runner airbox mods

The mount i made up for the kart airbox on the runner, i knew wasn’t a perfect engineering solution, it was only secured by two points, and both those points were aligned in the wrong plane (up and down). So, i welded up the cracks again and added a strap.

Worked well, very stiff, can put alot more weight on it

The extra bracing on the upper part is a bit redundant now.

Did i mention i brought it to a dyno, and it made 2bhp more over stock? doesn’t sound like a lot but it’s a round 8% moar power!

Just needs new tyres and to solid mount the engine, think i should get a 28mm carb and chuck the 24mm on the tuk tuk. Shopping!
