That's a freaking piece of art work. After reading that link and looking at those builds I'm in awe. I'm even more excited to see how this turns out, sounds like the bike will handle even better once it's finished.
Started Fabricating the new inlet duct which should be way better in terms of flow and pressure recovery into the airbox.....
The stock arrangement is a bit of a compromise.....one thing I have noticed is the 2016 frame inlet duct has a couple of holes either side of the cast duct just before it enters the airbox...these according to Kawasaki are for noise attenuation for induction roar...these holes vent into the interior of the cast frame....the thing is the frame has a number of holes cast into it which are sealed with adhesive backed rubber patches.....these patches upon removing the frame from the motor were no longer sealing so probably would effect the inlet ducts ability to build and hold pressure into the airbox......I would suggest a fix would be to seal these holes in the inlet duct from the inside of the duct ...and so probably allowing a better ram air effect into the airbox.....
This shows Kawasakis use of the frames internal volume as a resonator to reduce intake noise.....I am very very doubtful of this....its probably just a good source of leakage of the inlets Ramair system....
Very bad idea. Funnel shaped intakes cause turbulence into the airbox. It messes up resonance, flow, atomization etc all of which lead to consistency issues with the fueling.
LDH,
meant not funnel type, my english is very limited in this regard.
I meant that the entrance, does not have those sharp lips, and could be more like a open mouth....
and that the overall volume could be bigger since it has space for it.
Just completed the first stage of the build with zero issues or problems......the modified gen 4 frame fits nicely with the Gen 5 motor swingarm and linkages.....the swingarm pivot position in the Gen 4 frame in its present orientation looks to be a very close match with the previous position in the Gen 5 adjustable pivot with the +2mm Kit spacers installed....as I hoped it would.
So now to make a mount for the dash...tidy up the electrics ....measure up a new radiator and find a spot for the ignition key barrel......amongst a host of other fiddly bits and pieces......
This conversion is looking to be the same weight as the original fork setup......I had not paid any attention to light weight tho so quite happy with that....
