There is an old saying, "You have to first finish before you can finish first." (or something like that...)  Please, shift gently and deliberately.  Sachs transmissions were not designed to "bang gears".  I raced Pentons with Sachs engines for over seven full seasons of MX and Hare Scrambles and NEVER damaged a selector key.  I am sure many other Penton racers and riders can also claim the same.   As you well know, a damaged selector key can do serious damage to many other transmission parts.   Joe  p.s. it is not the "22 H.P. 100 that is eating the selector keys for lunch" because there are many Penton 125's and Sachs 175's with greater power with no transmission problems...

update ...... motor had a repo key. The bike is now set up with a JPMORGAN-SUPER KEY . I dont think Mickey rode a sachs back in the day. He is learning the vintage deal the hard way. His motor has been to the East to South West and back North . The first Sachs tech miss alot of internal faults in the motor, the second Engine Pro made things right but was unaware of the bad keys. The motor has been in the mail trucks more time than on the track.  He will rip things up next year. LG

Is that 22 HP at the countershaft?

It was nice to see a few more pentons up this way, it was a great day, the track was near perfct. They have been racing at that track for many years, if you look close you can see the remains of a 1/4 flat track..so I think they have been racing there since at least the early 60's maybe earlier..

The more the story is passed along facts get stretched a bit;). That would be the claimed HP. We don't know the actual HP output. I would say close to 20. The 100 of Mickeys walks away from my 125 GS and any other 100 or 125 it comes across, most evo class bikes too. You 100 guys make sure you run a 3.50 rear tire. LG

LG,
 Do you or anyone on the board have a good source for 3.50 rear tires?
They are hard to come by and what my 72 ,100 came with stock.
thanks,

John,

Cheng Shen and a couple of other crappy tire makers have them. They look good but don't stick that well or for very long anyway.

Not trying to throw Larry under the bus, but I have a 4.50 Kenda on my Harescrambler and a 5.10 on my 390 Husky.  Both tires hook up well and have worn pretty well for a guy on a budget.  Just my 2 cents worth...........

The other way to go would run a 19inch rim and a Maxxis tire, some of their line of 100/100 in the 18in size are not as wide to other brands. Or run the cheapo's or one that is to large. Would have to say the cheng shin works good on a good soil track ; a harder packed soil is another story, you can feel the knobbies roll in the corners[:0]. But we still run them . Its only five laps and we get the hole shoots.[8D]LG
