Today I finished most of the throttle regulator except for the wire mount and some drilled holes for fitting the regulator to the air box, that will have to wait until I get the throttle grip I ordered a couple of days ago.
The holes for the fuel ports were drilled and threaded with R1/4" and the holes in the end were threaded to be blanked off.
With the holes blanked off and JIC 7/16" couplings fitted (same as AN4) the regulator looks like this. I will probably do something about the finish later when I know that it works like it should, until then it is a waste of time to do any polishing.
The next project for the evening was to continue building the air intake for the engine, I rolled an aluminum plate into the right shape and fixed it to the frame.
Then I split an aluminum tube to get a radius for the front wall of the air intake, this should make the ram air enter the air box a little bit better.
With those parts tacked together I could make a template of the side walls.
I only had enough aluminum for one side at home so I will have to go get the rest of my stash later.
This is what it will look like anyway, the engine looks smaller and smaller as the air intake grows but it is needed if the engine is to get particle free air. The Y2K bike at Bonneville hadn´t room for more than a crude screen and it hardly made it out of the pits despite its 400hp Allison 250 C18 engine.
One last thing I did before I called it a night was to sketch a bit more on the ram air intake on the fairing, I can sacrifice some intake area to get the looks right since the space between the fender and fairing lets lots of air through so the engine should get more than enough air anyway.
Cheers!
