Rattle at 5-6k under load?

[Taipan]

Hi All
Just been out on my Sv for the first time in a month. The bike has sat unused during this time. I gave it a handful of throttle and noticed a pronounced rattle between 5-6k? It sounds like its coming from teh front of teh engine but can't be 100% sure?

First time I've ridden it without a race can on so I suppose it could have been there longer? Any ideas on what this could be?

If its he cam chain can you reset the tensioner? How much are new ones?

Many thanks

probably cam chain tensioners, is yours a pointy or a curvy? curvy ones can be reset and a popular mod is to fit the tensioners from a 2003 pointy model to the curvy as they auto adjust so to speak

At least I'm not alone with it then!:p

Mine is a curvy. Looks like I'd better research how to reset it. What a time to go I had someone coming to look at it too. Typical :rolleyes:

I think theres a guide some where on the forum how to reset it, the home page i believe

Interesting?

Found the post below ad will try that this weekend. Is it as easy as it sounds? Anyone else done this? ANy reason why i shouldn't do this?

to reset you don't need to remove the tensioner itself.

take the central bolt out, using a small electrical screwdriver (careful not to damage the thread for the bolt), incert it and you'll feel it engage with a slot (you can't see it), turn the screwdriver clockwise (as in doing up a screw), you have to hold tension on it as it retracts the plunger against the spring inside, once it won't turn anymore, "sharply" withdraw the screwdriver and the plunger will "flick out" to the right length.

and that's al that is required, it's worth doing this at service time anyway as it keeps them from seizing up.

Cheers Mark.

Best bet as per the thread jonny posted drop the oil firstly and see what happens

Jonny did that do the trick on yours btw?

Haven't had the chance to do it yet.

Infact i'm feeling rather lazy, i'm seeing spannerman soon so he's gonna do me a service at the same time as other bits and bobs. Can't be bother wasting oil and time when it's just gonna be done again in a few weeks.

Will post what the bike feels and sounds like after that.

I have literally just changed the oil and refitted the standard exhaust. This is the first time I've noticed it but just may not have heard it before due to the race can noise? I'm going to try the method described by rictus above and hope that works? Got a couple of people asking about the bike now but can't sell it with that rattle.

Due to time restraints I've not been anywhere near my bike for ages but thought I'd start it up tonight. Before I did I thought I'd try that pushing it backwards in gear thing. Didn't work. I can hear the rattle if I rev it whilst standing next to it. Also it is tapping a bit on idle. Does resetting the CCTs cure it completely? Or is it just delaying the replacement of the CCT(s)? How much is a CCT?

Check valve clearances, if they need to be done I think they can cause the engine to rattle.

[andrewsmith]

full kits are about 80 quid (if my memeroy serves me right) check wemoto to confim that.

If you do the cct's u need to the clearances at the same time. If you don't want to do it, contact spanner man as he's London based

Since removing my exhaust last winter to clean it up, i also get a tinny rattle from the front cylinder.
Further tightening of the exhaust manifold nuts has reduced the noise a bit. But i think that i should have changed out the exhaust gasket.
Maybe something worth trying ??

Would be worth doing as it should be done as practice.

So if you take the CCT out and strip clean and reassemble is that a near a permanant fix as a new one? Or do they stick as they're at the end of their life?
