P-Diddy

Just had a couple pics to throw up. I'd say it took a while but this was the first time I've messed with a F4i and I had the service manual which makes it pretty hard to mess up.
Story: bought bike, got started, idled like normal bike. rev'd to 2.5k to 3k and heard a nasty rattle. not ticking. did some research, found out this exact description happened to someone else before and it was cam chain tensioner. talked to honda service, said it was a good place to start and it was common on the F4i. ordered the APE manual tensioner, read manual and followed steps for removal/installation. got everything back on today and started up, wondering if it would rattle? bike idled, rev'd like new.
here is a couple pics of the APE tensioner on the bike. Feel free to ask any questions, I'm by no means a mech. I will tell you what the manual says or from my experience. I'm out

glad to see you got it all set

that it is bro. one more question, i haven't tighten it since i got it in. there might me a hint of a quiet rattle right at the start of rev. did you tighten it until no sign of a rattle? (i know you said tight until no rattle, but i'm just being cautious ) thanks again for your help.

think the F4's have the same problem? mine rattles at 5grand and only at 5 grand and i never knew what it was? i always just said **** it, if it blows ill buy an f4i

Yeah, Mine rattles at 5k - 5.5k. It sucks, how much did you spend to do that? I gotta go so just pm me. thanks

p.s. it's funny cuz those pic mean nothing to me, I don't know parts LOL

make sure make sure make sure you didnt over tighten that tensioner. a broken cam chain is not a pretty thing. this is going off of memory but when i had my f4i i think i read that you are supposed to loosen up the tensioner untill it rattles and then tighten it till it goes away. then back it off 1/4 turn. and make sure when you tighten the locknut that you dont turn the bolt. real pain in the *** given the ammount of room you have to work with but you'll never have to deal with the damn rattle again.

a little rattle is okay. better than over tightening. when i did mine it sounded fine until i rode it for awhile then it was so loud that i pushed my bike back to the truck but then i tightened it up some and havent heard a sound since and that was about 2 months ago.

catach42

yup definitely the same thing (the motors are nearly identical). its a cheap fix and is decently easy to do as long u have small hands or the right tools

thats where i got mine

catach42

make sure you goto your dealer and get a new gasket also

the whole job only costs about $55 and takes about an hour

P-Diddy

all i did was google APE manual tensioner. paid like $51 for it. went to dealer and paid $3 for the gasket.

catch42 - yeah i was thinking just a little rattle is nothing compared to that nasty rattle it had.

all i can add to the questions: if your bike idles fine, then it rattles (not pinging or ticking when revd) then i believe it's the same thing. you could also truck the bike to the dealer, have them listen to the sound and verify it sounds like a rattle. (they should also tell you it's common for the F4/F4i) i figured only cost $50 so it was a place to start. good luck.

I wonder if this thing will help out my 929. Motor was running awsome and still is but just like 3 days ago it started rattling at around 6000-7000 rpm. I wonder if its just that I need to put this on or if I need to replace my bottom cam sprocket. I took the bike apart as soon as it started doing it and checked everything but the cam chain and everything seems to be fine. I dont know if im missing something or what. I may go this route and see if it fixes it.

Do you have to take off anything on the engine except for the head cover or whatever you call it. (My mind is drawing a blank. LOL).

Peace Justin

PS Any incite would be greatly appreciated.

try reving it up, and listen carefully... if the cam chain is loose it will only rattle when the motor is reving down because that is when there is no tension on the chain from the crank, then when you gas it again, the chain tightens and the ratting starts,
if you hear a noise when it revs up than you have a much bigger problem

bikefreak600

and the problem is the chain tensioner goes bad, it is spring loaded and it is a piece of ****. you shouldnt have to worry about the cam sprockets or chain going bad as long as the motor has oil in it

jdridin

Its definitely the cam chain. The engine is running freakin awsome still, it just has that clinging noise comin right from the cam chain side of the motor. It definitely does not sound like a piston or rod nockin and the valves are not making the noise either. I am almost positive it is the cam chain and I really wasnt payin attention to when it was going on in relation to letting the throttle off or hitting it back on. Ahh I might as well order one of these things and see if it works.

Peace Justin

Ohh and I always keep oil in my bike, actually about a 1/2 court over just to be on the safe side. LOL . Let me know if you or anyone else has a suggestion.

Thanks Bro.

jdridin

Well which is it. Does the chain start to rattle when the motor is reving down or when you gas it. You kind of lost me there and it kind of sounds like your contradicting yourself. Ha Ha .

Lata Justin

bikefreak600

oh whoops.. my bad, what i meant was when you gas it again the rattling stops
thanks for catching that, i need to start paying attention to what i type

jdridin

I hear yeah. LOL
