Hey guys,

I know that some of you are grease monkeys so maybe you can help me out with some of the issues i have with my bike.

For unknown reason when i start my bike in the morning when it is cold, it makes this knocking noise. It is like tapping, thats why i was thinking maybe it is valve clearance but that knocking stops when the engine warms up.
It might have started after oil replacement, however, i double checked it and there is right amount of oil, and it wasn't cheap oil either.

Now the bike has only done 16k, (i got told it might be pistons, but i dont think pistons would die after 16k of nice riding :baby:)

Another issue that i have (it might not be an issue), i got told that my bike sounds like carbs aren't balanced. I have never done carb balancing, i have cleaned carbs before, i saw few tutorials on how to make carb balancing tool with piece of transparent tubing and piece of plank, but how accurate that would be? Does anyone have any feedback on that?

:headbang:

cheers

Sounds like it could be a cam chain. I had a similar problem on my Zeal and that was the cam chain.

Was it only when the bike was cold? What did u end up doing? I never done anything with cam chain. Do you have to replace it or adjust it?

It rattles/knocks, i would say it sounds a bit like desel engine when it is cold. When it warms up it is way better.

The knock was worse when the bike was cold. The problem was cured by replacing the cam chain. The mileage on my bike was similar to yours.

Yeah sounds quite plausable. Is it a manual cam chain tensioner or automatic? If it's manual you could try tweaking it a little and see if the noise goes away...

That is a very good question.... Hitcher have you got any manuals for zeal? Or maybe you remember if it was automatic or manual. If it is manual, i can get my flatmate to adjust it for me and we will see if it does anything.

Sorry, no Zeal manuals. Ring up your closest Yamaha workshop and ask them.

I only managed to get owner manual, of some Russian website, no service manuals in english (jap import). I'll keep on digging.

If anyone wants owner's manual for zeal please pm me.

Jeaves (http://www.kiwibiker.co.nz/forums/member.php?u=7408) told me once he has a workshop manual, you could ask him to see if you could borrow it (if he still has it).

Yep still have it. Auto tensioner by the way

I'd be suprised to see bikes this day and age with manual cam chain tensioners.
The ticking seems indicative of a worn tensioner, so that it the first thing i would try, although I am far from a reliable source, the knocking may well be a result of the tensioner, but i have no idea.

inline four, right?

not having done it myself, but having had it done before, i'd be keen to give you a hand

ask at a shop for the chain & price, and see if you can view the exploded parts diagram, they should be happy to print it out for you if it means a sale.

speculation:
if it's got a master link that we don't have to rivet with a special tool, we can remove the rocker cover, open the old chain, clip the new chain to it, draw it through and join back to itself. easy job, few beers should do it.

if it's an endless chain, which would seem "safer" for the application where a fuckup means a new engine, we'll likely have to do some minor to complete disassembly of the motor to change it, depending on where it sits, ie between cylinders or just behind flywheel. a lot of tools, a lot of time, A LOT of beers.

any more experienced mechanics know more about this bike? i'm guessing it's a case of a special rivet tool; reliable and easy.
any known ways to emulate the tool? hammer and hole punch?:D

what year model is that zeal?

I did the cam chain in my zeal a long time ago. I posted a thread (or two) about it:
http://www.kiwibiker.co.nz/forums/showthread.php?t=21195
http://www.kiwibiker.co.nz/forums/showthread.php?t=16549

There's some photos that might be useful. Please don't post in the threads though, they're so old and I'd rather they weren't dredged back up.

the chain I got to replace it was a Regina morse chain part number: 82RH2010M 112 links.
http://www.reginachain.it/eng/products/production_range/scheda_morse.shtml

I'd be surprised if the chain needed replacing after just 16,000km though. I'm not even sure my one needed replacing at ~70,000km.
Maybe the cam chain tensioner is sticking a bit?

I do remember my zeal used to make a knocking noise at idle. I think it went away when you pulled the clutch in. I can't remember if it was just when cold or not.
It could be that the knocking noise is normal. Maybe get someone with experience to listen to it.

It is 1991 yamaha zeal.

It would be much easier if i could lay my hands on service manual ;)
(hint: Jeaves). I went to mechanic this week and they had a listen to my bike and they said that it is either cam chain or tensioner or both.

alas it is 170 kilobytes too large to attach here....

and I don't think KB approves of .zip archives.

kinda silly being able to post 2MB .doc files but only 1MB .pdf files....

I might make a torrent of it later seeing as we can post those.

nothing wrong with leaving my sever seeding several hundred MB of motorcycle manuals for those looking on KB

though realistically i probably cbf - all my manuals are on my dead hdd which is yet to get back from seagate
