This is my first design of my Gen3 Aluminium Headstay, It took me all day cause I have never used an CAD drawing program. I think i did alright. All the plates will be waterjet cut out.
What are your throughts of it?

I am still designing the CDI and Coil mounts which will sit in the middle of the box section.

look around, make the thing brace to the shock tower area of the frame. 1/3 the weight/material and results in the same hold as every other honda two stroke. its simple and it works. Likely even use the side arms from the 4 stroke motor mounts if you wanted.

thats the only way to do it the cross brace style is junk you will never stop it vibrating and never keep your engine mounts tight
only posties ride 4 stroke hondas

I like your coolant manifold did you make it and are you using a 250 or 125 radiator?

Your coil mount is slick. Gonna try and use that idea on my '04.

Thanks Paul, i have something similar, I mounted the coil bolts 90* to the ones pictured so that the mount can be flipped over and its 5mm offset can hide the coil up higher if required. I've done them for cr5 and cr25 coils

How do you push the decomp? Burn you hand on the muffler? I know....you have gloves. Maybe it is easier than it looks. Can you hit it when you grab the kick start head?
