Honda leave gussets not welded like that, otherwise they crack as the loads flex the structure. The idea is to have welds in bending, so they weld along the 'neutral axis' of a joint (the bit that doesn't get longer or shorter as it bends i.e. avoid welding where the joint is in alternating tension & compression. It looks bad but the frame resists cracking much better than if it was fully welded. Fillet grinding and blending the welds so there is no abrupt change in section is a way to stop this cracking, but Honda definitely don't want to do that as it's too time-consuming (as you found out). Still I'd keep an eye out for cracks starting at those welds when you do routine maintenance - jv

@johnvreede832 That is awesome info, thanks for that. I will most definitely keep an eye on that area for cracks forming now.

@@spkslab ..especially since the metal stamped parts that make the frame rails are relatively thin whilst being a cheaper alloy of steel, some of the gaps in welding was to allow some flex in some directions only, allowing stiffeness in another axis of directional/dynamic forces. If the frame was all of the same alloy material for or a full on WSB/BSB/ASB/MotoGP, or/& tubular, then yes, all joint areas would be fully welded/brazed and with specifically cast/blended webs. Plus many small capacity Japanses (& Triumph) bikes, have many of the of parts (sub) assemblies made in other countries than only in Japan, such as Brazil, Thailand, Spain, where local region supplies can contribute into the production, so some of those same lesser than racing needed strength/quality looking methods of frame design & production, suit a wider mix of nations abilities without comprimsing the overall end result, as variance mitigation is already factored into the design. Sorry for the long paragpaph of text, I don't try to appear an a**hole, butt I feel sometimes..... ;¬)

Without a doubt today was awesome due to the video drop. Love how you explain everything. I cannot wait for your next video. Great job bud.

Thanks mate. I got the idea after doing a similar thing on a car chassis where I needed to pass the exhaust through a crossmember.

Thanks mate! I've got some ideas for paint in mind that I haven't seen on a bike like this before.

I believe the open joints -under- _behind_ the steering stop are weep holes.

@spkslab 3 ай бұрын

Ah ok, I did think after I filmed this that maybe they were meant to be there. Do you think I should drill some new ones into it?

@scottcates 3 ай бұрын

@@spkslab A couple 1/8" holes on the lowest point. Even an air gap helps water condensation off gas back into the air, I believe. I mean, if it's permanently airtight, then there wouldn't be a concern but it's probably a best practice to keep the bottom ends open for drainage.

Just a suggestion about metal types. I don't know if the original frame material is Chrome Moly but my 250 R ATV was and when I added mild steel gussets I ran into a cracking problem and had to replace them with Chrome Moly flat stock. I don't know if you will have the same point loading issues I did but just something to bounce off you.

@razor1uk610 3 ай бұрын

That is definately good and worthy to point out !!

@spkslab 3 ай бұрын

@matthewmoilanen787 To be honest I didn't think of that at all. I just assumed that this frame was mild steel as it was originally from a cheap commuter bike. I will do some research now to make sure it is actually mild steel. Thanks for the tip 👍

Ya can get some really cool scale fireblade race fairings for cbr125’ a from the Freetech lads in the UK

@spkslab 3 ай бұрын

Yeah I have been looking at those, and they are an option I am considering along with NSF250 fairings. I am going to try designing and making my own fairings first but if it doesn’t work out I’ll consider the Freetech fairings.

Hey, I'm absolutely loving the work you put on this frame. Roughly, at finished work, how many hours did you put in it? If you'd be willing to do the same work for somebody else, how much would you charge for the whole work? Hypothetically speaking. I would like to have something like that for a project of mine, but with a 200cc V2 two stroke engine.

@spkslab 3 ай бұрын

Thank you. I would guess there is around 50-60hrs (possibly more) in the frame so far, including the shock mounts I did in a previous episode. I have been designing and fabricating as I go with no plan to follow just enjoying the process and not worrying about time. If I was to complete something like this for someone else I would spend more time designing and planning before beginning work to reduce the hours involved in the fabrication process. I don’t generally take on commissioned jobs, however a 200cc V2 two stroke build sounds like an awesome project and is definitely something I would be interested in helping out with. If you want to contact me by email cheynespeak@gmail.com or instagram dm @spkslab we could discuss it further to see if we could work something out.
