anyone know about oil fed cam tensioners?

the 00 740 section is dead so i figure id post this here. on my 00 750 it has the oil pressure type of cam chain tensioner. once the bike warms up it tends to make the timing chain whine a bit. i think the oil press gets too high, i took it apart today but it basically consists of just a spring and oil press line so there is no where to turn it back a bit like the older gen tensioners , is this gonna harm anything or should i just leave it go? its not whining very loud but its def a new noise that was not there before and im not sure why . before it used to have a bit of chatter from the tensioner until the bike warmed up and then it would get quiet, now its quiet from the start and after about 130* i get a bit of whine coming from the chain. ???

I'd say look to wear parts such at the cam chain, chain guides, and chain tensioner, before looking to oil pressure..

Re: anyone know about oil fed cam tensioners?

its kind of starting to bother me. i been hearing this noise for about a week now. i drained oil today and no shavings or anything. it just sounds like a whirring noise but only once the bike is above 130 degrees it starts getting loud enough to hear. when i listen with a stethascope i cant really say where its coming from . i hear it in the timin chain area and also hear it on the other side of motor too. it sounds just like when a belt on a car is overtensioned and it whirrs when you rev it up. it has to be some kind of bearing or something that spins with the rpm of motor

Re: anyone know about oil fed cam tensioners?

since the noise is annoying i took apart the stator today to see if it was rubbing or burnt. eveything looked fine. i also pinched shut the oil line that goes to the cam tensioner while the bike was runnin and the noise still didnt go away so at this point i have no idea. it def sounds like its coming from the upper half of the motor but i dunno for sure..

I have heard the oil pressure fed ones (next gens) are actually worse than the srad ones but can not say for sure.
