Noise from an '88
So I just got a 88 1000,great bike,but it's been about 15 years since I've had a chain drive bike.Chain was replaced by the previous owner,but not the sprockets.Seems to me like alot of noise from down in the primary area of the chain (small sprocket).Just me being **** and used to shaft drive?

Howdy WC,
I think typically chains and sprockets are all supposed to be changed together at the same time as they all wear together. Putting a new chain on old sprockets will wear the chain down a lot faster at minimum. I think you can get away with just changing the chain if you change it immediately as it hits the outer spec.
How do the teeth on your sprockets look? Are they hooked at all? Are the "valleys" between the teeth clapped out looking at all?

'Kay...Put new plugs in,valve cover gasketnot seated right on cyl. 3 and 4,weeping a little oil.With the bodywork off,sounds like the noise is comeing from those 2 cyls. but it's more off a chain noise than a valve tap.Waiting on local dealer for a new gasket before taking off valve cover.How long can you expect to get out of the timing chain in one of these,and is there anyway to change it without spliting the cace?The ol' girl has 47,000 kms. on her now,noise doesn't get louder with revs,and can't see any loss of performance from her.Oh yeah,one other thing.How do you guys ride one of these road rockets and keep a liscense?

Congrat's on the new ride there WC. Sounds like a thrashed chain primarily. Since you are not the original owner I'd recommend you spring for a new front and rear sprocket.
Sprockets : Smaller fronts i.e. <17 tooth will make more of a ratcheting noise period
> 17 will be much smoother quieter.
Rears pretty much all the same no matter what size but all exhibit a bit
of what I can describe as a whirring noise. Ya won't hear much of this
with your helmet on but might freak you out a bit if you've never heard
chain noise and driveline before with your helmet off.
Another essential is accurate wheel alignment and as a consequence chain
and sprocket alignment and CHAIN TENSION
I have a few threads on dicking about with Sprockets and ratio's with some good photo's. Got most of my sprockets and Chains from Sprocketcenter.com and have been very happy with their product and service. They have a gear ratio chart on there
as well a some good tips.
Good Luck with the new 88 I'm sure y'll get her squared away good.
Riding em is fun & easy around here, but you'd get tapped on the rear wheel for doing the limit (if you tried
).

47,000 If she has not had a cam chain or tensioner for a while , means she might be ready for one ..
No fixed rule really as to how long these parts last ...
Some guys have done them in as little as 5,000 , as for me,... mine have been in fore a long long time
, which om not divulging nor admitting too by the way..Lets just say that it is not totally uncommon to run these parts for tens of thousands before swapping them out !!
...and
Yes they can be done without splitting the cases ...
Type cam chain and tensioner into the Hurricane search and you will get a ton of great posts and info on this broadly discussed topic...
How do I ride mine without loosing my license .... well to be brief , I have had 15 motor cycle licenses , or should I say ov lost 14
over the years and the only reason my CBR has not cost me one more as yet, is because I have slowly learn to go fast , really fast everywhere so I cant see the buggers and I now also pray allot more regularly ...
I think actually I have just had a lucky streak for some years now
....going slow is an aquired skill , that I am still in the propcess of aquiring
Gawd , yer I know , I have a problem keeping a straight answer coming on this point , because , chit , I tend to speed at least a little bit everywhere ,and on open road , allot!!...
The only exception is in the built up low speed zones , where I do stay within lets say 10klm per hr of the limits set... which only get us a smack on the wrist...
I really do not know the answer to your question ...so I think I will STFU now..
