4130 Chromoly Frame ATC250R

[El Camexican]

You never hear anybody speak of shot peen. I worked in a shop where we did shot peen on aircraft parts. That would be a great investment to a freshly built raw frame. It releaves any stress in the steel from welding, reduces cracks drastically and is affordable.

Good point Sr. Loco. We had a stress relief oven large enough to fit a 5 ton dump truck inside. It's main function we stress reliving electric motor housings, but we also used it to stress relive billets for some larger frame components and on all our jigs before we machined them. It makes all the difference in the world to the finished part.

I think shot peening is as you say would be a great option for light walled stuff like this frame in this thread. We contemplated putting some used chromoly bike frames in the oven, but decided they would likely come out like pretzels The trick there is to relive the welds with a torch one at a time, but I never had the nerve to try it on an otherwise good frame.

I have been talking to Dave about building this same exact frame only for the cr500 since there's already more motor room in this frame! He is a little worried about vibration but is looking into it.. we shall see soon!

I see one of these in bkm's future.

[JasonB]

interested in the cr500 motor option lol.

Anybody know what fork rake this is 85 ,86 or something else?

[slashfan7964]

That's a good question. Probably 85 but no way of knowing.

According to Dave, his jig was built off an 86 frame.

I'm saving up for one of these. I hope to have one before summer if he's done with testing. I emailed him yesterday to ask a few questions.

His answer is as follows- "The chassis is based from the 86 ATC and the weight depends on the version of the chassis. The Drag-Lite chassis for dunning and drag racing will end up about 13lbs lighter then stock with the MX version being about 6 lbs lighter then stock . I cant give a date as of yet when they will be available to buy because it all depends on how the testing goes. I'm building 3 test chassis so we will see how it goes. I wont stop until i have the chassis fitting and working like i want it to. - Dave

I'm freakin stoked about this and can't wait until he's ready to put them into production!! I will have one as soon as they are ready!

So Will this hold up for a 200 pound guy trail riding and private land riding this frame with inverts?

I would go with the MX version, If your at Glamis jumping dune to dune, jumping the gaps or jumping the canal, I would want the heavier frame.

I saw it asked but not answered about room for a 450 motor in it? By the pics I'm guessing no, but that would be awesome.

I asked the same ? I also sent him an email and didn't reply. I guess they are still testing away.

Is this Dave Moore the one at www.davemooreracing.com? I need to talk to him about one of these. Is there a better way to get ahold of him?

[250rRoostmaster]

I've sent him 2 emails over the past week about this with no reply. We have had a few email conversations about these frames though so I'm guessing he's just busy. He also has a phone number on his website.

He is still working on it. There are a few of us already on the unofficial waiting list (He wont take deposits and has said its done when its done on this first one) so just keep checking in on it is my suggestion
