Motorcycle Valve Noise/Kawi Tick after Top End Rebuild

[@techten1012]

Its cam chain tensioner bro. My ninja 650 started making exact same noise on cold starts at 40k miles. Never performed any valve checks from day one. Just changed the timing chain tensioner with manual one from ebay and its all good. runs like a champ. Have almost 44k on it, daily commuter.

[@terrortoaster4987]

Late comment but I recently ran into the same issue, and for how common it is, it was damn near impossible to find a solution. Thank you

[@gassilva2185]

Sounds like the cam chain buddy.The Kawis are known to do that.lose the top bolt then the bottom until you HEAR 1 click..just one click and you should be good to goo..

[@pkdann64]

Gas Silva thanks. True that was what the problem was. I adjusted it that evening and the sound went away.

[@mojoriden]

horrible noise...goes for ride lol

[@Fordahord1]

that's what I've done on my cbf125, still does 50-60mph+ but shit noise

[@pas0003]

Same here!! Don't know how to fix it and the mechanic said it's all within spec :/ Thanks for sharing :)

[@pkdann64]

The automatic tensioner is supposed to click but if the sound bothers you, you could either replace it with a manual CCT or pull out a notch on the automatic CCT leg

[@GhostHunterWV]

I agree!

@@pkdann64 hey buddy , I have a 91 cbr600f2. My bike is making the exact same noise. What exactly did you do to fix it? Please help me I cleaned the carbs already( pain in the ass) but they are good to go. Now I have that exact same noise. Please!

BROTHER YOU ARE MY SAVOIR!!!!!!!

[@dbrhdwk1239]

Bad tentioner makes a noise like a crankshaft problem.

[@PruikkiRacing]

Thank you, i found this helpfull. Valvr adjustement done on a V2 250cc bike, 12,000 Kilometers, after valve adjustements it got even worse. This might be it, chain tensioner? Perhaps, but so fast?

[@handyandydmv]

not to sound stupid, but what do you mean that you took out the cam chain tensioner and " took of two notches"? i would like to know as I'm purchasing a non running motorcycle so that I can fix my self at my pace self teach myself about mechanics. Thank you.

[@pkdann64]

Andrew Ordonez The cam chain tensioner has a "leg" that extends out to push on the chain guide. The longer the leg, the more tension it keeps on the chain. The leg has grooves/notches so as you pull out it locks in the length. More like a ratchet. In my video I pulled out two notches meaning I extended the leg out to expose two more grooves on the leg and made it a bit longer. I hope it explains it. Thanks.

[@samwellington5419]

Think you could help me out? I ride a zx9r 1999 and I’m having the same problem and sounds exactly like mine does right now except I am losing power. I can get one good pull and then the whole system winds down without command and shuts off, it does this every time. I can start it back up and rev it just fine if i hold it at 3k then rev other wise if I rev at idle it delays and sputs and drops under idle then comes back up to idle. The other day while riding it got so bad it sounded like I was on 2 cylinders but that wasn’t the case. I have to rev up to 7k and launch just to get out of a standstill otherwise it would die if I let go of clutch and give normal gas. I’ve replaced just about everything other than things inside of the engine block. Got an idea??

[@pkdann64]

Sam Wellington I would start to check for exhaust leaks first, especially around the headers. Did you do that already?

[@samwellington5419]

pkdann I have not! Would I check the rings ?

[@pkdann64]

Sam Wellington check the area where the headers connect to the engine head

[@dangerously72]

Did you resolve your issue? Sounds like you aren't getting enough fuel perhaps..??

[@elviszaraksingh2221]

I did the same thing on my bike but I took 1 click and I still hear a little ticking, do you think i should give the cct one more click ,and how do I know if the cam chain is too tight

[@pkdann64]

It's hard to tell when it is too tight. I would do 1 click and ride it for a few days before going up again if the tick didn't stop. Too much tension will wear the chain out

[@robbenalfans5501]

Can the valve problems cause a outfunction of the spark plugs?

[@pkdann64]

Not that I am aware of. The spark plugs get their signal from the timing system which in turn is governed by the ECU. However, if the valves open/close at the wrong time, it will not sync with the firing sequence and result in a rough run at best. Worst is when the valve opening does not sync with the piston movement. In that case your piston with hit the valves and result in a catastrophic engine failure.

[@robbenalfans5501]

@@pkdann64 yes but the spark i dont think will go out of function because of the valve,maybe is the fould of CDI packet or of the pulse

@pkdann hey buddy , I have a 91 cbr600f2. My bike is making the exact same noise. What exactly did you do to fix it? Please help me I cleaned the carbs already( pain in the ass) but they are good to go. Now I have that exact same noise. Please! It makes the noise when the bike is warmed up not when it's cold. Any ideas

[@pkdann64]

Motogenix 99 when was the last time you adjusted the valves? Do you have any significant loss of power? Also it is possible that the tensioner is in the process of adjusting

[@boosthack7915]

@@pkdann64 I need a valve job for sure. Been working on the bike for like a year. I just did the carbs. They are working good. I'm also going to change the cct can chain tensioner. But I neeeeeed a valve job.

[@boosthack7915]

Not sure on the loss of power yet ordering a new back tire.

[@boosthack7915]

It is a 91 and I don't think anyone has shown it the love I want to know what I mean?

[@boosthack7915]

Also what exactly was your fix. What made it stop ? Like break it down for me please

[@jessefpv9217]

What was the fix man.

[@pkdann64]

I adjusted the cam chain tensioner and that fixed it.

[@anthonyrobinson7922]

Hey having the same problem with my 02 zx9 I changed the timing chain and tensioner and replaced the top end of the engine and still get the rattle.. smh is there I'm doing something wrong??

[@pkdann64]

Anthony Robinson I would try to play with the the tension on the timing chain. It might be too loose. Caution, it shouldn’t be too tight either

[@anthonyrobinson7922]

@@pkdann64 I believe it's to tight ... but thanks

[@padeyjenteraretro2252]

sir... do you know why does my zx6r 97 rev a bit diff than before changing cylinder and the head...when i rev it.. i didnt rev well..sound a little brr brrr.... not vroom vroom as before... and also steam still coming out from cranckcase breather with pressure... ill upload the video ..i hope u can give me suggestion...tq

[@pkdann64]

padey jenteraretro it will be good to check if you have any air leak around the exhaust manifold. Do you have good compression in the cylinders and did you check your valve clearance? If you could upload a video, that would be good.

[@padeyjenteraretro2252]

pkdann ive done the valve clearance too.

[@pkdann64]

padey jenteraretro what about your cam chain tensioner? Is it loose?

[@padeyjenteraretro2252]

the cam tensioner is okay. ive check it... chek out my video... already upload it...

Was it a rod bearing? Is the engine still running?

[@pkdann64]

It was actually the cam chain that was a tad loose. After adjusting the tensioner, the tick went away

[@japfourme381]

pkdann Hi watched your vid with great interest, had the problem on me zxr400. I checked out the valve clearances which a couple needed doing. sorted that put it all back together started her up same problem! made a manual trensioner and fitted it, better but still a slight rattle cum tapping. something told me to check me exhaust studs. tightened all those up & voila sorted!! robin
