Fork rebuilding...
I'm posting this on multiple forums, sorry if you've seen it elsewhere...
?
After the "fork oil stink" thread which discussed some interesting things about fork internal parts, I've begun dismantling my forks for a service... can anyone advise regarding the "fork inner pipe" (as the parts book calls it)? I've disassembled things as far as the service manual and other online resources suggest, but there's still some bits at the bottom rattling around on the inside, which aren't shown on any diagrams I can find. They aren't mentioned in any of the written or video tutorials I've seen. I see no obvious way of removing them (no retaining rings, etc). The parts in question are inside the bottom of the main tube, concentric (if you will) to the bushing. That's what's shown in the photos, you can see the approximately 1-inch-wide relieved external groove where the bushing seats:

Here's a link to a short video I made showing the bits and their movement:

I was under the impression that these forks were pretty much a universal design; I've seen video tutorials for other bikes which appear to have identical parts... but no mention of these components...Do I just do my best to clean everything with those bits in place and reassemble, or is there something else I should be doing here? |

Re: The sound of silence
yeah those are original
its impossible to say if those pipes have been molested, but my guess is not.
thats what the end of the mufflers look like with the baffles intact.?
you would have to get deep in there to see. it requires a long drill bit.
i cut mine off at the join, welded the inner to the outer pipe, and have a set of slip ons that are identical to the?
original mufflers, but good and loud!?
i can? put the original ones on if i want a quiet ride, or a set of short sporty ones when i go offroad.?
it only takes minutes to swap out the end cans.?

Re: The sound of silence
Kia Ora mark,?
Are your pipes original? Headers and mufflers one integrated unit?
You probably know that they are actually a pipe inside a pipe right??
Mine came unstuck at some point, I had to cut the mufflers off to be able to reweld the inner pipe to the outer pipe (it was rattling around inside)
Anyways, I'm saying this because after that happened, I have been free to try out all different kinds of mufflers on the bike (slip on cans) to get the right sound (and look)
Now I have cans for when I'm blapping around my local area,(real loud) cans for when I'm on tour, and something in between! ?
It's been a lot of experimenting.?
Theres some interesting stainless units getting made in Thailand, they look the business, and sound good too. Probably too loud to be legal, but I guess it depends where you live!?
I haven't tried them, I have been asking around this forum before, but apparantly no one on here has ever installed them. Beats me.? |

Re: The sound of silence
Harbor Freight (aka Hazard Fraught) has a set of "use once" 25" long drill bits for $15. I drilled a hole as far as I could get into the center of the mufflers and now it makes a nice burbling sound that isn't loud enough to be obnoxious.

Re: W650 oil consumption
I have always used Shell Rotella 15 40 with great success! More cost-effective than those fancy brands with motorcycle graphics on the bottle. It's JASO rated for wet clutches. Kawi claims you can go up to 3500 mi before changing the oil but I live in a hot climate so I never go past 3k. They also state change the filter every other change.

I have used Shell in my previous vintage ride and never had any issues either. Oil threads def start a flurry of responses and opinions, so this is my quick .02 |

Re: Bought this a few weeks ago
Cheers. I will see if they are available here.?
I use Autosol for metal polishing which is pretty good and have started treating the rust with CRC rust converter.? Thinking about options to tidy up the frame without dismantling it as I want to keep riding throughout summer and autumn (and winter tbh). Roads aren¡¯t salted here so assuming it is just 25 years of wear and questionable finish.? |
