Hey all,
New guy from New Mexico here. Awesome site! I've read a lot of posts and gotten some great info, but needing more A.S. carb info Please!!
I have 2 1985 fl-350 odys, a racer I got in El Paso, and a all stock one I bought in Illinois on CL and had it shipped to NM.
The racer has carb issues. It came to me with a gravity feed dirtbike tank ratchet strapped to the back. I replaced it with a stock tank & mikuni fuel pump & it hasn't run for more than 5 min. since. I want to replace the carb with a 35 to 39 mm Air Striker but need some expertise. The machine has a liquid cooled head, Powerblock IBC Clutch(comet?), a DG pipe, a FMF turbine core 2 silencer, V Force 3 reeds, & a Mikuni TM-34 flat slide carb on stock intake with a UNI foam filter & no box.
Rather than screw with the old mik I would like to switch up to the PWK Airstriker I've read about. I like to haul ass in the racer so I thought to build it for speed & leave the stock 1 stock. I'm cheep so I thought a 35 might fit the orig. intake, but may need to get a new intake as well. I'm thinking a 250 elsenore or ATC straight intake or the cool 1 speed manufactures. If so do I want the PWK 35 AS or larger????? maybe the class it was in required a smaller carb? I run in deep river sand and dirt trails. do I need to stay small for the torque, I don't run WOT (Wide Open Throttle) in the Rio Grande too bumpy, kinda boggs a bit a low speeds.
So what would you advise for carb & intake?? Also should I purchase belt guards for safety - racer has none. Thank You for the HELP!!

I am running an Air Striker on a setup similar to yours and love it. IMO it is the perfect carb for a mildly modified Ody. I would go with the Air Striker 35mm. The larger carbs are more for running full throttle such as fire roads and dune running.

As far as manifolds go, the 35mm will fit into the stock manifold but it requires a little bit of stretching. If you are running a stock manifold then more that likely it is a bit on the crispy side which makes them prone to tearing where the boot starts to flare out. Unless yours is still good and pliable, you may need to purchase a new manifold. The straight Elsinore 250 manifold won't bolt straight up because it interferes with the left side transmission mount.

This is spot on. I just did the PWK A/S 35 the other day and I noticed the stress cracks in the area he just mentioned. I'm now looking for a new intake manifold because of it.

Thanks for the speedy reply!!
Do you happen to know which model I should order in light of the stock tank & pump? I caused the problem with the change to stock tank from gravity. I LIVE @ 4000'. I found a PWK 35 AS/S65 016.160 on amazon $179. free ship. I know I need xtra jets but I'd like to start as close as poss.

Is modding the trans mount a big deal? $45. & improved flow makes the straight manifold very attractive to me!

Which model.....I am running the Keihin PWK 35mm Air Striker quad vent carb. If memory serves me right, its the factory carb for a 2005 YZ250.

As far as the fuel delivery system goes, the use of the PWK Air Striker carb allows the removal of the "T" bypass valve and return line back to the fuel tank. All that is required is the delivery straight line to the carb directly from the fuel pump. Of course you will have to plug the fuel return line in the top of the factory Ody tank if thas what tank you decide to use.

Is modifying the trans mount a big deal.....all I remember is the bowl of the carb hits the transmission mounting bracket. I didn't want to make any modifications to the bracket so I went with an FL350 reproduction sold by Oddatv.

I would be more than happy to sell you the brand new Elsinore straight shot manifold which I will never use.

I don't know what kind of welding skills or fabrication skills you have but this is what I did to replace my torn intake manifold.

I can have another run of Dan-i-Folds made, but minimum order is 10.

What part of NM are you from? There are a couple of us in the ABQ area that get together & ride from time to time, & the more the merrier.

Count me in for 1.

I have a WTB for one of these that I just posted.....

Hey Guys,
sorry for the slow reply, been busy. Rand, don't know any more than what I listed. I was searching for a PWK 35 Air Striker & that's what came up-cheapest on Amazon. Do you think 160 is a good starter main jet? I would like to leave stock fuel system with bypass. Do I need a specific model for that? I think a Danifold may be in my future. I don't think I want to modify my trans brace.

Can Ody, Nice work, never welded alum. before, think I better buy 1. The Danifold is my1st choice, but is there a cheaper way to go? I live outside Las Cruces

No you don't need anything specific, I just prefer the quad vent Air Striker. You can still use the bypass valve but with the Air Striker, you don't need to. In my opinion, the bypass is just one more thing to fail.

With the mods you have I would purchase a range of jets from 160 to 170. Start fat and work your way down.

If I remember right, I am running a 165 at 5000 feet with similar mods. Don't quote me on that, its been a while since I've opened the carb up.

My mods are:

Hillside Honda Billet Aluminum Head
Power Pros pipe
No air box with a tripple wrapped pod filter
Stock reeds
Advance timing key

I made my own as it was the cheapest way to go, but you should go for the Danifold if he starts making them again. DON'T BUY the unit from aftersucks motorsports. It is total crap. You will have to cut the trans brace for it to fit, also it is center mount not off set like the original, also the rubber flange leaked and it won't seal even with silicone because the base which the flange mounts on is to small. Do I need to go any further with this piece of crap ?? How do I know ?? My brother bought one.
It's Danifold or make your own. Amen.

Thanks for the good press! There's a reason I had them made -- everything else sucked! After$shock ones were not offset and were overpriced. The ones from OddATV1 on evilbay look like hell, too. And the colored "urethane" ones on evilBay...look too flimsy. Plus people were trying to get a fortune for their petrified stock intakes.




Did not know this. Awesome!
