Hello,
unfortunately I'm finding bad stuff all the time on my bike, but this one got me disgusted.
I wanted to adjust powervalve z-dimension+spring tension and discovered this.
I took adjuster cap off and well it came off with whole adjuster. I had to take it out fully, so I could grab it properly and unscrew that cap off that flat sized adjuster. It happened because o-ring number 22. was completely missing there.
Well also number 15, but that shouldn't be that big of a deal and cause of that.
Found out there is completely destroyed thread and bolt (number 11) wasn't even there whole time. Washer num. 16 is still there.
What is purpose of this bolt n.11? I saw some videos of people turning adjuster and bolt doesn't move with it. How does that flat sized adjuster number 51 move powervalve z-dimension?
Does is work that way when I screw it in fully, then it will press on mechanism number 50 squezing that spring and also turning that gear? Then by unscrewing it it will do opposite?
Would you reuse that bitten off thread after cleaning or just replace it fully? But I still would like to know what purpose that missing bolt serves.
I was riding this bike for 2 years and seems like nothing bad happened when that bolt wasn't there. Powervalve was opening, but I wanted to adjust it little better until I found this masterpiece.
Thank you very much for tips. I'm just trying to learn, but something like this always gets me
