Hi Bob,

Thank you very much for sharing your experience.

I'm sorry for posting my tire question in the wrong thread. My English isn't very good, and I misunderstood the topic of this discussion.

I'll start a separate thread to ask for tire recommendations for my R65LS.

Thank you again for your kind reply!

Best regards,

I had one shop replaced a set of Lazertec tires, there were tubes installed on the old tires.
They didn't put tubes in on the new tires.
The front had no issues, the rear tire lost 4 psi around 12 % every week, had a tube installed on the rear .

Front 90/100 and rear 4.00 fit fine.
Handling is about the same as the Lazertec tires . Better handling in cold temps for the first 10 miles is so that the Lazertec tires took to come up to temp .
I live in a low desert and I have no clue as to how they are in wet conditions .
Yes I run tubes with these.
I had issues with Lazertec tires with no tubes .

Hi Tiedie and all. First thank greatly for the resistors but as it turns out I didn't need them. I had already  carefully cleaned and lubed the speedo. Hardest part is getting the bezel on and off but ultra sonic clean and reassembly went well. As far as the bouncy tach I like you went through all the contact points and cleaned them up and a new smear of dielectric grease (Dow Corning 4 Electric Insulating Compound) This is from Snowbum's excellent article on electronic tachs.

"Problems in bike's wiring &/or in the ignition circuitry; even some green corrosion in the ignition coil towers or kill switch, etc., can cause weird readings ...be sure those are not the problem!  Only good way to be sure the KILL switch is not at fault is to bypass it, temporarily ....although if cleaned, and then symptoms gone, you found the problem.  Green corrosion is particularly annoying and problematical, as it can help create a 'diode effect'."

There was a bit of corrosion on the coil connections but my last stop was the kill switch. Took it apart and beside a dead bug there was a good deal of green corrosion on the copper disk meeting with the steel spring. 30 years in a shed took its toll. Cleaned it all up as above and yesterday went on a 50 mile test ride. Tach and speedo were perfect! As new, solid and not a hint of wobble. Call me a happy camper.

Hi Bob,

I read your posts about using Metzeler ROADTEC 01 tires on your 1982 R65LS.

I also own a 1982 R65LS and am very interested in trying these tires.

Could I ask a few questions?

Are you using a 100/90-18 front and 4.00-18 rear on your R65LS?

Does the 100/90 front fit the original 2.15-inch rim without any clearance issues?

How does the steering feel compared with the older Metzeler tires? Is the bike light and natural when leaning into corners?

Are you running the tires tubeless, and do they hold air reliably?

I'm currently using Continental ContiClassicAttack radials, but I previously enjoyed the natural handling of a Dunlop F8 front and Metzeler ME77 rear combination.

I'd love to hear your impressions of the ROADTEC 01.

Thank you!
