Hello, I've been a lurker for years on the site. I raced a Penton 125 back in 1974 in the California desert and owned one in the mid 90's. One of the best machines I have raced over the years.
I have been searching for another one and a mostly complete 1975 KTM 250MX fell in my lap this past week locally. I can't wait to learn from the members here on some questions I will certainly be asking.
I know a couple of members on the site, Mick Milakovic and Ron Carbaugh, that I have seen, maybe more. I worked for Curnutt Shocks back in the day for quite a long time and am rebuilding them for the vintage and post vintage racing guys. If I can help you out let me know.
Thanks for having me

Scott does beautiful work on Curnutt shocks. He has built many set fro me and my Friends and the finished product is Great.
Ron Carbaugh
Welcome Scott!
Looks like you've got "the bug" - it leads to an expensive addiction.
Let us know how we can help.

Scott, welcome from all of us!

Welcome! Do you have the porting and pipe specs for that engine? Works wonders!!
Thanks for the welcome guys. Right now I am figuring out the puzzle as this bike was taken apart from the PO. I have most of it identified.
Does anyone know what the squish is for this motor? I was told .030 and no less than .025.
Thanks in advance.

Hi Scott,
Good that you are back to Pentons. Post some pictures of your project, that livens things up. Do you have a manual/repair handbook for the bike? If not, it's a worthwhile investment. Al Buehner (http://www.pentonpartsusa.com/) is selling them. He is also a good and reliable source for parts.
Cheers

Thanks Clark, you have no idea how bad I have the addiction. I sold my first collection of about 50+ bikes back in 2000. I started again about 5 years ago. Some people just don't learn. Ha Ha.

Hi Andreas, yes I picked up a KTM motor manual and a Penton manual so I think I am good to go. I just picked up some parts from Al this past week. Here is a pic of where I am on the bike after about a week and half. The important parts of the bike are in great shape. I found out that the PO had taken the bike apart in 1976 to freshen it up and fell in love and moved and left this in his mom's garage until 2 weeks ago when I got it.

Thanks JP. I don't have those specs. My first priority is to get the bike complete and go from there. I would be very open to seeing them though. If you could send them electronically my email is
[email protected]Thanks
Scott great history and looking nice like all your builds.
Ron Carbaugh
This looks very clean! Is the motor already in good shape or do you plan to go through it? I have a Penton just like this but in pieces, it will be my next project.
Have fun!

Since my last post, my wife decided we are moving. So I haven't had much time to work on anything until the past couple of weeks. I got the wheels done and some other odds and ends. I will be getting ahold of Al B. this week and get some more parts ordered. So far the bike is going together real well. Here's a pic. Not the greatest but.....

Deck height .052 is the sweet spot, from top of the L ring.
Hi I just decided to sell my 1976 mc5 -250 call for pictures it's in very good condition I think you would like it
Sorry I forgot to give you my phone number I'm old 209-603-2038
Louis I'm not really interested at the moment. Maybe later if you still have it.
I've had a little time to work on the bike, I'm also in the middle of remodeling a house to sell. I have a few more little things to finish up and I may start it next week. I rolled it out of the shop today. BTW that is the original paint on the gas tank. I used some plastic polish to restore it.

I also forgot to say that this bike came in 5 boxes completely disassembled. It's been a fun puzzle to put together.
You did a great job. Considering all the work buying a house and gettng the old one ready to sell I would say fantastic!

I forgot to post the finished bike as I have been busy the past few months. It started on the first kick and I rode it around the hood. These bikes are very fast compared to other makes I've rode. I may try and race it next month if the weather gets better and I get some time to ride.

Thanks for the pictures Scott. Beautiful as usual for you. I Pray you are feeling better my Friend.
Ron Carbaugh
It looks almost exactly like the one I had. Back in that time 75_76 it was faster & better handling than any of the other 250cc bikes! Brings back great memories![:p]
Beautiful Scott, you're gonna like it!
Mick
I'm surprised nobody has mentioned this bike is NOT a high breather frame. I've only run across one other one last year when I worked on a 76 400. What is the frame serial number?

Here's the frame #, 54506 84855.
