Re: Duanes website

Link works fine for me with Edge.

Some of the updates on Duane's site are as recent as Sept 23 so I can't imagine he would still be putting the effort in if there were no plans to have someone continue hosting it.

Re: Introduction and R80/7 ex police bike

It does look tidy and I think you got it at a very good price.

Re: That's AI for you

Artificial Intelligence. Well the Artificial bit is true enough but not the Intelligence. All that Google AI seems to do is search the web for texts on the chosen topic and string them together. If you search again on some of the text strings you'll find the original article which it copied. It's re...

Re: That's AI for you

Every time I search for anything on google the first return is AI generated and it's nearly always wrong in someway, regardless of the topic. If this is what AI is going to do for us then it's going to cause all sorts of problems if people believe it as gospel.

Re: El Cheapo CV40 carb kits

What the.......?! Looking around for carb kits for the '84 RS and this link popped up. Considering the high prices these days, think I'll order a set and look them over. Amazon link.... https://tinyurl.com/2hr7h56k I've seen the same kits on Ali Express so there can be no doubt where they come from...

Re: Tuning.

I spent a little time just feeling the tension on the throttle cables and adjusting them to something that felt equal enough with a visually equal lift time. Once running it seemed the cable adjusters were very close but still took a little bit of back and forth between sides. I use the knitting ne...

Re: Where to find fork piston rings

Jbeebe, I have the exact same forks on my 79 and have been inside them many times so if you have any others issues just ask. After you reassemble the damper valve body in the bottom of the stanchion, check for the presence of a shim and that there is no vertical play. BMW modified this assembly seve...

Re: Where to find fork piston rings

I found the data for type 247 forks and the answer is they do have the same internal dimension of 28 mm so the piston rings should be the same.

Both sets of data were taken from BMW training manuals so should be accurate.

Re: Where to find fork piston rings

The question is are the 36mm R65 stanchions with 28mm inside diameter the same as the type 247 forks ? See R65 data from BMW below. Another issue is I recall reading that after market piston rings were problematic being a little too big resulting in excessive stiction so be careful about replacing o...

Re: Front Fork Seal Replacement 86 R65

Have a look at the parts list section 31 and diagram #31_0362 item 2 which is the fork seal and there does seem to be what they list as a spacer ring.
