Case Reed 125 Hodaka Project

This has gotten a bit out of control. Stiffening up the swingarm is complete. Front section boxed in and arm rails added. It weighs 700g more than a stock wombat arm but the frame will break before the swingarm will. Paint to come.

Uh yeah, about frame breaking. Here is another good place to gusset.

Nice , I’ll have a look at this area

Part of the case Reed installation required removing some engine mount bracing to allow the carby to fit. It’s actually more like a road toad set up. I reinforced the rear engine mount with a doubler with 2 mm sheet metal to make up for it.

Some nasty porosity in the factory welds in that area on my frame

[thirdstone]

Ok I’ve done a bit of bracing in the frame area

Not pretty but functional. It’s a bit restricted in what can be done due to the seat mounting lugs.

Also attached is a picture of a Road Tiad frame. I can see what looks like extra bracing from the factory. I which I had seen that earlier .

I had the opportunity to make a adjustable pedal height for the brake pedal.
I think it’s worked well. Plenty of strength still on the footpegs mount as it’s solid not tube.

After a day of fabrication I have the silencer sorted out. It’s a DEP KTM125SX from 2002.I had to completely disassemble it , shorten 1 inch and put back together. You would think an easy job as it’s “ re- packable however DEP had bonded it so no amount to persuasion worked except the hacksaw.
I have fired up the bike , incredible throttle response if I say so myself. I haven’t ridden it yet because I live deep in a city.

Looking forward to hearing this beast run! Nice work.

No debate...you're correct!

[thirdstone]

Ok guys this is the best I can do for now.

Sorry , Try now its public

Sounds purty good!

Ok I think I’m done now, at least until I find a money tree. I’d really like to make a Chrome Molly frame and have some modern wheels but that’s a pipe dream . I’m really looking forward to riding it in a couple of weeks time . It’s been extremely fun to do even if I admit to more than usual swearing on some days .
Thanks for your interest in the project , it’s always nice to hear the point of view of others and of course the encouragement that came my way. You can’t do this in a vacuum.

Wow! What a great bike. I can't wait to see it in actions. You're quite a builder! Thank you for sharing the process.

[givergas]

i just rub my eyes in amazement when i see builds like that, very inspirational

[Dale]

Dang!!!

[Bullfrog]

Um . . . what Dale said!

Well after some constructive criticisms sticking in my head I dumped the airbox and made up a new design. This one allows a larger filter and reduces weight . I made a version with an aluminium mikuni “trumpet mouth “ and then a short while after I came across a 35deg reducing rubber elbow that allows a smooth taper from the filter to the carby inlet. I went with that one . Not sure if the two would be different to be honest.

[thirdstone]

I also fabricated an alloy chain guide . I’m hoping this will allow me to remove the chain tensioner.

Also on the go is a rebuild of the engine cases from V 1 of the case Reed design. I ran these cases for a year before I went to V2 that has the Reed block welded on to each half , it also allowed a larger Reed block. With the V1 redesign I’m making the Reed block from a KX85/100 fit so it’s slightly wider than a stock 97 Reed block . With a bit of filing I can get the Kawi block into the 97 Reed manifold but I might use the bill it block , not sure yet.
I’m making good use of COVID lockdown time.
