Title: 87 k100rs chain tensioner question
Post by: timewolf on May 29, 2018, 12:50:28 PM

ok , gents here is the latest question .


I've got a noisy timing chain ! it rattles only under load ( when riding ) rev it in neutral and she is silent. any one else have this happen ?


i replaced all the plastic guides, and the arched tensioner above the hydraulic tensioner .
to no avail . i bought a new chain but saw it was the same length as the old one. so i returned it .


I'm thinking maybe I'm not getting enough oil pressure to the tensioner  ?
Do the springs fail ? do the tensioners go bad ? ( eroded oil journal ?)


I'm at a loss .  everything on my bike is so well maintained and looks great ! so much power! she kills! but that chain rattles its painful! i will not ride till its fixed!
PLEASE HELP WITH YOUR EXPIRIENCE AND KNOWLEDGE

How did you measure the old one for wear?

thats a good question... im nervous for the judgment about to come my way!!!
i laid them side by side. and pulled they looked the same.

If you're in that deep might as well received place the chain.
