Hi Guys,
I know its a bit rude to introduce myself with a problem, but im at my wits end with this one.
The problem in question is a 1999 TE610E (not so much a motorcycle as a paperweight at the moment)
I few weeks ago my bike exploded its automatic decompressor. I found it mangled into pieces lying underneath the flywheel.
At the same time that this was happening my bike had slowely developed a loud rattle at low rpm that i was sure was the timing chain. I think that running the bike with the loose chain caused the auto decomp to stress fracture.
I replaced the auto decomp with a new one.Cam gear, bearings and rockers all looked fine up there.
I replaced the cam chain and the auto cam chain tensioner with brand new ones.
Replaced reed valve as it was word around the edges from the loose chain.
I reassembled everything and started her up. The bike fired up easily as soon as fuel got through, which means that the auto decomp repair was working properly.
I noticed a rattle that sounded like the timing chain. Damn.
Took it for a ride for 10 minutes. Full power, evrything fine, except this rattle.
The rattle is not at idle, but if you snap the thottle you can hear it clearly for 5 or 6 seconds and then it stops. If you rev it hard and hold it you can hear a constant rattle.
It sounds like what the old timing chain sounded like when it was buggered.
I put in a brand new oem timing chain and brand new oem automatic spring loaded cam chain tensioner in and they have only been run for 10 minutes.
I dissassembled it yet again to have a look at whats going on. Everything looks fine, i dont understand what the noise is coming from.
Someone has suggested that the timings gears themselves may be worn, but the bike has only 9000kms (5000miles)
Just hoping someone might be able to point me in a direction.
I asked this on thumpertalk aswell, sorry if someone had to read it twice!
Thanks,
Pete
