    Chirp on deceleration?

    Need a little help fro you all. My rex developed a chirp like a bird when letting off the throttle and decelerating and it also sometimes occurs on clutch disengagement. 25k miles, all stock 02 zrx1200. Any advice greatly appreciated.

    You didn't mention where the noise is coming from but I assume it's the drive section. Have you checked your chain for looseness? Take a look at your wheel bearings, if possible get it on a stand and wiggle it for play.

    Check the swingarm pivot bolt and the eccentrics, axles pinch bolts, brake caliper mount bolt, etc

    I'd check chain for tension and lubrication first, especially if the eccentrics have been flipped

    Ill try to get it on the stand this week and adjust the chain. Canít tell where it is coming from but happens every time I release throttle when driving. No noise standing still just running through rpm range. Thanks for the help, keep the ideas coming.

    Re: Chirp on deceleration?

    Have you already addressed the starter chain tensioner issue (i.e. installed KWICK's tensioner fix)?

    If not, look through your oil filler hole and see if you have any marks on your clutch cover plate. Below is a fairly extreme example of what you're looking for.

    I'm thinking that chirp might be the tensioner "pinging" off the cover plate when you chop the throttle.

    Some guys have had the removable frame link get loose on the right side. The frame will flex if the bolts are loose.

    Somethings bolted, not quite tight enough, will make noise as they move against each other. There is often red powder around the point moving if they are steel parts.

    Good luck.

    Re: Chirp on deceleration?

    one other remote possibility is you have your chain too tight or it is binding due to lack of lubrication
    There is an outside chance the chain is binding and it causes to the tire to resist spinning when there is no power to it. When you adjust our chain have a look for tight links.
    Unlikely I know but have seen it in other bikes
    and yes they were poorly maintained which I suspect yours is not

    Is the cush drive bushing dry? The cush drive will rotate a bit in the wheel with throttle manipulation, if it's dry it could squeeeek.

    The chirping on mine was clutch lever, some graphite spray fixed that - although I assume you have ruled it out.

    Re: Chirp on deceleration?

    Yep ruled that one out. Its most prominent when letting off the throttle from 1/3 or more throttle. I just pulled and lubed the clutch handle a few weeks ago cause it was getting sticky and lubed the chain. Been too busy with work to get it up on the stand but hopefully soon and Ill report what I find. Keep the ideas coming, they are all pretty good so far.

    Re: Chirp on deceleration?

    Little bit of chew on the basket so iím guessing the tensioner is the issue so Ill het a hold of kwick and order one. As long as Iím pulling it apart Iím thinking of doing the clutch. Its got 23k and I just commute on it but I have noticed the feel getting a bit different but donít get on it enough here on the island to notice any slip. What does everyone think...do the clutch and or what else should I do while I am in there? Thanks as always.

    Ill just pull them and check the measurements while I have it apart. What are the correct specs?

    Measurement tells you nothing.

    As the cork gets out it absorbs oil and actually gets thicker.

    Does it slip?
    Is it grabby?
    If not, do t worry about it.

    Rebuild the slave cylinder with a Factory seal.

    Sounds good, what should I look for other than feel. Burning or warping?

    Re: Chirp on deceleration?

    At 23k you likely won't find anything of concern, unless the previous owner drag raced the crap out of it.

    Fresh clutch fluid and a slave cylinder rebuild should restore feel. If you just want to spend money, buy a braided stainless clutch line to replace the old rubber line if you still have that on the bike.

    Re: Chirp on deceleration?

    "Warning, I will use "normal" or it's tenses, more than normal in this post, for clarity"

    The "normal" tensioner issue, noise or damage only occurs during engine cranking, it would not "normally" happen while bike is running and/or driving, or clutch operation/disengament, unless something is really off, not jumping to conclusions, but I would advise a complete clutch area/parts inspection, including removing basket and checking damper, etc. Like mentioned before a slave cylinder rebuild may be due, it lives in a fairly harsh place and are prone to corrosion, IAC just based on age of bike all this stuff and more could be due, winter coming so there's time.

    Not "normal" for these bikes clutch and components to fail, but your problem description is not "normal". Under "normal" riding/operating conditions the clutch should last well over 50k+ IMO.

    Re: Chirp on deceleration?

    It's not the clutch or starter\alternator chain tensioner....

    Do rebuild the clutch master and slave as well as replace the old rubber line to get the feel back. How old are the brakes?

    Stock exhaust header?
    If so, the baffle weld(s) can crack internally and make a racket.

    Also, the alternator:

    Re: Chirp on deceleration?

    Environmental is complicated issue, move every year or two and have been in NJ, FL, RI, NM, CA and RI again with the bike. Brakes are about 2k old and calipers weíre done at same time. All stock. Done tons of searching on the site before I made the initial post but there was nothing like what I was describing. Once the parts get here Iíll look around in there and see what I can find. Iíll pull all the plates to examine them. I do commute a lot so on and off the clutch a lot. Last time I had it serviced at the dealer they mentioned there was some clutch slip but I have never noticed it. As I said it like a bird single chirp when I chop the throttle, nothing on acceleration unless I just canít hear it and occasionally on clutch release at low rpm. Not a rattle or repetitive noise just once per my appropriate actions....chirp.

    Re: Chirp on deceleration?

    Mileage has next to nothing to do with brake and clutch hydraulic system condition.

    Maybe the throttle tube needs cleaning. Do not lube it, just becomes grinding compound.

    Re: Chirp on deceleration?

    Ill check the tube but only does it when moving, nothing in neutral while stationary and rolling at same speeds, only does it when in gear. Basically when the engine is slowing the bike down, which is why I was starting with drive chain and drivetrain. The chain seems fine and is well maintained, nice and free and properly adjusted. And as mentioned it is a single chirp and does not happen till I chop the throttle again. Im also going to check all the carb and airbox boots/connections just incase its an air issue. Thanks again for all the ideas and help.

    Did you pull the rear wheel and check the cush drive bushing? And rubbers? And there are 2 wheel bearings and a cush drive bearing.... That's the rest of the driveline...
