Penton Talk / Front tire selection..
October 20, 2020, 09:26:29 PM
My favorite tire was the Michelin S12XC which was discontinued I believe. Hopefully someone here knows what Michelin tire was intended as a replacement for the S12XC and if it compares favorably.

Penton Talk / New Philly Hare Scrambles

The tractor setting at barn corner looks to be either a 1855 Oliver or a 1955 Oliver. The first model year of the 1855 was 1969 while the 1955 first year model was 1970. Not sure but the model years were probably introduced late previous year; therefore, if it's an 1855 Oliver it could nail the date of the photo as later 1968 at the earliest

Camaro is a 67 as it has a vent glass. 68s had no vent glass.

Just looked closer at the photographs in the just discussed ADVRider post and noticed the bike number plates had Bowman as the rider's name. Great post there good sir.

There's a good post currently  on the ADVRider forum under Riding then Racing done by an avid Penton man regarding his experience at this event. Don't know if he's a POG member, if not, he should be.

Absolute full-on legitimate dry race win by a solid rider on a very capable well set-up bike. KTM has accomplished what they said they would do when they began their MotoGP effort. Outstanding.

Mike Winter - I had a 1983 V45 that "high speed wobbled" at 130 mph also - somewhat disconcerting that was.
I was lucky enough to attend a Kevin Schwantz Superbike school in 2004 at Road Atlanta after the AMA Superbike race. The speedometers were blacked out on the Suzuki GSXR600 school bikes but I felt like I was carrying the mail pretty good down the back stretch before what was the gravity cavity, but a youthful Ben Spies, Mike Martin, Jamie James and Schwantz himself smoked by me like I was sitting still. The school was supposed to be two days but was cut short by a hurricane to one day. Schwantz compressed everything as best he could and gave us about 90% of the content and only charged us 1/2 price. Good man that Schwantz.
Never been able to look at speedometer above 160 on my CBR1000RR  - really too fast for any of our roads around here.
Fastest ever on Penton was first special test day 1 of the 2013 Massachusetts AHRMA ISDTRR. Check-out crew thought event was actual time keeping enduro and were late to  man the check - a bunch of us ended up pretty well tapped out on a single lane fire road through the woods till common sense prevailed - pretty wild that was.

Thanks good sir. I'm in deep Southeastern Illinois and closest town is Eldorado.

Another OTB episode of mine - 2013 AHRMA ISDTRR I was pushing my 74.5 HS to the start from Parc Ferme on day 1. It was a far piece but downhill so I ran/pushed hopping on the bike after achieving a pretty good clip and promptly stomped the bike into first gear with a poorly placed foot. Perfect front flip over the bars landing flat on my back. Quickly jumped up and bowed to some bemused observers., Really made a showing.there.
You fellow Mopar enthusiasts - I'm needing a rust free trunk lid for a 70 Plymouth B Body. Will go on a 70 Roadrunner I'm restoring.

1988 I was riding the KX500 down one of the Delta mine haul roads heading over to the old Ayrshire strip pits (which would later become our club grounds / public riding park - Little Egypt ) for some quality practice time. What looked to be a pile of weathered shale  was instead found to be several truck loads of ag lime that had been there a while. I hit that pile at a fair clip looking to get some "big air". I ended up well beyond the pile and all that could be seen of the bike wedged deep into the pulverized limestone was the tip of the rear fender.
Another memorable episode was when I bought the new 1986 Honda XR250R which had gotten good magazine hype . I had put on bark busters and also a pair of those full coverage plastic hand guards that bolted to the bark busters and formed what amounted to an enclosure front , top and bottom of grip.Flying down a rocky, mildly rutted downhill the rear end started swapping violently with the front end soon tucking. Over the bars I went. Felt like both hands were broken off levering against grip and hand guard. I slammed down chest first further on down the hill with the tumbling bike seeking me out to punish me for over riding it. It landed hard on my back. Good thing I had a chest protector on as it had to have provided some relief. My sternum bone to this day feels weird. Fork and shock springs and a revalve didn't help this poorly geometried pig bike and I didn't keep it long. I crashed hard more on this bike than any other I've had.

Penton Talk / Home Page Photo March 2020

Summer 1977 two riding buds and I were fearlessly trespassing on Sahara Coal  and hill climbing Sahara 5's gob pile. 5 had been running since the 30s and the gob pile was huge. Halfway up was a ditch cut around West side . We climbed up to ditch and stopped. Ditch surface looked dry  as a bone.  Got off my TL125 Honda , found a good sized rock and bounced it off said ditch surface - hard as a brick bat. I wheelied down the bank to get a good run on the rest of the hill and broke through the crusted surface promptly sunching the TL to the tank and flipping over the bars landing on my back getting half buried in the grey gob mud myself.. Took over an hour to extricate the bike. Ruined a good pair of blue jeans and a pair of the tall Dingo harness boots we all wore at the time.The grey gob mud is severely corrosive and you can still see evidence of this episode on the bike's cases - still have the bike and under restoration.

Penton Racing Talk / AHRMA National cc
February 16, 2020, 03:14:19 PM
Here's $0.02 worth:
 Regional modern CC series have Super Senior and Golden Master classes where dads and grandads can race while accompanying kids/grandkids racing AA, A, B, etc. or various youth classes. Events are either day trippers or leave Saturday and camp that night, race Sunday and be back Sunday evening. Driving several hundred miles to attend an event for chasing an Ahrma National Championship that , in effect  is an attendance award, is not a competitive option for a lot if not most of the above discussed potential Ahrma competitors. One possible then would be for an Ahrma regional group to join with a modern regional series to offer Ahrma classes on their race day or day before. Have no idea how AMA and Ahrma sanctions could coexist however.

How did you fix the wheel speed sensor to the fork slider and the magnet to your drum brake hub?

Penton Racing Talk / 2019 vintage enduros
December 15, 2019, 02:27:40 PM
Planning on doing more of these this coming year.  Large fun.
I've got to do a new piston in the IT - ran too hot plug in the one event I did and purt near killed it and didn't bring any colder plugs. That is what I get for not doing hard test riding on a new bike build.
Any one know if enduro computers are legal for this class? I think I saw one in use. If they are I might install myself.
