Not wanting to totally hijack Hoser's 3D printing discussion I thought I would start a new project thread about making a FL350 intake manifold. Disclaimers - This is my 1st FL350 and I have never worked on one before. I am not sure what is stock and what isn't. I am not a mechanic/fabricator/machinist nor do I have too much experience working with 2-stroke engines but I am crazy enough to do things like this.

When I finally got around to looking at my carb setup a bit more closely, I saw that I already have an aftermarket intake manifold like in Hoser's pic. Since my rubber adapter attaching the carb to the manifold is cracked, all I need to do is get a new adapter. I believe I have a Mikuni 38mm flatslide carb as its made by Mikuni, has a flatslide butterfly, and the carb outlet ID is 38mm. I am going to get an adapter so I can get the thing back together. But I still want to try and make my own intake just to say I did it (I am still fascinated at making useful parts on a CNC mill) but also to see if I can get a better match between parts along the intake path.

So I ordered an Oddatv intake as soon as I got my oddy without knowing/looking at the intake setup. So I now have what I am assuming is a stock intake manifold setup. This has the carb offset to one side of the intake. I also have my current intake manifold where the carb is centered. There is a huge difference between the 2 manifolds in the shape of the backside where they mate to the reed cage. I am going to try and copy my current straight/centered intake. My retired machinist buddy has a foundry he uses in Stockton (about an hour away) to cast aluminum parts. I will probably just hack the manifold out of a block of aluminum and may also explore making a mold/pattern and having it cast (like mine is). I will try to maintain dimensions and angles that my intake has.
Here are my questions so far:
1. Is my reed cage intake shape stock?
2. Is the offset only needed in a stock setup?
3. Where is a good place to get the rubber carb adapter?

the stock ones were offset to the side

Not to bash Odd, but that rubber is ugly! For the $ price, I'd expect a piece of artwork. Then again, I have been known to be a needy / picky customer. ;)

Careful when trying to match up the outlet side of the 'centered' intake with your reed cage / stuffer. Going from a circle to rectangle...you can run into some wall thickness problems really fast.

Pyrodude,

Just curious as to what has been done to make the carb clear the left side Engine to transmission mount.

Also what has been done to connect to the air box.

Thanks, Rand

By the way...you can get the rubber carb flanges at Parts Unlimited, Denis Kirk http://denniskirk.com, MfgSupply, Amazon, and evilBay. Look for "Mikuni carb flange" or look at the chart (below) and then search the net with the part no. for the best deal.

IMO, the Kimpex ones and whatever PU carries look cheap, and nowhere are their dimensions listed. I like the Minuki-branded ones a lot better and generally only run like $5-$6 more.

If you're not running a Mikuni carb (i.e. keihin), just check the Mikuni flange size chart and then a site like sudco.com for the Keihin carb dimensions.

Where u located out of ?

Buy only the he Minuki-branded manifolds the rubber is so much better and last longer.
