, front/right, rear/right of front rim to string.

If this is chinese to you pm me and I will send you a step by step instruction.

Secondly, but no less important, the chain needs to be checked off the stand when you have 6mm on the shock. 6mm causes the chain to be well slack when the Bird is on it's centre stand so you can easily set it too tight if it's adjusted as per the manual. I kept mine slightly slack, no vibes at all.

Hey dpbxx,

For some reason I can't send you a PM but it would be good if you could send the step by step instruction to my email account "pakky48 AT hotmail.com"

Someone on another forum said it could be the CCT and the only way to tell is to put the bike on the center stand and rev it to see if the vibes appear or not. Only problem is I don't know what the CCT is or what the initials stand for. If someone could explain it would be great

Cheers.

chain tension should be checked on the side stand only. 30mm play is about right.

the adusting marks are shit, ignore them. measure centre of axle to somewhere on the frame that is on both sides, repeat other side, get measurement the same.

 

[Supabird1100]

Only problem is I don't know what the CCT is or what the initials stand for. If someone could explain it would be great

CCT = Cam Chain Tensioner. Small, spring loaded device on the engine block that takes up the play in the cam chain.

If it's gone....you would hear it. Sounds like a bag of spanners rattling around as well as causing vibration.

Hope this helps :beer:

I can second that, because I bought his bike and it is still as smooth as silk, and the chain is slightly slack.
Cheers DPB.....
hows them there hogs???

u want vibes i have vibes

upto and includeing 100mph no problem smooth as silk
100-120 some times not always so much vibes the bike can't get past 120
other times bike flyers to 160 odd smooth as silk?


i am currently going through this with jaws because it also seems to misfire now and again not not regular


but the good news is i have fixed (with jaws's help)the charging problem so we have electric back again
just the vibe and the misfire/backfire to sort out

what have i bought to try n fix the prob lmfao (not funny any more)
new tyres/2*recfityers/ new chain (gold)/new sprockets /new generator/ new head bearing

am i pissed off well yes i bloody well am:bang: :bang: :bang: :bang:

 

[poshdave]

buggerrr

oh yeah and a fookkin oil leak

 

[solorider]

rode minw to wales today and found it vibey uo to 5000rpm,just after that the bike was smooth as a babys bum,which was at 95mph i have a 1997 carb model which is a low mileage bog standard model(15k miles)

 

[CbrDavE]

Only happens at higher engine speeds eh!

You have checked the air filter have'nt you?
Service intervals for air filter should be more like 8000 miles.

The blackbird uses a ram effect system that collects more sh1t than other bikes coz the intakes point forwards.

Just a thought.

 

[solorider]

my bike was serviced a couple of months ago and as far as i can tell the bike wasnt rode in the wet,plus my bike does not have the ram air system(carb model) so the air filter cant affect some models.but my bike gets smoother if you rev it over 5k rpm

Pity I am so far from Tony1100, will somebody go there a slap him . Has he got no pride, going from a bird to a fazer uke: . We enjoy our bike, not just looking for transport. Even with the vibes, etc. nothing comes near a bird. man8um Tony all I can say to you :f :wank: 8l1nd you need :h

 

[solorider]

changed the cct and no difference,my next job is to check the balance shaft tension

 

[rearset]

Engine vibration just started...

So, I'm tooling down the M56 at spot on 70 MPH doing the m/way section of my advanced training with South Cheshire Advanced Motorcyclists (S.C.A.M. yes, I know!!) and I realise my right hand has gone numb. I thought it was 'cos I'd been on the bike so long and ignored it. Ever since that time I've been aware of increased vibration kicking in around 3 -3,500 r.p.m. in any gear. I rode back from the office tonight, doing the 30 miles in a leisurely 40 minutes and my hand and gone numb and my feet were tingling. Spinning the engine up while stationary on the drive the vibes kick in at the same point and you can feel it through the tank as well, so no doubt my nuts are gonna get it. I'm seriously pi??ed as it was soooo smooth until a week ago.
I've been up and down this and other forums and am looking for a kind of checklist to work from in order to find a cure. What's the latest thoughts on this problem? I don't think I'll be able to do my test on this the way it is as it's too distracting. The next mod it might be getting is a for sale sign on the windscreen.
Oh, and my sh?te Nolan helmet has got a crack in it. It's just going to be one of those weeks, isn't it?
Any help gratefully accepted.

Rearset..........

there are lots of things you need to check before finally accpeting you have a vibrating bike!!!!!

CCT, balance shafts, tyres, chain.........................just but 'vibration' into the search part of the site and you will find lots of things.

We now have another blackbird, but it still vibrates!!!! We have found that some vibration was caused by the kappa rack, with an SW motech its slightly better. Full luggage makes it worse and also having noisy exhausts can do it through the pillion pegs.

Thats 3 we have had now with varying levels of vibration. :dunno:
