I am having some timing chain noise. I'm a timing chain adjustment noob. The manual leaves out some detail.



I slowly loosen the 12mm jam nut ( this spins the bolt with it) a half turn or until the noise goes away. ( I have done this about a quarter turn, the bike still has chain noise but started to sound funny)



I stopped here.



Anyway - after loosening the nut a half turn , then remove the tensioner cap bolt and tighten the tensioner until the noise disappears.



This is where the instruction ends



Do I then need to tighten the adjuster jam nut while holding the adjuster bolt still? or do I just tighten the jam nut and not worry about the bolt.



Maybe this is overkill, but I'm at work right now. why not ask.

Thanks for the help.



Side note, if the timing chain were to break / skip teeth do I crash a valve into the piston ?

It shouldnt be that tough- unless your chain is really stretched out or the teeth on the gear are worn out. You just loosen the nut, tighten until the noise stops and at the same time, re-tighten the nut. It shouldnt take that much effort unless the above issue is the problem.

"You just loosen the nut, tighten until the noise stops and at the same time, re-tighten the nut"



tighten the part under the bolt cover until the noise stops ? or are you talking about the bolt that the nut is holding in place ?

Loosen the 12mm jam nut, loosen the slotted stud about 1/2 turn, take off 14mm plug on the bottom of the motor, turn the slotted adjuster under the motor in until the sound stops, replace the 14mm plug and washer, tighten the slotted adjuster on the side until it's snug, then tighten the 12mm jamnut. If the chain and sprockets are in spec, this will stop the noise.
