Penton Talk / Re: John Penton signature hats...
Last post by Mike Lenz - February 24, 2025, 11:07:48 AMJust ordered a hat and was asked for more verification to log in. May have made a mistake logging in. But I did not receive an email as it says I was supposed to, and I just verified my email was correct. So not sure whats going on there and you may want to investigate. TY Mike

Penton Talk / New Message Board Testing
Last post by Rob Hugo - February 22, 2025, 07:17:50 AMThere was a lot of talk earlier about the software on this Message Board not being as easy to use as some people want. I have a setup a temporary server with new software to test. It will function more like what you may be used to on platforms like Facebook.
Would appreciate it if any of you regular users would want to test it out and give it a good prodding to see if it is more along the lines of what you want.
If you are interested in giving it a try, reply here and I will get in touch. Thanks!

Last post by ALB - February 19, 2025, 10:52:18 AMHi Carl,
If you have not found a replacement bearing plate, give me a call. I have a magnesium one and a plastic one (like the lower one in your photos) in my inventory.

Penton Talk / Re: Just completed 1973 125 Si...
Last post by michajon - February 11, 2025, 10:35:54 PMThanks for all the really nice comments. It all helps make the experience even better.
The question about the carb adapter - using a lathe, I shortened the carb exit and turned the O.D. Then I made the stub adapter. It slips onto the carb exit and is bonded. It's now part of the carb. The other end going to the cylinder has an internal O-ring to seal with the intake manifold tube. The bore is tapered match the two I.D.s It is split so the clamp grips the intake manifold to hold it in place.
The question "what was the biggest challenge?" - So many challenges! Aligning the clutch plates and getting the clutch back on the spline is a challenge. Most things are not so much difficult as they are just very time consuming. Painting the tank, air box, and side panel for example. Doing it myself was a couple of weeks. I built a make shift paint booth in my back yard. Several trips to the automotive paint store finding the color. FYI - the brand makes a difference too. Prep, paint, clear coat, decals, lots of steps. Swing arm bearings require a substantial press (not just a hand arbor press). It also requires a proper support. So making some custom tooling is sometimes required. You may need to make bushings for the shocks; heat form, shape and match drill fenders; straighten and or weld some parts. It all depends on how complete and what condition is the bike or parts you start with. It can be very satisfying. Here's a couple of progress pics setting the timing and fitting the rear fender and exhaust.

Last post by KJDonovan - February 11, 2025, 02:03:15 PMGreat looking build! What did you use for a spigot adaptor for the Mikuni? I can't quite see it in the picture.

Penton Talk / Re: Is this in decent shape
Last post by Admangia - February 10, 2025, 07:13:24 PMAll your posts are both edifying and solidifying my thoughts on restore Vs. Meticulously service, detail and gently ride/bring to gatherings. Everyone one who responded I want to thank so much. I sent a response to another Penton owner who appears to have set a bar on detail! Beautiful. I will take recommendations and enjoy getting cleaned up, ride ready and head out see how it feels. I am honored to have been given opportunity to have this sentimental and important piece of MX. history handed over to me!
Thank you, more to come as I attempt to get it cleaned up and going late spring then possibly off to vintage ride Soringville, NY (zoar valley) this fall. That would be timeline goal for "go live".
Ty, Andrew
