Scott,I am supposed to have one (at least) in a huge tub of parts i got from an old Mettco buddy of mine.Problem is i don't know the contents of the Koba kit-so if you know,or better yet have a list of the kit contents so i know what i'm looking for,i can search "the Tub" and see if i have one.I'm long overdue in going thru that stuff anyway.Or if anyone else knows,please let us know.Thanks,
Ric

Ric,
I will see if I can find pictures of the entire kit. I am selling all of my old library and know it is in there. I will try to get back with you by Monday.

I sent one to Scott, but was missing a round shim, looks like a wedding band. He needs the install instructions though.
Ric, consists of spring loaded shift (selector) shaft with machined key and special selector boss and the ring like shim.

Ron,if you do find one and can shoot a pic that would be cool.I'll call you in a bit.Thanks,

Scott, I have carefully, over the period of a couple of years of racing my Penton 125, figured out why the Sachs transmission is so hard to shift. The answer is that there is no 'drop in time' which can be compaired to the back and forth movement between the dogs on a 'normal' transmission. This movement means there is time and space to go from one gear to the next. On the Sachs transmission, the drop in time is the clearance between the shift/selector key and the openings in each gear, which is .010" or .025mm!!, not much at all, it is a wonder you can ever shift. What I do is send the gears, usually 2nd through 6th, to be EDM cut so there is about 2.5mm of clearance, 100 times the standard. This makes a huge difference. I did a set for Tom Benolkin and he said it made a "500%" difference. It isn't cheap, $60 a gear, which is my cost. This is the only true 'fix' for the Sachs transmissions. I have looked at the Koba kits, and while they are a band-aid, they don't heal the problem. I can be contacted at 415 822-1315, or

JP - "Drop in time" -- very interesting. The only "real" problem I have shifting my Sachs engines is that critical down shift from 3rd to 2nd going up a hill when I've messed up and let the engine "drop off the pipe." As you know, a missed gear up hill turns ugly really quick. Gravity is always ready to suck you to the bottom. I jab down on the shift lever hoping (desperately needing) to snag 2nd gear and get back on the gas. When I jab down, all I get is high revs. What I found out this weekend is that instead of "jabbing" -- just a light touch to knock 'er out of 3rd is all that is needed along with a very slight pause to allow 2nd gear to get engaged, then back on the gas. I think a gear box with added "drop in time" would help with the above. I'd like to experience (ie ride) your bike some time. Thanks for sharing and welcome aboard.

jp morgen! i have heard great things about your expertise on sachs motors and if i recall ktm motors as well. i had kevin peltz as a guest over the portland weekend and he was singing your praises too. welcome to the pog site. i'm sure that you will be a huge asset here. my friend, kevin outland recently bought a 74 125 penton and will be rebuilding it into a race ready machine. we'll be in contact about your trans mods. hope to see you on this site often.
oh yeah, scott wallenberg, its great to have you here too, you are lengendary about those old monarks.

Thanks

I must say I am pleased to hear Kevin Outland has bought a Vintage Penton. Kevin and I raced many races at Meadowlarks along with his brother back in the 70's. Kevin should remember me, as Jack Horinek and I used to chase him around many times on the local tracks.
Hello Kevin !
Sincerely,
Victor Monz, Hemet, California
Ric Emmal:
I would be glad to come pick up you tub of METTCO stuff and sort out the KOBA Shift kit, of course there probably won't be left much in the tub when I'm done. Just trying to help.
Be Well.

Victor,You'll have to get past Malcolm + Mert's sniff search(my two golden pups) on the way out of the garage though!Actually i found what appears to be most of 1 kit and still have stuff to go thru-finally it's cooled down here so working in the garage won't be so brutal,when i have time.Hope you leg is healing ok-On the meds a 2 to 1 ratio of Fat Tire beers to Vicodin works pretty good to get comfortably numb[8D]!Later,
Ric

If you do find some goodies, you may not want, please let me know.
Thanks for the medical advice...only Vicodin makes me think I can kick over my 250 and go for a ride !
Victor
Victor,What are you looking for-anything in particular?Maybe we can do some horsetrading.Later,

Hey ric, how is Mert. As I recall he was real sick a couple years back, but was getting better..... valley fever I think.... As it turned out the doc told me that at one time I had valley fever and it left a very small knot in my lungs... nothing to worry about now... lung are clean and pink. Must have been all that riding in California way back when..... I don't see much dust up here in Washington... mostly mud and sand....

Hi Thom,Mert is doing ok-except for the ocassional seizure(about every 3 or 4 months)which meds have kept under control.Valley fever had spread to his brain,leaving a leasion causing that-but as long as he's happy and not suffering too much he'll be with us for a long time to come.In fact him and Malcolm are reminding me right now that it's playtime,so gotta go throw the tennis balls,then out to the garage for some wrenching!Thanks for asking,and i hope all is well with you and yours up in the great northwest!
Ric
p.s.- no extra Koba kits,i've only found the one and i'm going to try it and see if it makes a difference or not.
