Are there any available sources for Penton/KTM 250 clutch plates for 73-77? I have a 74 1/2 250 that is badly slipping the clutch, running ATF, and another 74 250 engine that Gary Ellis and I have used all of the useable clutch plates in my Drag Bike Project engine. The part # for the 7 discs are 54.32.011.250 and the 8 flat steel discs are # 52.32.009.100
Thanks in advance for any assistance in locating replacements.

Mike,
Have you thought about checking the clutch plates that are in the engine that went with the Kenny Robert Flat Tracker? In addition I will see if any of my buddys have any spares.
Ron Carbaugh
I was holding off on that in case you wanted the engine, depending on its condition. If there are no sources for new clutch discs, has anyone tried to send them to someone like Barnett to have them produced? Mike

Mike, I may have another clutch stack in the shop, what thickness plates? Tom Brosius
According to my Repair Instruction book, the 250 clutch discs are 2,75mm thick and the 400 is 2,50mm thick. I have 3 or 4 NOS 400 clutch discs, but not enough to build a 400 clutch pack, and I need as many 250 discs as I can get for 2 bikes currently.
The flat steel discs for a 250 are 1,50mm thick and the 400 flat steel discs are 1,00mm thick.
If I can come up with at least 1 NOS 250 disc and one of each 250, & 400 flat steel discs, I would see if Barnett would like to produce them, since they offer other vintage bike clutches. Mike

I have just what you need....but the shipping might be too much from Southern California and I think they are going to a closer spot by this weekend, oh and I wouldn't want to, as you say "back out of the deal".
Sorry Mike.

Hey-sus, talk about things to be done, I have the following to do:
Attend the Nats at Two Rivers this w/e "Trials" and dig out the Patriot to honor Jim Pomeroy with our friend Corky Root. Ship 4 side panels and MC5 decals to Mike Husted in OK City for the RR, oh but if you knew how busy I will be, then after that, re-assemble the "bagger" on Sunday so I can relax and enjoy the changing Aspen....
Would it be worth it? you can bet your money on it :D
gotny other stuff for me to do?

Mike Winter, for your enjoyment, there is a very good article re:clutches, written by Bobby Lucas in the Fall 1999 Issue #4 of Keeping track. He denotes plate thickness:
125, 175, 250 MC organic at 3.5 mm, my deduction, is that these plates are the newer organic angled plates that spin the oil away from the inner hub
250 Enduro plates, of brass, rectangular tabs, are 2.5 mm in thickness
400 Enduro/MC plates are 2.0 mm with shorter springs and 1.0mm steel plates indicating a larger clutch pack in general.
In short, I am not an expert re: clutches...but there is a good amount of information.
Hope all is well!
Respectfully,
Tom Brosius
Mike,
Mike you can go to home and then publications and print out that article. It takes a while to download, but it ia worth it. We can thank Don Roth for the help in getting the old issues on the site. Or should I say "thanks Don".[^]
Ron Carbaugh
Thanks Victor, that's OK, you crack me up. Maybe we can get together on something in the future. Mike
Tom,
I'm attempting to download the article so I can learn about the newer clutch discs and how their application might benefit myself and others, but at dial up rate this will probably taks until this time tomorrow to download, since I live in the dark ages, or so it seems. No DSL available in rural Newton IL. Mike

Mike,
If you need me to print and mail it to you no problem....just let me know. Watch that Victor he is a city slicker originally from Cleveland and raced with the Penton boys way back when......Victor is a good rider and good Friend.

EMGO can have any clutch plate reproduced for us but you have to order thousands each. I was willing to do hundreds but cannot afford thousands. Pretty reasonable prices, way cheaper than anyone else as I checked it out at the dealer show earlier this year. Al considered going along on this but currently spread too thin on other purchases. I also checked Metzeler on tires for vintage bikes, normal markings, i.e. 3:50x18, 3:00x21, 4:00x18, but they didn't want to talk unless you were ordering thousands each. All it takes is $$$$$ but it can be done!;) My hat is off to anyone having parts made for us, it gets pretty expensive!
Kip,
You have mail! Mike

Sheesh, Tom. OK City? I'm not sure how I should take that up here in Tulsee-Town. Have fun Trialin'.

Mike:
When the fun stops with my Pentons, I hope it's either when they are shoveling dirt in my face or I'm hooked on lawn bowling or shuffleboard!
Take care.
