Strange noise - SV650.org

There is a weird ticking noise on my bike. It is not linked to the chain/gearbox as it does it when the bike is in neutral. Its almost like a clock tick and seems to increase in frequency as the revs rise ( i think

). I think it has become more prominent since i changed the exhaust at the weekend, probably because the exhaust noise is now so different to the engine noise whereas it all used to blend into one.

Is this normal or is it something i should get checked out?

Cheers

Cam chain??

And the noise is normal or it is signifying there is a problem? To be honest although i have heard of the cam chain i have very little idea of how it works

Sorry i would have a look in the on site manual but work internet blocks access to the main site yet lets me on the forums.

My basic understanding is that it is the way to link the two overhead cams of the engine (through the V shape, down to the middle and up). I think they run over the valves/springs closing them again. I'm no engineer see.....

They run on automatic tensioners which sometimes stick, if the chain isnt tensioned it'll rattle/tick. Apparently its easy to unstick them with a screw driver.

Hmmm, this doesn't sound too good, now i'm concerned. Does anyone know where i should wiggle the screwdriver around to unstick them?

It's quite normal, just a little noisy from time to time.

Ok, cheers, won't worry too much about them then although i may get it checked out next time i am back home down at P&H.

I wouldnt worry either.

From what i can gather there is a silver cap/bolt on the top of each head of the engine that you take of and stick a flathead screwdriver in and flex the chain tensioner out and let it spring back in.

i recently had a scorpion fitted and i hear the same... like a very faint tick tick.. almost a whishper but it its there...

Yeah, thats the one, mine has just seemed to get more noticeable recently. As i say i think its partly because of the different noise the can makes which means you notice it more.

The scorpion pipes are good though aren't they, lovely when it pops on the overrun, mainly when slowing down at around 3-3.5 revs in third.
